Real Time Collaborative Whiteboard

This experiment developed a whiteboard web application that will be versatile, hence usable both as a tool in teaching and one in entertainment. There is a pencil of all sizes and colors allows people highly to customize the drawing capability. It has several shapes-circles, rectangles, lines-for structured illustrative works. The platform can also be allowed for free-hand drawing and sketching for artistic expression or note-taking. An important feature of the application is the non-stuttering user interface during transit from one tool to another. Hence, it is perfect for live lesson educators or busy people working on creative tasks. A desirable feature of the application is that it has a "Save as Photo" function where the work can be captured in the image format and shared with colleagues or preserved for eventual review. This connects the user from the old means of whiteboards to the new avenues of digital interfaces, thereby enriching interaction in learning environments online and serving as a fun way of creativity and entertainment. The user base of the whiteboard application is encompassed by students and teachers, hobbyists, and artists, due to its wide-ranging intuitive control, size and color customization, and shape-drawing tools. This makes it a widely-used, enabling tool for digital content creation and collaborative work.

No One Right Approach; A Review of 21st Century Skills Pedagogy in Eswatini Curriculum

Purpose: The 21st century skills curriculum is adjusted in different ways to meet each country’s education needs. This study is a review of how the 21st century skills curriculum is adapted in the Eswatini General Certificate of Secondary Education (EGCSE) curriculum. Its objectives were; to ascertain the vision of the 21st century skills curriculum as embraced by the EGCSE curriculum; to explore the interpretation of the 21st century skills pedagogy in the EGCSE curriculum and to examine other legal documents that embrace the notion of 21st century skills in Eswatini. Methodology: It adopted the systematic literature review methodology. Four (N=4) documents were analysed to determine 21st century skills. These are the P21 Framework, the IGCSE Consultative Document for 2005, the National Curriculum Framework for General Education and the Eswatini Education and Training Sector Policies (EETSP) for 2011 and 2018. Findings: The findings revealed that the 21st century curriculum philosophy is captured in the P21 framework and EGCSE curriculum in similar ways, as learner-centred and constructivist in design. The P21 Framework interprets the 21st century skills as; learning and innovation, information, media and technology skills and career skills. Contrary, EGCSE pool them together as; communication and language, numeracy, problem solving, technological awareness and applications, critical thinking, work and study, independent learning and working with others. Other legal documents that embraced the notion of 21st century skills were the Competency-based Curriculum Framework, the National Curriculum Framework for General Education and the Eswatini Education and Training Sector Policy for 2011 and 2018 within which there are two (2) sub-policies; Inclusive education, Education for All. Unique Contribution to Theory, Policy and Practice: Though put differently, the 21st century skills in both frameworks are similar; they empower learners with ways of thinking and working, tools for working and living in the world. Also, only summative assessment is captured, a few is said on formative. It is recommended that both frameworks be revised for more speculations on formative assessment strategies. For teachers to understand the EGCSE curriculum, they need to refer to the other documents or policies.

Investigation of the Effect of Al2O3 Nanoparticle-Added MQL Lubricant on Sustainable and Clean Manufacturing

In this study, in order to improve the characteristics of the vegetable-based cutting fluids used in the MQL technique and increase the machining performance of MQL and its positive effects on sustainable manufacturing, the effects of the MQL method with nano-Al2O3 additives on surface roughness (Ra) and cutting temperature (Ctt) were examined through turning experiments carried out by adding nano-Al2O3 to the vegetable-based cutting fluid. For this purpose, machining tests were carried out on hot work tool steel alloyed with Cr-Ni-Mo that has a delivery hardness of 45 HRC. In hard machining experiments, three techniques for cooling and lubricating (dry cutting, MQL, and nano-MQL), three cutting speeds (V) (100, 130, 160 m/min), three feed rates (f) (0.10, 0.125, and 0.15 mm/rev), and two different ceramic cutting tools (uncoated and TiN-coated with PVD methods) were used as control factors. For Ra, the nano-MQL method provided an average of 21.49% improvement compared to other cooling methods. For Ctt, this rate increased to 26.7%. In crater wear areas, the nano-MQL method again exhibited the lowest wear values, decreasing performance by approximately 50%. The results of this research showed that the tests conducted using the cooling of nano-MQL approach produced the best results for all output metrics (Ra, Ctt, and crater wear).

Governance of healthcare quality: exploring the relationships between hospital board performance and healthcare quality outcomes

PurposeThis paper aims to contribute to the existing literature in the field of hospital governance by exploring the relationship between the attributes and performance of hospital boards and hospital performance in terms of quality of healthcare.Design/methodology/approachA survey of board performance in public hospitals in Morocco was carried out, in which we surveyed all board members of the 13 hospitals in the Casablanca-Settat region. A total of 82 members responded (82% response rate) to the previously adapted and validated self-evaluation questionnaire on board self-assessment questionnaire (BSAQ) board member performance.FindingsOn average, the hospital boards studied had eight members. In terms of clinical expertise, half the members were physicians and 17% were nurses. In addition, positive correlations were found between certain board characteristics, notably age, seniority, members' perceptions of their impact on the quality of healthcare and several dimensions of board performance. In parallel, the results showed strong and significant associations between turnover rate and BSAQ score. Negative correlations were also found between average length of stay and BSAQ score. With regard to mortality parameters, it should be noted that we were unable to establish a strong empirical correlation between hospital boards' self-assessed performance and other hospital mortality indicators.Research limitations/implicationsThe present study offers a rigorous rationale for the use of the French-translated BSAQ in the hospital context, and we hope that others will use this tool in future work within the framework of evidence-based research. In addition, the BSAQ tool’s focus on board competencies (and not just structure, composition or processes) provides valuable insights into what boards need to learn in order to function effectively. However, despite the insistence of the authors of this study on the need for a comprehensive census of public hospital board members in the region, several obstacles were encountered. Firstly, there were difficulties related to vacancies within the hospitals, which had the effect of restricting the representativeness of the sample. Secondly, access to hospital board members proved complex due to their busy schedules and the confidential nature of their meetings. Finally, it is important to note that national performance indicators in Morocco may not be as reliable as in other countries, which could complicate the identification of high-performing hospital systems and, consequently, make inference difficult.Originality/valueThis study provides large-scale empirical evidence of processes related to the governance of quality of healthcare and elucidates the existence of an association between hospital board performance and clinical performance. The use of validated tools such as the BSAQ should therefore help improve the performance of boards and governance in public hospitals.

Redesign of stroller work tools at PT. Ika Bina Agro Wisesa

PT. Ika Bina Agro Wisesa (PT. IBAS) is one of the agro-industries that manages or produces palm oil with a production capacity of 30 tons / hour and a total of 420 tons / day. The raw material of Fresh Fruit Bunches (FFB) of this factory comes from the plantation land of the community around the factory. The activity of harvesting FFB in this oil palm plantation has many manual material handling activities, especially for workers who lift and push wheelbarrows (angkong). The angkong work tool used is relatively old and looks unergonomic which can be seen when pushing the angkong in a very bent position so it is assumed that there is a large amount of force expended by workers. This research begins with a survey of the company and the field, then distributing Nordic Body Map (NBM) questionnaires to workers, using the Rapid Entire Body Assessment (REBA) method used to determine the level of risk of work posture in workers before and after the design of the tool, for the redesign of the stroller, anthropometric measurements are taken then using the Biomechanics method to determine the amount of force generated when pushing. This stroller redesign was carried out using operator anthropometry with the 95th percentile. After using the proposed tool, the work posture assessment is categorized as moderate which means that action is needed. The final results of the redesign are the length of the cart 90 cm, the width of the cart 66 cm, the diameter of the tire 32 cm, the height of the cart from the ground 125 cm, the height of the handle 96 cm, the width of the handle 40 cm, and the diameter of the handle 3 cm and the final results of the biomechanical assessment after the design concluded that the operator was no longer dangerous when pushing.

The Introduction of Automation in Control of Virtualized Laboratory Complex Components at Higher Educational Institution

The intensity of the use of remote work and learning tools has increased significantly during the pandemic and has led to the emergence of new tools and a significant increase in the capabilities of previously developed technology platforms. The introduc­tion of modern technologies based on software control and complex visualization for the creation of virtual laboratory complexes in educational institutions provides virtually unlimited opportunities for organizing individual and distance forms of practical classes. Modern learning management platforms that able to integrate with the database of university students makes it possible to evaluate the quality of students' work with various types of course learning materials in real time. The article shows that the use of virtual communication infrastructures in connection to the Moodle learning management platform will provide end-to-end control of the theoretical and practical components of the educational process and will automate the processes of preparing and conducting practical classes, which will improve the quality of the educational process and the teacher efficiency.

Validity of the Oral Hygiene Ability Instrument (OHAI).

To evaluate the validity of the newly developed Oral Hygiene Ability Instrument (OHAI), created to assess the cause of any inability of older adults to perform oral hygiene, and to revise the instrument based on the results. Good oral hygiene is among the most important prophylactic measures for oral health. This applies especially to older adults, among whom risk factors and physical and cognitive barriers are more common and can hamper oral hygiene. The OHAI contains (I) an interview, (II) clinical examination, (III) observation of oral hygiene activities and a summarising part. In the study, 149 older adults in three groups participated: stroke, cognitive disorder and general dental patients. Inclusion criteria were to be ≥65 years old, have at least one tooth and to manage oral hygiene without assistance. For criterion validity, sensitivity and specificity were calculated using eight reference instruments. To determine construct validity, we used known group validity, factor analysis and Rasch analysis. The criterion and construct validity of the OHAI were found to be acceptable to good. In the stroke group, balance and fine motor skills were assessed to affect oral hygiene most; in the cognitive disorder group, it was balance, coordination, spatial ability and cognitive functions. Analyses revealed that one item had no added value and that some response options were not optimal. The OHAI proved to be valid for the group it is intended for, with only minor revisions needed, resulting in a 32-item instrument. The OHAI could be a valuable person-centred tool in prophylactic work with older adults with failing oral hygiene.

Durability of Forging Tools Used in the Hot Closed Die Forging Process-A Review.

The article presents the classification of the wear mechanisms of forging tools. The durability of dies can be enhanced through a variety of methods, including the selection of appropriate hot working tool steel, the application of effective heat treatment, the utilization of advanced surface engineering techniques, and the incorporation of lubricating and cooling agents. Two popular methods of tool regeneration, such as re-profiling and laser regeneration, are presented. The issue of numerical wear prediction based on the Archard model, the correlation of this model with experimental results, low-cycle fatigue (HTLCF), and an alternative method based on artificial neural networks are discussed. The paper aims to present currently known wear mechanisms and the methods of increasing and predicting tool durability.

Improved tools for estimation of ammonia emission from field-applied animal slurry: Refinement of the ALFAM2 model and database

Ammonia volatilization from animal slurry applied to agricultural fields reduces nitrogen use efficiency in agriculture and pollutes the environment. This work presents new versions of a model and database focused on this route of N loss. The public ALFAM2 database (https://github.com/AU-BCE-EE/ALFAM2-data) was expanded with ammonia emission and ancillary measurements for >700 additional field plots. The ALFAM2 model (https://github.com/AU-BCE-EE/ALFAM2, https://zenodo.org/records/13312251) was extended with the addition of an ammonia sink for more plausible predictions over extended durations and to better reflect the expected reduction in emission rate several days after slurry application. A new parameter set was developed for the model taking into account the newly available measurement data. Model efficiency improved to 0.67 for the parameter estimation subset (0.52 for cross-validation) and mean absolute error was around 10% of applied total ammoniacal nitrogen. As in earlier versions, predicted emission is sensitive to application method, slurry dry matter and pH, air temperature, and wind speed. A collection of parameter sets for estimating uncertainty in average predictions was developed using a bootstrap approach. Predicted uncertainty is not trivial, and is high for some variable combinations, highlighting the challenge of making predictions based on available measurement data. Still, this work has resulted in more accurate, comprehensive, transparent, and flexible tools for emission inventory and related work on ammonia loss from field-applied slurry.

Tool life improvement for stamping dies in the coining process

ABSTRACT High temperature and high-speed pressing in minting operations lead to the failure of coin-stamping dies. As a result, new coining tools were required more frequently leading to lower operational productivity and higher production costs. This research has examined the effects of materials and surface coating selections on the tool life of the stamping dies in the coining process. The aim of this research was to explore the possibility of extending the tool life of stamping dies. The three kinds of materials under study were alloy tool steel, cold working tool steel, and hot working tool steel. Additionally, Titanium Nitride (TiN) and Chromium Nitride (CrN) surface coating materials using the Physical Vapour Deposition (PVD) process were investigated. The experiment results revealed that the hot working steel yielded the highest tool life of up to 1,300,000 coins, followed by cold working steel at 900,000 coins, and alloy tool steel at 600,000 coins. The CrN PVD coating provided up to more than 400,000 coins compared to TiN PVD coating on hot working tool steel.

The effect of cryogenic treatment on a high Co bearing DIN 1.2888 steel used as die in hot forging process

Abstract Hot work steels used as dies in metal forming processes must endure harsh conditions, typically achieved through a martensitic structure. However, retained austenite can persist after martensitic transformation, negatively impacting mechanical properties. Cryogenic treatment (CT) refines martensite, reduces retained austenite, and increases fine carbide density, thus enhancing performance. DIN 1.2888, a hot work tool steel with high cobalt content (~10%) and low carbon content (~0.2%), is less studied concerning the effects of CT. The objective of this study was to investigate how cryogenic treatment affects the mechanical and microstructural properties of DIN 1.2888 steel. Samples underwent conventional heat treatment (HT) and CT at -100, -140, and -180°C for 6 hours, followed by double tempering. Various analytical methods, including X-ray diffraction (XRD), scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS), and Vickers Microhardness tests, were used to examine the samples. Wear mechanisms were evaluated through pin-on-disc tests under different loads, and impact toughness was measured both at room temperature and the working temperature of dies (350°C). Results indicated that lowering the cryogenic treatment temperature resulted in a slight increase in hardness values from 507HV for the heat-treated sample to 529HV for the sample treated at -180°C. Additionally, the impact toughness improved significantly, with values rising from 12.35J for the heat-treated sample to 23.44J at 350°C for the cryogenically treated sample at -180°C. Wear rates also decreased by approximately 50%, particularly at higher cryogenic treatment temperatures. The improvement in wear resistance was attributed to finer carbide precipitation and a more homogeneous distribution of carbides. These findings suggest that deep cryogenic treatment has a positive effect on DIN 1.2888 steel by decreasing retained austenite and increasing fine carbide density, leading to enhanced mechanical properties and extending the lifespan of the steel in die applications.

Identifikasi Added and Non-Value Added activities Melalui Analisis Just In Time Pada Pekerjaan Pondasi Bore Pile

A construction project is a complex job because it involves various resources to achieve the targets of the project. Management of these resources must be carried out with the aim of achieving high productivity. The aim of this research is to determine activities that have added value (Value Added activity) and activities that do not have added value (non-Value Added activity) as well as to evaluate the productivity efficiency of machines and tools in Bore Pile foundation work. The author uses the Just In method Time to identify the effectiveness and efficiency of Bore Pile foundation work. Just In Time will focus on reducing waste so that it can increase productivity. The application of the Just In Time method is only used for resources, namely machines and tools needed for a job. This method will be assisted by the Manufacturing Cycle Effectiveness concept to measure the percentage of Value Added activities. The research results show that there are still several machines or heavy equipment with a percentage of non-Value Added activity that is greater than Value Added activity. This is caused by quite a lot of waiting time and Moving time, resulting in smaller Value Added activity.

The Relationship Between Knowledge And Attitudes Towards Ergonomic Behavior Of Employees At Upt Lik Magetan District

Ergonomic problems are related to the body's suitability to work tools when performing work tasks. Based on an initial study conducted by researchers on 10 employees at UPT LIK, Magetan Regency. There are 7 out of 10 workers who lack understanding about ergonomics such as how to lift weights, the maximum limit of the weight lifted, the use of Personal Protective Equipment (PPE), the effects of excessive weight lifting. Meanwhile, in the IKM section, understanding the principles of ergonomics is very important, because the work done by employees is closely related to ergonomics. The lack of awareness of workers in implementing ergonomic behavior is influenced by knowledge factors and work attitudes. Poor work knowledge and attitude are caused by the lack of ergonomics application by the industry to workers. In addition, workers also lack understanding of ergonomics in the work environment. This type of research is a quantitative research with cross sectional research. The population in this study is 230 respondents with a sample of 70 respondents in this study. The data of this study was obtained from the collection of questionnaire sheets and observation sheets. Data analysis using the Chi Square Test. The results of the bivariate test in this study showed that there was no relationship between the independent variable of knowledge and ergonomic behavior with p = 0.687 and there was a relationship between the independent variable of attitude and ergonomic behavior with p = 0.000 The conclusion in this study is that there is no significant relationship between knowledge and ergonomic behavior and there is a significant relationship between attitudes to ergonomic behavior. Keywords: Knowledge, Attitude, Ergonomic Behavior

Optimising acceptability using a user-centred design approach of a robotic software in Industry 4.0: A case study

While robotics and collaborative robotics are becoming increasingly commonplace in industry, operators do not always have full control over these tools. The aim of our robotics software is to give operators back the power to act. A user-centered design approach (UCD, ISO 9241-210, 2019), through four steps, has therefore been put in place within Industry 4.0. The first study aims to understand and specify the context of use through three objectives: to understand the organizational context in which the robotic software is to be designed and implemented, to characterize the end users via primary personas, and to take an interest in the operators' work in order to predict likely future situations and guide the development of the new work tool. The second study aims to specify user requirements using a card sort based on different criteria (ergonomic, UX). The third study presents the design solutions for version 2 of the robotics software. The fourth study evaluates and compares the practical acceptability (UX, usefulness, usability, mental load) and social acceptability (intent to use) of the first and second versions of the robotic software. Our results show, among other things, a significant improvement in acceptability for the second version of the software, suggesting greater acceptability of this technology thanks to the UCD approach.

The Impact of E-books on Thai EFL Undergraduates' Acquisition of Affixes and their Contentment with This Medium

The learning of affixes (prefixes and suffixes) by English as a Foreign Language (EFL) undergraduates is paramount since it enhances their vocabulary and helps them achieve fluency and proficiency in the English language. This paper aims to evaluate students’ command of affixes by using an electronic book (e-book) as a teaching method and examining students’ level of satisfaction regarding the learning of affixes through the e-book. The study employed a mixed-methods research design and included a sample of 50 first-year English for Communication students from Rajamangala University of Technology, Srivijaya. The research instruments used in this study included the pre-test, post-test, and an e-book satisfaction questionnaire, respectively. An interview was also used as a data-gathering tool in this research work. The findings indicated that the post-test results (26.40) yielded a superior outcome compared to the pre-test results (17.80). Furthermore, the e-book had an overall satisfaction rating of 4.57. In conclusion, the study found that students can significantly enhance their understanding of affixes, specifically prefixes and suffixes, by using unique e-books. For English teachers who encourage the use of e-books, the study's findings will have important implications since they will be able to use e-books for various uses in their respective classes when teaching EFL students.

Corrosion Resistance and Fracture Toughness of Cryogenic-Treated X153CrMoV12 Tool Steel

Abstract Cryogenic treatment can be employed as an additional heat treatment step for martensitic steels, particularly high-carbon and high-alloy tool steels, to improve their mechanical properties and wear resistance. This enhancement results from a transformation of retained austenite and precipitation of finely distributed secondary carbides. The present study examines the impact of a shallow cryogenic treatment, performed between the quenching and tempering processes, on the corrosion resistance and fracture toughness of cold work tool steel X153CrMoV12. The influence of the shallow cryogenic treatment was evaluated using potentiodynamic polarization test, salt spray tests and three-point bending tests in various hydrogen charging conditions. In addition, the microstructure and phase transformation of the tool steel were investigated using high-resolution scanning electron microscopy, X-ray diffraction and dilatometer tests. The results suggest that the shallow cryogenic treatment followed by a single tempering cycle can slightly enhance the corrosion resistance of the steel. More importantly, the shallow cryogenic treatment positively affects fracture toughness and reduces hydrogen susceptibility. It is discussed how these improvements in the properties of the X153CrMoV12 steel are linked to the microstructural changes induced by the shallow cryogenic treatment.

On the Origin of Enhanced Tempering Resistance of the Laser Additively Manufactured Hot Work Tool Steel in the As-Built Condition

Abstract In laser additive manufacturing (AM) of hot work tool steels, direct tempering (DT) of the tool from as-built (AB) condition without prior conventional austenitization and quenching results in enhanced tempering resistance. To date, intercellular retained austenite (RA) decomposition, leading to a shift in secondary hardening peak temperature, and finer martensite substructure are reported to be responsible for such a behavior. In this work, authors aimed at studying the strengthening contributions by performing isothermal tempering tests for long times (up to 40 hours) at elevated temperatures (up to 650 °C) on DT and quenched and tempered (QT) specimens. The thermal softening kinetics and the microstructural evolution were evaluated with the support of computational thermodynamics. The results suggest that the main contributor to enhanced temper resistance in DT condition is the larger fraction of thermally stable and extremely fine (~ 20 nm) secondary (tempering) V(C,N) compared with QT. This could be explained by the reduction of available V and C in austenitized and quenched martensite for a later secondary V(C,N) precipitation during tempering, because of equilibrium precipitation of relatively large (up to 500 nm) vanadium-rich carbonitrides during the austenitization process. A complementary effect of the substructure refinement (i.e., martensite block width) in rapidly solidified highly supersaturated martensite was also quantified in terms of Hall–Petch strengthening mechanism. The significant effect of secondary V(C,N) was successfully validated by assessing a laser AM processed vanadium-free hot work tool steel in QT and DT condition, where no significant differences in strength and temper resistance between the two conditions were evident.

FeSi-NiAl composite as a future tool material

Composite materials based on NiAl matrix and FeSi reinforcement are tested as potential tool materials in this work. The components (FeSi, NiAl) were prepared by mechanical alloying separately, blended and consolidated by spark plasma sintering method. The results showed that the composite blend can be successfully sintered at 1000 °C. Thermodynamic calculations were performed in SW Thermo-Calc, ver. 2019a for obtaining the phase diagrams of the studied systems. The composite has the hardness almost comparable with the heat-treated cold work tool steels. The hardness increases with the growing amount of silicide in the mixture. The same trend can be slightly visible also in wear resistance and the results nearly reach the performance of high-grade cold-work tool steels but having lower friction coefficient. The ultimate compressive strength reached values of 1830–2640 MPa, depending on chemical composition. The result indicate that these materials could reach the performance of the high grades of tool steel, but without the need for any heat treatment, which makes them to be a really promising eco-friendly alternative.

Evaluation of asbestos dispersion during laser ablation of rocks containing Naturally Occurring Asbestos (NOA)

Health risks are often overlooked when the short-term consequences are not immediately apparent. During restoration work, cleaning actions can generate particles that pose health risks to workers through inhalation. This is particularly true in the case of asbestos fibres that might be spread out from the laser cleaning of buildings or heritage artifacts made of stone, such as serpentinite and other ultramafic rocks, that have a high probability of containing asbestos (e.g., chrysotile, tremolite asbestos, actinolite asbestos). To show workers the importance of wearing proper protection to prevent health injuries, several serpentinite samples, ascertained to contain asbestos minerals by specific investigations, have been laser ablated using ad hoc modified equipment in order to collocate a HEPA filter prone to collect all dust emitted during ablation. The powder deposited on the surface of these filters after laser ablation was analyzed, by Powder X -ray Diffraction (PXRD), Transmission Electron Microscopy combined with Energy Dispersive Spectroscopy (TEM/EDS), micro-Raman spectroscopy (μ-Raman) and Fourier-transform infrared spectroscopy (FTIR/ATR). The results confirmed the presence of asbestos fibres during the laser ablation of rocks containing Naturally Occurring Asbestos (NOA), emphasizing the importance of wearing appropriate personal protective equipment (PPE) during these procedures. Noteworthy, approximately 33 % of the analyzed fibres met the WHO criteria in size for respirable fibres. Furthermore, through our experiments, we also demonstrated that using tools that integrate filters into working tools would definitively further decrease the risk of fibres inhalation to workers.

Drone System Remotely Controlled by Human Eyes: A Consideration of its Effectiveness When Remotely Controlling a Robot

In recent years, Japan has experienced numerous natural disasters, such as typhoons and earthquakes. Teleoperated ground robots (including construction equipment) are effective tools for restoration work at disaster sites and other locations that are dangerous and inaccessible to humans. Using visual information obtained from various viewpoints by a drone can allow for more effective remote control of a teleoperated ground robot, making it easier for the robot to perform a task. We previously proposed and developed a remote-controlled drone system using only human eyes. However, the effectiveness of using this drone system during the remote control of a robot has never been verified. In this paper, as the first step in verifying the effectiveness of the remote-controlled drone system using only the eyes when remote-controlling a robot, we consider its effectiveness in a simple task based on the task times, subjects’ eye fatigue, and subjective evaluations of subjects. First, the previously proposed drone system is briefly described. Next, we describe an experiment in which a drone was controlled by the eyes using the drone system while a robot was controlled by hand, and an experiment in which both the drone and robot were controlled by hand without using the drone system. Based on the experimental results, we evaluate the effectiveness of the remote-controlled drone system using only the eyes when remote-controlling a robot.
