UltraButton: A Minimalist Touchless Multimodal Haptic Button.

We present UltraButton a minimalist touchless button including haptic, audio and visual feedback costing only $200. While current mid-air haptic devices can be too bulky and expensive (around $2 k) to be integrated into simple mid-air interfaces such as point and select, we show how a clever arrangement of 83 ultrasound transducers and a new modulation algorithm can produce compelling mid-air haptic feedback and parametric audio at a minimal cost. To validate our prototype, we compared its haptic output to a commercially-available mid-air haptic device through force balance measurements and user perceived strength ratings and found no significant differences. With the addition of 20 RGB LEDs, a proximity sensor and other off-the-shelf electronics, we then propose a complete solution for a simple multimodal touchless button interface. We tested this interface in a second experiment that investigated user gestures and their dependence on system parameters such as the haptic and visual activation times and heights above the device. Finally, we discuss new interactions and applications scenarios for UltraButtons.

Design and Development of Smartphone Application Control

Smartphone Application Control is a project designed to block other phone applications that have excessive use by users. Excessive phone use is often experienced by children aged 7-18 years old. At the same time, many parents nowadays do not have time all day long to monitor and limit the use of their children’s phone due to work. The efforts of the mass media to advise on the use of phone do not give much positive impact on these children. Therefore, a robust alternative such as Smartphone Application Control is essential to curb these issues. To develop this application, a methodological approach has been used namely the Evolutionary Prototyping model. Android Studio version 3.6.2 is used to develop this application while SQLite Database acts as a database for storing all application usage statistics and Google-Cloud Firebase is used to store user-related information for user authentication purposes. To create an attractive user interface, Adobe Photoshop CS6 is used to design background and interface buttons. This app is able to track usage hours of other apps and block them if they exceed their daily usage limits. The time limit for such use can only be set by parents. Additionally, notification of excess usage will be sent to parents via email as a notification. A pop-up alert notification will be issued when user has reached his or her application limit. Smartphone Application Control is very important in helping user to control their phone usage behaviour.

PROTOTYPE SISTEM PENGENDALIAN PERANGKAT ELEKTRONIK BERBASIS IOT (INTERNET OF THINGS) MENGGUNAKAN VOICE CONTROL DAN BLYNK

With the IoT based prototype electronic device control system, users can control electronic devices at home. Commands can be done in two ways, namely using voice or voice control with the Google Assistant application and using the interface buttons on the Blynk application. The prototype system can control electronic devices on and off and can control fan speed. The main component uses NodeMCU as a microcontroller that is equipped with a WiFi module so that it can be connected to the WiFi network needed to be connected to the internet. This system works when the user gives voice commands to control electronic devices via Google Assistant or the user can also control electronic devices by pressing a button on the Blynk application. Based on the results of testing the success of controlling using the voice control system has an average success of 100%, and testing the success of controlling using the Blynk system has an average of 100%. While the measurement of delay when controlling using voice control, each command has an average delay of 15.8797 - 17.9731 milliseconds, and while for testing using the interface button on the Blynk application, each command has an average delay of 15.8926-17. 5463 milliseconds.

Interactive Content Using Newtro With A Focus On Hand Interface

With recent advancements in technology, there has been a tendency to increase the amount of interactive content, e.g., technology combined with cultural content. Based on this, interactive content has been created based on ‘Newtro.’ In view of the physical interactions between users and content, interactive content with an interface for connecting users and content was set as the object of this study. To apply the physical interaction (considered the most important aspect of the content), ‘a button interface’ requiring a relatively greater force was used. When the user pressed the button, the video was played on a projector. The physical interactions between users and content were discussed, and an interface for connecting users and contents to thereby apply physical interactions to content was studied. A questionnaire survey was conducted, targeting users who experienced the content, and research results were derived. Therefore, this study is meaningful in that it addresses the physical interactions between users and content and examines the correlation between the physical interface and interaction. Although using a button interface was helpful for the physical interaction, a relatively simple technique was used; this could reduce user interest in the content. Therefore, research on interactivity and interfaces that can promote more active communication between content and users is required.

Development and construction of a didactic module of electrical circuits for remote experimentation through a web application and IoT resources

This article presents the development and construction of a didactic kit of practical experiences of electrical circuits, remotely controllable through the internet, from low cost resources and devices, and easy to implement. Developed with open source technologies, the practice module was built from a Raspberry Pi, and subdivided into four parts: a web application (developed in Html, Css, Javascript, PHP and MySQL) and a local application coded in Python and runs on the Raspberry; two electronic boards, one for controlling the resistors of a circuit and the other as a variable power supply for the circuit; a cabinet designed and built in MDF to accommodate all the physical components of the equipment; and a mixed electrical circuit for experiments, consisting of 9 resistors, 10 voltmeters and 3 ammeters. To access remotely, a Login system was built, generating greater security and a button interface that, when triggered, make requests to a server, recording the status of the button pressed in an SQL Database (Structured Query Language). Tests were carried out to check the integrity of the hardware and software devices of the didactic kit, considering that they did not present any flaws, allowing the equipment to be installed in a physics laboratory, connected to the internet and made available intermittently for use by high school students.

Prototype development of tethered underwater robot for underwater vessel anchor release

<p>Tethered underwater robot (TUR) for underwater vessel anchor release is presented. In off-shore oil and gas enviromnment, there has been series of reported cases on stuck vessel anchors after mooring operations and divers are sent to release these anchors for the vessels to be in motion. The use of divers to perform such function is very risky because of human limitation and some divers have been reported dead on the process due to high pressure underwater or being attacked by underwater wide animals. This has caused very serious panic to the vessel owners and hence, this work is aimed to develop TUR that would be used by the vessel operators instead of divers to release the stuck anchor without loss. The underwater robot system comprises of three basic sections namely graphical user control interface (GUCI) that would be installed in the operator’s laptop, the WiFi LAN router for network connection, and TUR system hardware and software. Each of these sections was strictly designed. Various high-level programming languages were employed to design the GUCI and code the interface buttons, robot controller program codes etc. The implementation carried out and the prototype system tested in the University of Port Harcourt’s swimming pool of 6m depth for validation. The robot performed extremely good in swimming and release of constructed anchor underwater.</p>

Evaluation of different interface designs for human-machine interaction in vehicles

In this paper we report on a user study in which we compared three different interaction designs in an in-vehicle infotainment system. Touchpad, free-hand and ordinary button interface designs were compared for usability, user experience and how they affect driving safety in different driving conditions. The study was performed in a high-fidelity driving simulator. Thirty participants were divided into two groups, one with less demanding and one with more demanding driving conditions, with the purpose of evaluating the interaction designs also in different driving environments. Each participant completed a set of tasks on each interface design and evaluated it with the User Experience Questionnaire. The conclusion from this study is that using a buttons-based input design on the steering wheel is the most efficient type of interaction compared to touchpad and free-hand input designs. On the other hand, we found that although newer input designs could be very attractive, their implementation into the vehicles infotainment system should be done wisely and carefully.

Performance Evaluation of a Foot Interface to Operate a Robot Arm

Robotic minimally invasive interventions typically require using more than two instruments. We thus developed a foot pedal interface which allows the user to control a robotic arm (simultaneously to working with the hands) with four degrees of freedom in continuous directions and speeds. This paper evaluates and compares the performances of ten naive operators in using this new pedal interface and a traditional button interface in completing tasks. These tasks are geometrically complex path-following tasks similar to those in laparoscopic training, and the traditional button interface allows axis-by-axis control with constant speeds. Precision, time, and smoothness of the subjects' control movements for these tasks are analysed. The results demonstrate that the pedal interface can be used to control a robot for complex motion tasks. The subjects kept the average error rate at a low level of around 2.6% with both interfaces, but the pedal interface resulted in about 30% faster operation speed and 60% smoother movement, which indicates improved efficiency and user experience as compared with the button interface. The results of a questionnaire show that the operators found that controlling the robot with the pedal interface was more intuitive, comfortable, and less tiring than using the button interface.

Expert Surgeons Can Smoothly Control Robotic Tools With a Discrete Control Interface

Objective assessment of surgical skill is gaining traction in a number of specialty fields. In robot-assisted surgery in particular, the availability of data from the operating console and patient-side robot offers the potential to derive objective metrics of performance based on tool movement kinematics. While these techniques are becoming established in the laparoscopic domain, current assessment techniques for robotic endovascular surgery are based primarily on observation, checklists, and grading scales. This work presents an objective and quantitative means of measuring technical competence based on analysis of the kinematics of endovascular tool tip motions controlled with a robotic interface. We designed an experiment that recorded catheter tip movement from 21 subjects performing fundamental endovascular robotic navigation tasks on a physical model. Motion-based measures of smoothness (spectral arc length and number of submovements) were computed and tested for correlation with subjective scores from a global rating scale assessment tool that has been validated for use when performing manual catheterization. Results show that the smoothness metrics that produced significant correlations with the global rating scale for manual catheterization show similar correlations for robotic catheterization. This finding is notable, since with the robotic interface, tool tip motion is commanded discretely via a control button interface, while in manual procedures the tools are controlled through continuous movements of the surgeon's hands. Logistic regression analysis using a single motion metric was capable of classifying subjects by expertise with better than 90% accuracy. These objective and quantitative metrics that capture movement quality could be incorporated into future training protocols to provide detailed feedback on trainee performance.

Creating different learning experiences: assessment of usability factors in an interactive three-dimensional holographic projection system for experiential learning

Innovative interfaces for the display and control of information constitute an essential topic for interactive experiential learning. In this study, an interactive three-dimensional (3D) holographic projection system was developed. This system was used in a physiology-based experiential learning experiment. Learners used noncontact somatosensory methods to manipulate 3D learning objects (targets) and learned the characteristics of physiological structures in a 3D holographic projection environment. The learners did not require a physical button interface. Embodied gesture recognition was implemented in this interactive system. Furthermore, this study explored the system’s usability factors to improve the human–computer interaction and availability of the system. A total of 60 participants (30 female and 30 male) participated in a usability experiment for this 3D interactive holographic projection learning system. The participants were required to complete an interactive experiential learning task concerning the physiological structures of human organs. At the end of the task, each participant was asked to complete a questionnaire featuring 5-point Likert scales. Four crucial system usability factors were proposed through principal component analysis. These factors included ‘labelling’, ‘continuity’, ‘backlash’, and ‘ambiences’. Gender had no significant effect on any of these factors (p > 0.05). Further, the learner’s experiential learning characteristics and human–computer interaction modality are described based on the results of the usability study.

4:12 PM Abstract No. 219 Barriers to adoption of fusion and navigation tools for biopsy and ablation

To describe the different clinical systems for needle navigation and fusion image guidance for needle biopsy and ablation, and to better understand barriers to adoption. The different methodologies are described for guiding needle-based biopsy and ablation. The basic principles and differentiating mechanistic features are reviewed, as well as the workflow and clinical indications. Selected representative clinical cases are presented to demonstrate principles and barriers to adoption, such as setup processes, learning curves, complex interface buttons and sequence, cost, and workflow impact. TRUS + MRI fusion-guided prostate biopsy is used as an example to show these principles in fusion biopsy. Costs for in-MRI vs out-of-MRI biopsy are compared. Biopsy and ablation may benefit from facilitated needle navigation or multi-parametric guidance and real-time feedback. The ability to spatially combine morphometric (or anatomic) with functional (or metabolic) information may enable clinical procedures that would otherwise not be possible. Procedure time, patient throughput, equipment ergonomics, cost, and risk may be facilitated by familiarity with common barriers to adoption. Training tools to reduce learning curves include training videos, slides and bulky hardware setup flow charts. Registration hardware and techniques also differ in underlying mechanisms. These include: electromagnetic tracking, optical tracking, mechanical position sensing, stereotactics or robotics, image-based registration, and camera-on-ultrasound. Both PET and MRI data can be imported to the patient, instead of performing the procedure inside the PET or MRI environment, which can reduce cost. TRUS + MRI fusion-guided prostate biopsy hardware and software approaches demonstrate representative paradigms that differ in terms of underlying mechanisms, rationale, goals, cost, ease of use, and impact upon workflow. Many different registration and fusion systems and navigation techniques are useful for specific biopsy and ablation clinical scenarios, with variable indications, cost, ease of use, and impact on workflow. Better understanding of barriers to adoption may help realize theoretical benefits.

Retaining Human-Robots Conversation: Comparing Single Robot to Multiple Robots in a Real Event

In human-robot conversation in a real environment, low speech recognition and unnatural response generation are critical issues. Most autonomous conversational robotic systems avoid these issues by restricting user input and robot responses. However, such restrictions often render the interaction boring because the conversation becomes predictable. In this study, we propose the use of multiple robots as a solution for this problem. To explore the effect of multiple robots on a conversation, we developed an autonomous conversational robotic system and conducted a field trial in a real event. Our system adopted a button interface, which restricted user input within positive or negative intention, and maintained a conversation by choosing the most suitable of the prepared static scenarios. Through the field trial, we found that visitors who conversed with multiple robots continued their conversation for a more prolonged period, and their experience improved their impression on the conversation, in contrast to the visitors who conversed with a single robot.

Haptics of in-car radio buttons and its relationship with engineering parameters

The interaction with in-car interfaces is becoming complex and multidimensional due to the addition of more and more technologies and functionalities, which can have a negative impact on driving safety. The hand exploratory behavior of in-car interfaces has been studied aiming to minimize the mental overload of the driver when looking for radio functions. Also, the subjective and emotional values associated with the interface have been considered. However, the identification and translation of these needs into design specifications is problematic. The objective of this paper is to contribute to a better understanding of these issues by studying the relationships between users' preferences and engineering parameters of in-car radio buttons and, on the other hand, the identification of the more important engineering parameters for a better definition of the in-car interface requirements. The research was done based on an empirical study and the analysis combined exploratory statistics of preference ratings and qualitative content analysis, with partial least squares regressions and artificial neural networks to link the preferences with the buttons’ engineering parameters. Relevance to industryThis paper proposes a set of haptic engineering parameters for in-car interface buttons in order to help the manufacturers and their clients to better define interface requirements related to subjective needs of the user, and so, with a positive impact on product development costs and delays. The developed methodology can be also used in other products.

Power-free, digital and programmable dispensing of picoliter droplets using a Digit Chip.

There is a growing need for power-free methods to manipulate small volumes of liquids and thereby enable use of diagnostic assays in resource-limited settings. Most existing self-powered devices provide analog manipulation of fluids using paper, capillary or pressure-driven pumps. These strategies are well-suited to manipulating larger micro- and milliliter-scale volumes at constant flow rates; however, they fail to enable the manipulation of nanoliter and picoliter volumes required in assays using droplets, capillary sampling (e.g. finger prick), or expensive reagents. Here we report a device, termed the Digit Chip, that provides programmable and power-free digital manipulation of sub-nanoliter volumes. The device consists of a user-friendly button interface and a series of chambers connected by capillary valves that serve as digitization elements. Via a button press, the user dispenses and actuates ultra-small, quantitatively-programmed volumes. The device geometry is optimized using design models and experiments and precisely dispenses volumes as low as 21 pL with 97% accuracy. The volume dispensed can be tuned in 10 discrete steps across one order-of-magnitude with 98% accuracy. As a proof-of-principle that nanoliter-scale reagents can be precisely actuated and combined on-chip, we deploy the device to construct a precise concentration gradient with 10 discrete concentrations. Additionally, we apply this device alongside an inexpensive smartphone-based fluorescence imaging platform to perform a titration of E. coli with ampicillin. We observe the onset of bacterial death at a concentration of 5 μg mL-1, increasing to a maximum at 50 μg mL-1. These results establish the utility of the Digit Chip for diagnostic applications in low-resource environments.

Psychoacoustics of in-car switch buttons: From feelings to engineering parameters

Abstract The car interior is becoming quieter and other sounds are now exposed to user perception, such as the sound produced by interface buttons when actuated. So, the functional role of the button sound on interface operation and its aesthetic and emotional role on the user experience are now more important than before. However, little research and design effort has been paid to understand how to design buttons that produce a pleasant sound. Moreover, the button’s sound requirements received by interface manufacturers are ill-defined, insufficient or even inexistent, and consequently their conversion into specifications for manufacturing is problematic and leads to long and costly development processes. The purpose of this paper is to contribute to identify relevant acoustic parameters that explain the users sound preferences. Data on preference subjective judgments were collected and buttons acoustic signals were measured allowing the development of preference models based on partial least squares regression and neural networks methods. The former was successful in selecting the relevant parameters to describe the preference ratings of the buttons sound. The later, dealing with the non-linear nature of acoustic perception, was able to predict preferences based on the relevant parameters.

Evaluation of motion-based interaction for mobile devices: A case study on image browsing

This article evaluates the usability of motion sensing-based interaction on a mobile platform using image browsing as a representative task. Three types of interfaces, a physical button interface, a motion-sensing interface using a high-precision commercial 3D motion tracker, and a motion-sensing interface using an in-house low-cost 3D motion tracker, are compared in terms of task performance and subjective preference. Participants were provided with prolonged training over 20 days, in order to compensate for the participants’ unfamiliarity with the motion-sensing interfaces. Experimental results showed that the participants’ task performance and subjective preference for the two motion-sensing interfaces were initially low, but they rapidly improved with training and soon approached the level of the button interface. Furthermore, a recall test, which was conducted 4 weeks later, demonstrated that the usability gains were well retained in spite of the long time gap between uses. Overall, these findings highlight the potential of motion-based interaction as an intuitive interface for mobile devices.
