Robotic surgery

AbstractBackgroundProficiency in minimally invasive surgery requires intensive and continuous training, as it is technically challenging for unnatural visual and haptic perceptions. Robotic and computer sciences are producing innovations to augment the surgeon's skills to achieve accuracy and high precision during complex surgery. This article reviews the current use of robotically assisted surgery, focusing on technology as well as main applications in digestive surgery, and future perspectives.MethodsThe PubMed database was interrogated to retrieve evidence-based data on surgical applications. Internal and external consulting with key opinion leaders, renowned robotics laboratories and robotic platform manufacturers was used to produce state-of-the art business intelligence around robotically assisted surgery.ResultsSelected digestive procedures (oesophagectomy, gastric bypass, pancreatic and liver resections, rectal resection for cancer) might benefit from robotic assistance, although the current level of evidence is insufficient to support widespread adoption. The surgical robotic market is growing, and a variety of projects have recently been launched at both academic and corporate levels to develop lightweight, miniaturized surgical robotic prototypes.ConclusionThe magnified view, and improved ergonomics and dexterity offered by robotic platforms, might facilitate the uptake of minimally invasive procedures. Image guidance to complement robotically assisted procedures, through the concepts of augmented reality, could well represent a major revolution to increase safety and deal with difficulties associated with the new minimally invasive approaches.

Development of Color Vision Deficiency Assistive System

Color vision deficiency is commonly known as color blind, is a type of vision defect in our eyeball. The inability to recognize color has caused several problems to the patient daily life and in conducting certain color oriented activities. To help the patient cope with the problem of recognizing colors, a color vision deficiency aided device is designed. This paper focuses on developing a user interface that can detect colors and show it as text on the screen of the device using the concept of augmented reality. The system basically consists of a mini computer, Raspberry PI and its own camera module as well as a LCD screen for display purposes. Raspberry PI is used due to its small and compact size and capability to carry out image processing. With the help of OpenCV library, color detection, filtering and processing can be carried out easily. Benchmark shape and color of has been designed for experimental purposes to test for the performance and functionality of the system. The result of the distance test shows that the hue (H) element is almost consistent whereas the saturation (S) varies by roughly 49.3% and value (V) by 30.5%. As for the range of detection, the minimum range is 12 cm where the maximum range is up to 15 meter. The accuracy of the 4 base colors detection is about 80%.

Towards Measuring Learning Effectiveness considering Presence, Engagement and Immersion in a Mixed and Augmented Reality Learning Environment

The current era of advanced display technologies, such as a head mounted displays, smart glasses and handheld devices, have supported the usage of mixed-reality and augmented reality concepts in smart educational classrooms. These advanced technologies have enabled enhanced collaboration and an interactive communication between distance learners and local learners. Being present' is a key factor in both worlds (real and virtual) as it plays an important role in increasing the students' collaborative engagement during the learning activity. However, few studies have considered how much using such immersive interfaces with various learning scenarios may ultimately affect learning outcomes, and whether students feel fully engaged or not in such environments. This work-in-progress paper will demonstrate a MiRTLE+ prototype of how remote students can collaborate within mixed-reality environments by using an augmented reality approach. Secondly, it will explore the learning effectiveness based on the following factors: students' presence, engagement, and immersion in smart environments. With regard to the learning task, we will consider a card game task to measure the learners' progress as they progress from novice to expert player. To evaluate these factors, we utilise several existing frameworks which have been applied to our mixed-reality worlds that help us to examine the learning outcomes from using these environments.

Visual Assembling Guidance Using Augmented Reality

This paper describes a study of using the concept of augmented reality for supporting assembly line workers in carrying out their task optimally. By overlaying virtual information on real world objects – and thereby enhance the human's perception of reality – augmented reality makes it possible to improve the visual guidance to the workers. In the study, a prototype system is developed based on the Oculus Rift platform and evaluated using a simulated assembling task. The main aim is to investigate user acceptance and how this can possible be improved.

Designing take over scenarios for automated driving

Highly automated driving allows the driver to temporarily turn away from the driving task, meaning he or she does not have to monitor the system. This leads to the challenge of getting the driver back into the loop, if the automation reaches a system boundary. This study investigates, whether augmented reality information can positively influence the take over process. Therefore we evaluated two augmented reality concepts. The concept “AR red” displays a corridor on the road to be avoided by the driver in a take over scenario. The concept “AR green” suggests a corridor the driver can safely steer through. Results indicate that the type of augmented reality information does not influence take over times, but considerably affects reaction type. Visual inspection revealed higher consistency in driving trajectories for participants following the proposed corridor of “AR green” concept as compared to trajectories of drivers confronted with the restricted zone of “AR red”.

Melhorar a atratividade da informação através do uso da realidade aumentada

Propomo-nos neste trabalho abordar o conceito de realidade aumentada e as suas aplicações no contexto de aprendizagem, nomeadamente, para explicar um conceito através da incorporação de dados ao objecto captado por um dispositivo móvel. A técnica consiste em analisar imagens-chave na foto ou a própria posição geográfica do usuário e combiná-las, através de uma aplicação informática, com dados armazenados e que se sobrepõem à realidade. Esta técnica desafia a tarefa clássica no quadro tradicional. Com ela, pretende-se rendibilizar, do ponto de vista informacional e educativo, o fenómeno alargado do uso de dispositivos móveis pois, observamos que estas tecnologias avançadas motivam o utilizador a explorar determinadas áreas do conhecimento. Este tipo de trabalho aplica-se a etapas educativas indefinidas pois, actualmente, prolonga-se, ao longo da vida, os momentos em que se adquire formação. Os âmbitos de utilização também não são específicos e dissipam-se, dado que a referência espacial está se deslocando para um campo virtual de indefinição física e num contexto dominado pelo próprio usuário.

Exploring the Affective Museum Visiting Experience: Adaptive Augmented Reality (A2R) and Cultural Heritage

Providing engaging interpretation resources for museum and gallery visitors may have a great impact on the overall museum visiting experience all by assisting museums in maintaining long-term relationships with their public. This paper focuses on the ways through which AR can be employed in museum and gallery settings as an interpretation medium. It also introduces a new generation of multimedia guides for the museum visit inspired by the concept of Adaptive Augmented Reality (A2R). Adaptive Augmented Reality (A2R) provides visual and acoustic augmentations that come to supplement the artefact or site viewed by a museum or gallery visitor and monitors the cognitive and affective impact of all interactions of the museum visitor both with the physical and the digital environment. The ultimate goal is to make every museum visit unique, by tailoring an Augmented Reality visit with contents that are susceptible to increase the affective impact of the augmented museum visiting experience and hence encourage intrinsic and self-motivated learning.

Ubiquitous Mobile Real Time Visual Translator Using Augmented Reality for Bahasa Language

 Abstract—Mobile technology have rapidly advanced over the years, successful researches of augmented reality on mobile phones under the different mobile platforms have made it possible to implement augmented reality technology on mobiles. Now the possibility of combining real time visual with augmented reality seems to be a success. This paper is simply to emphasize on combining real time visual with augmented reality technology on mobiles for education purpose. The research is based on how the implementation of real time visual translator on augmented reality mobile applications can help people in understanding/translating and give meanings to some writings displayed around them ubiquitously.  possible new kind of applications that manipulate the person's surrounding perspective. AR systems combine virtual information into a person's physical environment so that he or she will observe that information as existing in their surroundings. Mobile augmented reality systems (MARS) provide this service without limiting the individual's location to a specially equipped area. Augmented Reality (AR) is currently being used in disciplines of computer science (visualization, robotics, nanotechnology), engineering, applied psychology, education, environmental design, medicine, engineering, tourism, and archaeology. The use of mobile phone is the perfect liberation medium for learning in near future. The concept of augmented reality seems to be succefully implemented on mobiles and by combining Mobile Augmented reality, real time rendering and ubiquitous; the idea is to develop a real time translator that will translate Bahasa language to English language and give meanings of the words translated, anywhere to any environment whenever desired (ubiquitous). This application is mostly based on education that is providing or diverting knowledge to people who actually need it (4), (5).

MARble – Augmented Reality in Medical Education

The use of eLearning content to improve teaching and learning has a long-standing tradition in medical education. Nevertheless, “old fashioned” eLearning modules for medical subjects often lack a level of experience that is only possible with bedside teaching. On the other hand, bedside teaching may not always be a possibility, e.g. due to restrictions in time and place, since cases that allow the presentation of certain findings are not always available. Another aspect is that not all cases may be used in an appropriate manner for teaching purposes due to ethical constraints. For visually oriented subjects, Augmented Reality (AR) based applications can offer a way out of this dilemma since they make it possible to build almost life-like virtual cases that show all desired aspects and have the potential to significantly enhance the learning experience. Due to the ubiquitous availability of mobile phones and tablets and their ever-increasing computing power, it seems feasible to implement the concept of augmented reality on mobile devices. mARble®, an Augmented Reality powered learning environment for mobile phones based this concept, will be presented in this paper. Currently, content for a basic course in legal medicine is available; a preliminary evaluation has been performed to evaluate the concept regarding its effect on the learning experience. First results will be presented.

Acoustically aided HMI for ROV navigation

Majority are ROVs underwater vehicles with relatively slow dynamics virtually providing a ROV pilot extra time to perform other tasks, such as inspections and arm operation. However, with many tasks performed simultaneously with flying the relevant information is typically dispersed on a number of screens overloading the pilot's visual channel. Therefore, mishaps are likely to occur. To improve pilots’ perception of its surroundings and to unload their visual channel, a new method called AD AR (Audio Augmented Reality) which combines the concept of Augmented Reality with virtual audio-video user interface, is proposed. In this paper, the feasibility of proposed method used as an aiding tool for navigation is investigated. All experiments are performed on the state-of-the-art, realistic ROV simulator developed by Mobile & Marine Robotics Research Centre, ECE Department, University of Limerick, Ireland.

A Case Study of Augmented Reality for Mobile Platforms

This work describes the proposal of an architecture that evolves the concept of augmented reality with geolocation to mobile device platforms. The architecture allows the development of applications that draw points of interest on screen, represented by arrows and panels that directs to each point of interest's location. It uses OpenGL ES 1.0 library to draw the points of interest. The applications' user interaction can be made by moving the device in such a way that activates compass and accelerometer sensors. The device's location determines how far are the points of interest. This work also presents development resources that allow developers to use camera, sensors and geographic coordinates on applications inside the devices simulators. At the end we present an application example along with performance results running on an Android platform's simulator and also on a Android device.

Perceptual Effects in Aligning Virtual and Real Objects in Augmented Reality Displays

The concept of Augmented Reality (AR) displays is defined, in relation to the amount of real (unmodelled) and virtual (modelled) data presented in an image, as those displays in which real images, such as video, are enhanced with computer generated graphics. For the important class of stereoscopic AR displays, several factors may cause potential perceptual ambiguities, however, which manifest themselves in terms of decreased accuracy and precision whenever virtual objects must be aligned with real ones. A review is given of research conducted to assess both the magnitude of these perceptual effects and the effectiveness of a computer assisted Virtual Tape Measure (VTM), which has been developed for performing quantitative 3D measurements on real-world stereo images.
