Designing for long-term human-robot interaction and application to weight loss
Thesis (Ph. D.)--Massachusetts Institute of Technology, School of Architecture and Planning, Program in Media Arts and Sciences, 2008.Includes bibliographical references (p. 241-251).Human-robot interaction is now well enough understood to allow us to build useful systems that can function outside of the laboratory. This thesis defines sociable robot system in the context of long-term interaction, proposes guidelines for creating and evaluating such systems, and describes the implementation of a robot that has been designed to help individuals effect behavior change while dieting. The implemented system is a robotic weight loss coach, which is compared to a standalone computer and to a traditional paper log in a controlled study. A current challenge in weight loss is in getting individuals to keep off weight that is lost. The results of our study show that participants track their calorie consumption and exercise for nearly twice as long when using the robot than with the other methods and develop a closer relationship with the robot. Both of these are indicators of longer-term success at weight loss and maintenance.by Cory David Kidd.Ph.D
New applications for phosphoric acid fuel cells
New applications for phosphoric acid fuel cells were identified and evaluated. Candidates considered included all possibilities except grid connected electric utility applications, on site total energy systems, industrial cogeneration, opportunistic use of waste hydrogen, space and military applications, and applications smaller than 10 kW. Applications identified were screened, with the most promising subjected to technical and economic evaluation using a fuel cell and conventional power system data base developed in the study. The most promising applications appear to be the underground mine locomotive and the railroad locomotive. Also interesting are power for robotic submersibles and Arctic villages. The mine locomotive is particularly attractive since it is expected that the fuel cell could command a very high price and still be competitive with the conventionally used battery system. The railroad locomotive's attractiveness results from the (smaller) premium price which the fuel cell could command over the conventional diesel electric system based on its superior fuel efficiency, and on the large size of this market and the accompanying opportunities for manufacturing economy

How a Diverse Research Ecosystem Has Generated New Rehabilitation Technologies: Review of NIDILRR’s Rehabilitation Engineering Research Centers
Over 50 million United States citizens (1 in 6 people in the US) have a developmental, acquired, or degenerative disability. The average US citizen can expect to live 20% of his or her life with a disability. Rehabilitation technologies play a major role in improving the quality of life for people with a disability, yet widespread and highly challenging needs remain. Within the US, a major effort aimed at the creation and evaluation of rehabilitation technology has been the Rehabilitation Engineering Research Centers (RERCs) sponsored by the National Institute on Disability, Independent Living, and Rehabilitation Research. As envisioned at their conception by a panel of the National Academy of Science in 1970, these centers were intended to take a “total approach to rehabilitation”, combining medicine, engineering, and related science, to improve the quality of life of individuals with a disability. Here, we review the scope, achievements, and ongoing projects of an unbiased sample of 19 currently active or recently terminated RERCs. Specifically, for each center, we briefly explain the needs it targets, summarize key historical advances, identify emerging innovations, and consider future directions. Our assessment from this review is that the RERC program indeed involves a multidisciplinary approach, with 36 professional fields involved, although 70% of research and development staff are in engineering fields, 23% in clinical fields, and only 7% in basic science fields; significantly, 11% of the professional staff have a disability related to their research. We observe that the RERC program has substantially diversified the scope of its work since the 1970’s, addressing more types of disabilities using more technologies, and, in particular, often now focusing on information technologies. RERC work also now often views users as integrated into an interdependent society through technologies that both people with and without disabilities co-use (such as the internet, wireless communication, and architecture). In addition, RERC research has evolved to view users as able at improving outcomes through learning, exercise, and plasticity (rather than being static), which can be optimally timed. We provide examples of rehabilitation technology innovation produced by the RERCs that illustrate this increasingly diversifying scope and evolving perspective. We conclude by discussing growth opportunities and possible future directions of the RERC program
Augmented Human Assistance (AHA)
Aging and sedentarism are two main challenges for social and health
systems in modern societies. To face these challenges a new generation of ICT
based solutions is being developed to promote active aging, prevent sedentarism
and find new tools to support the large populations of patients that suffer chronic
conditions as result of aging. Such solutions have the potential to transform
healthcare by optimizing resource allocation, reducing costs, improving diagno ses and enabling novel therapies, thus increasing quality of life.
The primary goal of the “AHA: Augmented Human Assistance” project is to de velop novel assistive technologies to promote exercise among the elderly and
patients of motor disabilities. For exercise programs to be effective, it is essential
that users and patients comply with the prescribed schedule and perform the ex ercises following established protocols. Until now this has been achieved by hu man monitoring in rehabilitation and therapy session, where the clinicians or
therapists permanently accompany users or patient. In many cases, exercises are
prescribed for home performance, in which case it is not possible to validate their
execution. In this context, the AHA project is an integrative and cross-discipli nary approach of 4 Portuguese universities, the CMU, and 2 Portuguese industry
partners, that combines innovation and fundamental research in the areas of hu man-computer interaction, robotics, serious games and physiological computing
(see partner list in Appendix A). In the project, we capitalize on recent innova tions and aim at enriching the capabilities and range of application of assistive
devices via the combination of (1) assistive robotics; (2) technologies that use
well-understood motivational techniques to induce people to do their exercises in
the first place, and to do them correctly and completely; (3) tailored and relevant
guidance in regard to health care and social support and activities; and (4) tech nologies to self-monitoring and sharing of progress with health-care provider enabling clinicians to fine-tune the exercise regimen to suit the participant’s ac tual progress.
We highlight the development of a set of exergames (serious games controlled
by the movement of the user’s body limbs) specifically designed for the needs of
the target population according to best practices in sports and human kinetics
sciences. The games can be adapted to the limitations of the users (e.g. to play in
a sitting position) so a large fraction of the population can benefit from them. The
games can be executed with biofeedback provided from wearable sensors, to pro duce more controlled exercise benefits. The games can be played in multi-user
settings, either in cooperative or competitive mode, to promote the social rela tions among players. The games contain regional motives to trigger memories
from the past and other gamification techniques that keep the users involved in
the exercise program. The games are projected in the environment through aug mented reality techniques that create a more immersive and engaging experience
than conventional displays. Virtual coach techniques are able to monitor the cor rectness of the exercise and provide immediate guidance to the user, as well as
providing reports for therapists. A socially assistive robot can play the role of the
coach and provide an additional socio-cognitive dimension to the experience to
complement the role of the therapist. A web service that records the users’ per formances and allows the authorized therapists to access and configure the exer cise program provides a valuable management tool for caregivers and clinical
staff. It can also provide a social network for players, increasing adherence to the
therapies.
We have performed several end-user studies that validate the proposed ap proaches. Together, or in isolation, these solutions provide users, caregivers,
health professionals and institutions, valuable tools for health promotion, disease
monitoring and prevention.info:eu-repo/semantics/publishedVersio

Emergent AI, Social Robots and the Law: Security, Privacy and Policy Issues
The rapid growth of AI systems has implications on a wide variety of fields. It can prove to be a boon to disparate fields such as healthcare, education, global logistics and transportation, to name a few. However, these systems will also bring forth far-reaching changes in employment, economy and security. As AI systems gain acceptance and become more commonplace, certain critical questions arise: What are the legal and security ramifications of the use of these new technologies? Who can use them, and under what circumstances? What is the safety of these systems? Should their commercialization be regulated? What are the privacy issues associated with the use of these technologies? What are the ethical considerations? Who has responsibility for the large amounts of data that is collected and manipulated by these systems? Could these systems fail? What is the recourse if there is a system failure? These questions are but a small subset of possible questions in this key emerging field. In this paper, we focus primarily on the legal questions that relate to the security, privacy, ethical, and policy considerations that emerge from one of these types of technologies, namely social robots. We begin with a history of the field, then go deeper into legal issues, the associated issues of security, privacy and ethics, and consider some solutions to these issues. Finally, we conclude with a look at the future as well as a modest proposal for future research addressing some of the challenges listed
