- There is a growing need in recent years for products with high usability. Conventionally, researchers have only focused on the interactions between user and device in carrying out user tests. We have premised our research, however, on the assumption that there exist two users in the use of robotic assistive devices: a frail person, such as an elderly person who needs care, and the caregiver who provides support. As an approach to making a video analysis of a user test, we propose a methodology that focuses on the perspectives of these two users. We used behaviour analysis to compare two videos: one showing a frail elderly person being fed by a caregiver and the other showing the same person eating food on their own with the help of a robotic assistive device. Our finding based on these videos was that the robotic assistive device reduces the burden of caregivers and increases the quality of life (QOL) of the elderly. Also, we discovered that this methodology using video analysis is useful in pinpointing improvements that can be made in the device.

- This project aims at making a mock-up of a multigrip tool for a robotic assistive device and a camera systemwhich enable frail elderly to live more independently and tokeep track of their food intake. The robot will be developedthrough user centred design with analyses of real use cases inJapan and Sweden. Thanks to the collaborating researcherswith a strong applied research approach as well as thecompanies with a strong experience in engineering solutionsin both the Japanese and Swedish teams, the functionalities ofBestic, an assistive eating device, could be enhanced forcommercial use, and distributed to municipalities and to thegeneral public

- Ageing is becoming an increasingly major problem in European and Japanese societies. We have so far mainly focused on how to improve the eating experience for both frail elderly and caregivers by introducing and developing the eating aid robot, Bestic, made to get the food from plate to the mouth for frail elderly or person with disabilities. We expand the functionalities of Bestic to create food intake reports automatically so as to decrease the undernutrition among frail elderly and workload of caregivers through collecting data via a vision system connected to the Internet of Things (IoT) system. Since the computation capability of Bestic is very limited, computation offloading, in which resource intensive computational tasks are transferred from Bestic to an external cloud server, is proposed to solve Bestic’s resource limitation. In this paper, we proposed a Monte Carlo algorithm based heuristic computation offloading algorithm, to minimize the total overhead of all the Bestic users after we show that the target optimization problem is NP-hard in a theorem. Numeric results showed that the proposed algorithm is effective in terms of system-wide overhead.
