Abstract

User-centered design (UCD) facilitates the creation of technologies that are specifically designed to answer users’ needs. This paper presents the first step of a UCD using a persona, a fictitious character representing the targeted population, which in this case is people having sustained a traumatic brain injury (TBI). The persona is used to better understand the possible interactions of a TBI population with a prototype of a technology that we wish to develop, namely the Cognitive Orthosis for coOKing (COOK). COOK is meant to be an assistive technology that will be designed to promote independence for cooking within a supported-living residence. More specifically, this paper presents the persona’s creation methodology based on the first four phases of the persona’s lifecycle. It also describes how the persona methodology served as a facilitator to initiate an interdisciplinary collaboration between a clinical team and a computer science team. Creation of personas relied on a clinical model (Disability Creation Process) that contextualized the needs of this population and an evaluation tool [Instrumental Activities of Daily Living (IADL) Profile] that presented a wide range of cognitive assistance needs found in this same population. This paper provides an in-depth description of some of the most frequent everyday difficulties experienced by individuals with TBI as well as the persona’s abilities, limitations and social participation during the realization of IADL, and an evaluation of the manifestations of these difficulties during IADL performance as represented through scenarios. The interdisciplinary team used the persona to complete a first description of the interactions of a persona with TBI with COOK. This work is an attempt at offering a communication tool, the persona, to facilitate interdisciplinary research among diverse disciplines who wish to learn to develop a common language, models and methodologies at the beginning of the design process.

Abstract

The rising number of the elderly incurs growing concern about healthcare, and in particular rehabilitation healthcare. Assistive technology and assistive robotics in particular may help to improve this process. We develop a robot coach capable of demonstrating rehabilitation exercises to patients, watch a patient carry out the exercises and give him feedback so as to improve his performance and encourage him. The HRI of the system is based on our study with a team of rehabilitation therapists and with the target population.The system relies on human motion analysis. We develop a method for learning a probabilistic representation of ideal movements from expert demonstrations. A Gaussian Mixture Model is employed from position and orientation features captured using a Microsoft Kinect v2. For assessing patients' movements, we propose a real-time multi-level analysis to both temporally and spatially identify and explain body part errors. This analysis combined with a classification algorithm allows the robot to provide coaching advice to make the patient improve his movements. The evaluation on three rehabilitation exercises shows the potential of the proposed approach for learning and assessing kinaesthetic movements., Comment: IRC 2018 : Second IEEE International Conference on Robotic Computing, Jan 2018, Laguna Hills, CA,, United States

Abstract

International audience; Habits characterize the activities of elderly people. Monitoring their habits and their ability to carry out the activities of daily living is a great challenge in order to improve aging at home. In particular, the detection of changes in regular behavior may help to detect emerging disorders. The emergence of smart homes and sensor networks allow the non-intrusive collection of data describing the activities in the home. The collected data is indeed an objective source to mine periodic patterns representing the habits of a particular individual. Extended Episode Discovery (xED) algorithm is described and discussed. This algorithm searches for regular patterns, highlighting the periodicity and variability of each discovered pattern. This approach allows a high adaptability to different users and lifestyles. Experiments on six real-life datasets illustrate the interest of xED.

Abstract

International audience; This short paper compares two approaches of the state of the art, to implement Ambient Assisted Living (AAL) systems. By com- paring the two approaches, we aim to show that combining them could lead to an improvement of the offered response of the system. It shows that it could be interesting to develop a proof-of-concept system from a combination of these approaches, as it would improve the state of the art in AAL systems.

Abstract

International audience; In the next decades, the growth in population ageing will cause important problems to most industrialized countries. To tackle this issue, Ambient Assistive Living (AAL) systems can reinforce the well-being of elderly people, by providing emergency, autonomy enhancement, and comfort services. These services will postpone the need of a medicalized environment, and will allow the elderly to stay longer at home. However, each elderly has specific needs and a deployment environment of such services is likely unique. Furthermore, the needs evolve over time, and so does the deployment environment of the system. In this paper, we propose the use of a model-based development method, the adaptive medium approach, to enable dynamic adaptation of AAL systems. We also propose improvements to make it more suited to the AAL domain, such as considering heterogeneity and a composition model. The paper includes an evaluation of the prototype implementing the approach, and a comparison with related work.

Abstract

International audience; One of the biggest challenges we currently face is to keep elderly people immersed in their social environment when they leave their home and enter a retirement home. Many of them feel isolated. The TV stands as their favorite media, and our first experiments showed that listening to vocalized local news and receiving TV messages and photos from family helped in fighting these feelings of isolation. With online social networks, we wish to involve the elderly in new types of interactions, more various and frequent. They will be more active and included in micro-conversations around multimedia contents. The retirement homes will benefit also from social networking capabilities. They will participate to the local news dedicated to the elderly people. In addition, the remote family will be informed of activities through an agenda and various publications.

Abstract

In this paper we propose a solution for integrating two neural networks which are used for handwritten digit recognition. As with the human brain structure, we have chosen to send global information to the first network and to send a sequence of local information to the second network. The first neural network uses digits as images. The second neural network uses digits as contours. One strategy is described for combining these neural networks. We show that we can obtain much better results from a combination of neural network than from individual neural networks.

Abstract

People with disabilities need several assistive technical aids to increase their autonomy and perform daily living tasks. This paper describes the role of networking and communication in the smart home concept which allows people with disabilities and elderly people to retain a certain level of independence within their daily environment, such as at home, work, school, outside and so on. The purpose of our research activity is to explore the difficulties by determining the most suitable approach to federate the different communication protocols available indoor and outdoor environments. In this paper we are presenting our main concept in the design of the smart home architecture. We also describe our approach to design an open software environment adapted to people with disabilities. This approach is based on the service discovery protocol UPnP (Universal Plan and Play) to discover devices in smart home. It is based also on wireless technologies and protocols (Wifi, Bluetooth, etc.) to enhance mobility and dependency. Some solutions are adapted to favor integration of new modules and devices, and to improve the communication between the different layers of our software architecture.

Abstract

This paper presents neural and hybrid (symbolic and subsymbolic) applications downloaded on the distributed computer architecture ArMenX. This machine is articulated around a ring of FPGAs acting as routing resources as well as fine grain computing resources and thus giving great flexibility. More coarse grain computing resources-Transputer and DSP-tightly coupled via FPGAs give a large application spectrum to the machine, making it possible to implement heterogeneous algorithms efficiently involving both low level (computing intensive) and high level (control intensive) tasks. We first introduce the ArMenX project and the main architecture features. Then, after giving details on the computing of propagation and back-propagation of the multi-layer perceptron on ArMenX, we will focus on a handwritten digit (issued from a zip code data base) recognition application. An original and efficient method, involving three neural networks, is developed. The first two neural networks deal with the 'reading process', and the last neural network, which learned to write, helps to make decisions on the first two network outputs, when they are not confident. Before concluding, the paper presents the work of integration of ArMenX into a high level programming environment, designed to make it easier to take advantage of the architecture flexibility.

Abstract

The computation power needed in communication and image processing is increasing so much that parallel architecture can be seen as the only solution available. Serious drawbacks of such architectures are their lack of flexibility and the complexity of their programming. The goal of the ArMenX project is to offer a flexible development and prototyping platform for signal and image parallel processing. The ArMenX architecture consists of a set of replicated processing nodes. Each node consists of three tightly coupled units: a Transpute, a FPGA, and a DSP. The ArMenX nodes are interconnected by two media: one is an asynchronous serial link, and the other is a high bandwidth parallel ring. Thanks to this flexible multi-DSP architecture, ArMenX allows efficient implementation of a 'large kind of algorithms' involved in signal and image processing. We will present three examples of working applications on this parallel architecture: a parallel forward and backward propagation for neural network; a parallel implementation of computing an electromagnetic field (for an electrostatic and magnetostatic probelm) using an artificial neural network; and a large image compression algorithm using wavelet transform. The present work deals with the integration of a high level programming neural network environment. This environment will make it easier to take advantage of this architecture's flexibility.© (1995) COPYRIGHT SPIE--The International Society for Optical Engineering.

Abstract

We first show how systems coupling symbolic methods with sub-symbolic ones -the so-called hybrid systems- can solve efficiently problems by using advantages from the two types of methods. Then we present a new flexible multi-grain parallelism architecture, called ArMenX, and we show how hybrid systems can be executed on this machine.
