Goal Development of generic tools allowing interconnection of home networking protocols & Internet protocol (IP: Internet Protocol) to favor integration of assistive aids at homes of people with disabilities.

Smart Home project: Innovated Action financed by GET &Louis Leprince Ringuet Foundation

Target Integration of assistive technologies in the context of smart environment “Smart homes” for people having severe motor disabilities.

Software Architecture

Input devices

Manipulation Robotics systems to compensate objects manipulation functions (gripping objects, drinking, eating, inserting a tape in VCR, etc..)

Communication Communication systems Designed for persons who lost communication possibilities.These systems allow translating physical actions into vocal or written synthesis

DomoticsTechnologies for new services at homes with environmental control systems facilitate accessibility to the environment and to the home equipments (open window, pickup telephone, television command…)

Computer accessComputer applications Giving to persons with disabilities more services which could be a helpful in their daily life, such as Internet access and associated applications, software access (text processing) and also other specific applications bind to smart homes and robotics

Users needs Analysis This research activity concern

mainly the use of assistive technological systems by people with motor disabilities and elderly people

in daily practice situations. Some experimentations involving visual impaired people are also planned.

This study is based primarily on a

evaluation method through an investigation of the users needs and

also through experts recommendations, by the use of

dedicated questionnaires and scenarios carried out within the framework of

this project

Questionnaires dedicated to:• Users with motor disabilities• Experts in motor handicap• Users with visual impairments • Experts Visual handicap• Elderly users people • Experts in Elderly users

•Person's with motor disabilities •Investigations are carried out on various places: Garches hospital in Paris and AFM (French Muscular Dystrophies Association) in Evry• In 2002, 28 persons participated to experimentations.

Users

Configuration tool - Choice of input devices- Configuration & adaptation of input devices according to each user - Easy actions distribution (output interfaces) on different ActionMaps- Communications Protocols with supervisor- Easy upgrading of software modules

Wireless communication protocols: Bluetooth Protocol

Features:• Speed: 721 Mbps• Scalability: easy to expand and to include new devices (medical

equipment, patient’s palm pilot etc).• Flexibility: Instant network, conference anywhere.• Security: Identification of each Bluetooth device is unique.• Low cost of ownership: no wires, lower costAdvantages:• Low power consumption.• Secure, as each Bluetooth product has a unique identification.• Flexible in adding new devices, hence good for later additions to the

system.• Does not require line-of-sight.• Low cost.Disadvantages:• Low speed for our application.• Need to develop interface to browse from port.• Not widely used with PC to PC communication.

Mobility Electric wheelchairs and adapted cars allowing the compensation of moving function inside or outside of buildings

Power Lines Communication protocols: X2D• Protocol to control electrical units • Need special receptor and transmitter unit• Use of modem X2D for data transmission • The X2D modules should be configured (address attribution)

Infra red communication Protocol: IrDa Protocol Features:•Speed: 115.2 kbps, diffused IrDA gives lower speed. •Scalability: cannot scale easily to communicate with multiple hosts.•Flexibility: instant network, conference anywhere.•Security: line-of-sight (also diffused), cannot penetrate walls. •Low Cost of Ownership: no wires, lower cost.Advantages:•Secure, does not penetrate walls.•Can easily communicate with peripheral devices, like printers.•Low cost and can be used to transfer information from the Tablet PC to another PC.Disadvantages:•Low speed.•Line-of-sight required, diffused IrDA available, but not very popular.•Very small range of coverage.•Generally used for communication with peripherals and not for networking PCs
