Many elderly and disabled people are prevented from using Assistive technology effectively because of difficulties in identifying suitable interface devices (e.g. switches, joysticks or haptic devices). The overall objective of this proposal is to develop and exploit a system for selecting an optimum interface controller for users of assistive technology. The work will involve the establishment of User Groups to define required systems and to ensure end products meet their needs.
The technical programme will develop:
a system to characterise existing interfaces,
and a VR simulator integrated with a haptic interface to quantify user abilities for the operation of different interfaces. There will be exploitation of the I-Match system, development of services to manufacturers and a database for use by service providers.
DESCRIPTION OF WORK
Many people with disabilities rely upon assertive technology for independence. However, in many cases, the potential of a particular piece of technology is restricted by the difficulties of user operation. i.e. the impairments which lead to the recommendation of a device prevent its very operation because of the difficulties of interfacing with the user. This project concentrates on the development of techniques to optimise the selection of an interface for a user by measuring both the functional characteristics of the device (e.g. joystick, switch, mouse etc) and the skills of the user.
The key activities are as follows:
to define and measure physical and functional characteristics of available interfaces;
the resulting data will be put into a publicly available database for use by providers and users to measure the hand and arm skills of users. This will involve development of simulations of devices to be controlled (e.g. powered wheelchairs, rehabilitation robots, computers).
It will be possible to operate this system with any type of interface (including a haptic device). Using a set of exercises and tests, it will allow quantification of the abilities of users and, therefore, choice of the optimum interface. The use of a haptic interface with the system will allow the identification of user skills in response to more sophisticated force feedback.
The system will be evaluated by User Centres in 4 different member states. Studies will be designed to ensure rigorous evaluation of this approach to interface selection and user training. Exploitation of VR systems and associated techniques will be handled by a Consortium of EU companies experienced in software and rehabilitation robotics.
