Operation of the human-machine interface

Universal human-machine interface for people with disabilities

Most assistive devices for people with disabilities are highly specialised: each one supports only a limited number of impairments. Generally, each person with a disability needs to acquire several of these systems to compensate for his or her disability(ies).

It is noted that :

  • They are manufactured in small series, which leads to high costs and maintenance difficulties,
    that the potential of current information processing systems is still largely under-exploited in this field.
  • The project consisted of defining, developing and validating a virtually universal assistance system based on widely available hardware.

The system must first and foremost ensure a two-way dialogue with the user, regardless of the latter’s disability(ies). It therefore incorporates a universal human-machine interface characterised by the following points:

  • navigation in the menus and activation of the commands whatever the selected input-output interfaces,
  • configuration by the user’s entourage (or by the user in some cases), – automatic detection of available peripherals,
  • automatic detection of available peripherals, – contextual assistance, depending on the location or current activity.

The HMI interface developed within the framework of the project also supports a number of assistance functions:

  • Sending commands: remote switching on and off of devices,
  • telecommunications: telephone (mobile phone), SMS etc,
  • IR remote control of HiFi devices, televisions etc,
  • Support for specialised systems, e.g. Braille keyboard/display.

The software is designed in such a way that additional functions can be easily integrated (open and upgradeable system). It can be maintained to a large extent remotely (remote diagnosis and remote maintenance).
