An assistance system for visually handicapped persons with visual impairment in a part of their visual field includes body-worn sensors to inform them actively about objects or movements in the visually impaired sides.

System for inducing a subject to fall to sleep

A system for inducing a subject to fall to sleep includes a light pattern generator for generating a time varying light pattern in view of the subject. Further, the system includes a breathing rate measuring unit for measuring a breathing frequency of the subject. In addition, the system includes a control unit connected to the breathing rate measuring unit and the light pattern generator, for controlling the light pattern generator such that the generated light pattern has a pattern frequency substantially between the measured breathing frequency and a pre-selected desired frequency.

A method for post-synchronizing information stream includes obtaining lip-objects from a video signal. The original lip-objects are replaced with new lip-objects which correspond to a translated audio signal. The new lip-objects may be obtained by tracking a further video signal or by using a database with visemes or lip-parameters. For a multi-language information stream, a desired language may be selected at the receiver.

Post-synchronizing an information stream including lip objects replacement

The invention provides a method for post-synchronizing an information stream. Original lip-objects (lo) are obtained ( ) from a video signal (V). These original lip-objects (lo) are replaced ( ) with new lip-objects (lo*), which correspond to a translated audio signal (A*). Lip-objects (lo) can be obtained from the video signal (V) by using an object-oriented coding technique, e.g. MPEG-4. The coding standard MPEG-4 offers the facilities to manipulate the lip-objects (lo). Several configurations are presented. The new lip-objects (lo*) can be obtained by tracking a further video signal or by using a database with visemes or lip-parameters. The invention is suitable for a communication network, e.g. for video-conferencing. A multi-language information stream comprises a plurality of audio signals (A,A*) and a plurality of lip-objects (lo,lo*) that are each linked to one of the audio signals (A,A*). This gives the possibility to select at the receiver a desired language. An advantage of the invention is that lip-movements better correspond to the translated audio.
