Paper Abstract:
|
Sign language was developed due to the need for people with significant hearing impairment to communicate. This visual
language replaces the oral language in deaf community. This paper presents a system which allows the translation from
Spanish written language to Spanish animated Sign Language by means of a virtual interpreter. Most of the existing
approaches do not produce satisfactory results because of the unrealistic movements and the dependence on the
visualization device, which is usually a high-end workstation. The architecture proposed in GANAS uses an highly
accurate internal representation of the movements (hands, arms, facial expressions...) needed for the deaf community to
express and understand thoughts. This representation is independent of the virtual character and it can be easily reused for
other systems. Non Linear Animation techniques are used to blend the timeline of each animation layer. The results of the
representation phase can be adapted to be suitable for the use in different representation devices such as computers,
mobile phones, PDAs, etc. In order to reduce the processing time, the 3D rendering can be performed in the own device
or in a parallel way by using a P2P approach. |
