Patent attributes
A facial feature analysis system for command applications for users with physical disabilities, like impaired users of wheelchairs, patient beds or other appliances is provided. The disclosed system includes a virtual filter bank and a virtual discriminator. The virtual filter bank comprises a feature localization main module having an ancillary data bank which supplies a special signal Sg for control functions. The system calculates face localization based on parameters of a holistic face-model, calculates feature localization based on parameters of an adaptive face graph, calculates feature extraction using stored feature values corresponding to selected validation and provides output signals using a signal delivery main module controlled by static and dynamic classification. The virtual discriminator bank calculates a user adapted allocation based on a face feature of the user and provides a periphery allocation for at least one command modus, and for calculating execution signals for said manipulators.
