A cognitive architecture for assistive technology in healthcare

This paper proposes an approach of reverse engineering of the human brain. A simplified top level schematic of biological human brain guided by eight aspects namely five sensory input, parallel processor, multi-localized memories, concurrent-heterogonous reasoning, meta-reasoning and interactive behavior is presented. On the basis of this schematic, a theoretical top level cognitive architecture guided by six principles namely multi input, multi memories, parallel signal processing, concurrent-heterogeneous reasoning, meta reasoning and interactive has been developed. This architecture may be a reference for many real time applications in the healthcare industry. The architecture is implemented as a prototype of the intelligent wheelchair with 8051 microcontroller based embedded system. Some advantage of the intelligent wheelchair is discussed to determine the performance of the proposed architecture.
