Challenges in design & deployment of assistive technology

Today's scientific era has contributed immensely to the design and deployment of interfaces to aid physically handicapped people to combat their disabilities. The alternate interfaces assist individuals in leading a normal life and perform expected activities. Such types of interfaces are the part of Assistive Technology. There are different phases between design and deployment of assistive technology i.e., initial level of design, deep design, model design and modeling. The designer faces a lot of problems in designing the assistive technology due to various disability levels, user adaptability, user acquaintance etc. The deployment team is totally dependent on the designed interfaces and is totally ignorant about the usability of the devices. So through this paper we highlight some of the challenges encountered in the design and deployment of assistive devices and suggest certain principles to control them. Affective design and deployment leads to increased acceptability levels of assistive devices in society.
