Abstract

This paper examines the context of mobile computing within facilities maintenance activities on the basis of an analysis of cursor movement and point and click disruptions that may occur when a number of perturbations are induced by the computing environment. An analysis based on context-aware computing distinguishes between situational induced impairments and disabilities (SIID) whose properties are related to Health Induced Impairments and Disabilities (HIID) such as motion impairment, tremor or spasm. A number of technology solutions based on Assistive Technology interventions for motion impaired cursor movement stabilization are possible approaches to counter SIID in Mobile computing for maintenance environments. A software based cursor movement smoothing method based on statistical state space filtering is presented as an example of a new development of one such approach.
