Abstract
The following quote was obtained by the news editors from the background informa tion supplied by the inventors: “Much of human activity involves the use of hand s, often in conjunction with objects. However, activities such as pill-taking an d remembering to take one’s keys when leaving home are quite complex to model. F or example, such activities involve finer micro-activities which can be performe d in varying sequences. In addition, distractions and disturbances can arise whe n performing these activities so there are significant variations from individua l to individual and even for an individual from one time to next.
