Analogies for Assistive Technology Requirements
Medical situations or probabilities that require prompt response and might otherwise confine the individual to a strictly monitored environment
Desire for maximal independence of mobility and location
Need for local prompt alert and response while maintaining strong connection to a distant management site
Great technical solutions for sensing, data management and telecommunications awaiting application
