20. ubiquitous computing and augmented realities

EXERCISE 20.1

Many researchers are beginning to explore the potential of ubiquitous computing technologies and applications in the home environment. Discuss how the application themes of context-awareness, automated capture and the continuous interaction of everyday computing is relevant to domestic life. Focus your answer on the challenges of family life or life for an aging population.

The home is a very rich domain for exploring ubicomp. Let's look at one example need in a typical home, finding lost objects. We all have occasions in which we cannot locate some important item in the home. How might ubicomp support this problem? As an automated capture problem, you could imagine being able to retraces one's steps in a home back to a time when you last remember having the lost objects. Accessing a recording of your activities at that time might lead you to remember where you placed the item. Of course, nobody will want to retrace their steps in real time, so it becomes a challenge to think how you might efficiently replay the past. Contextual cues are also very important in trying to track down an item. You may recall when and where you last saw an item, and those contextual cues can be used to index into a captured recording of activity. Contextual cues can also help you to flip through recorded memories, so you might be able to enjoy the last time your parents visited your home, or a precious memory the evening before when a young child performed some skill for the first time. From the perspective of continuous interaction, support for interruption seems very important in a household with lots of children and many activities going on at once. How might you provide an aid to remember where a husband and wife left off in a conversation before being interrupted by children?
