Needs People are unable to reach their desired level of fitness due to the inaccessibility of personal training or other problems associated with the human element of personal training. These problems include a lack of knowledge which makes it difficult to correctly perform an exercise and raises the risk of personal injury. Motivation can be difficult to maintain when an individual attempts to exercise or train alone, but personal trainers are often prohibitively expensive, and the quality and availability of personal trainers varies, forcing the trainee to accommodate the trainer. There is a need for an inexpensive, portable system that educates users on how to perform exercises safely while maintaining their motivation.

Specifications Marketing Requirements Engineering Requirements Justification 1 A. The user will be shown diagrams, animations, The user needs to be presented with enough or videos which demonstrate the proper information to be able to perform the exercise techniques for exercises. correctly. Users should be able to learn from the demonstration well enough that the system will not frequently correct him or her; using the system should be a positive experience. 1 B. The user will be warned if the sensors detect The system should gently correct the user's that the user's motions significantly mismatch motion and guide the user to proper technique. proper technique (i.e., > 10 deviation from expected motion.) 4, 5 C. Each set of sensors will be able to run for the There is a zone associated with physical activity duration of a regular workout without being (e.g., runner's high).

If the user rolls on his or her side (and thus onto the device strapped to his or her arm), the device should withstand this motion. 3 H.
