Actigraphy is a non-invasive method of monitoring human rest/activity cycles.
determining sleep patterns and circadian rhythms
Actigraphs have a number of different ways of accumulating the values from the accelerometer in memory. ZCM (zero crossing mode) counts the number of times the accelerometer waveform crosses 0 for each time period. PIM (proportional integral mode) measures the area under the curve, and adds that size for each time period
TAT (time above threshold) uses a certain threshold, and measures the length of time that the wave is above a certain threshold. Literature shows that PIM provides most accurate measurements for both sleep and activity, though the difference with ZCM is marginal.
Fastest sample rate: 1-minute intervals provide adequate detail to measure sleep,
Weight: the heavier the actigraph, the more disruptive its use.
making our system more game-like will make it more fun and motivating”
1) determine business objectives;
2) translate objectives into desired customer behavior;
3) assign points to desired behaviors;
4) assign (primarily extrinsic) rewards to points;
5) polish it off with some virtual trophies, a leaderboard and social media integration.
Gamifying a commercial system requires knowledge of not only the existing system but also the principles of game design.
