Most aides carry devices like an iPad and some students also have smart phones. The SAITO software has to sort out what a device does and who it belongs to. Class starts with a formal bow and salute, followed by five minutes of sitting meditation and then five minutes of standing meditation. Then several minutes of centuries-old Chen family warm-up exercises, so we had thought we had a comfortable amount of time until the first Tai Chi Chuan set to perform this identification process. Until Professor Peter Wayne and others at Harvard Medical School pointed out it was useful to measure movements during sitting and standing. We’ll see what the upcoming Internet of Things Conference and the Sensors Expo (both in San Jose California in May and June, respectively) showcase in terms of hardware, but we are leaning toward pressure sensors embedded in chair seats and personal foot mats.
The shortest and simplest (and, therefore, the first taught) of the Chen Family style sets is known by the precise but not especially imaginative name of 18 Movements. Once they learn this set, students would perform it twice per class forever. The students can see a canonical video of Grandmaster Chen Zhenglei, who choreographed 18 Movements, either projected on large mirrors or on smart glasses. 16 students times 20 sensors ties several times per second gets to be a lot of measurements to store in a database very quickly. Well over 100,000 sustained database inserts per minute. And we have to extract the raw sensor data from the Internet of Things hub where it is stored.
