Design outcomes

Primary

Measure	Time frame	Description
physiological parameter: acceleration data from built-in sensor with unit: m/s^2	40 seconds	Using the built-in sensor to record the acceleration data during each seconds trial. Both x, y and z axialis will be recorded
physiological parameter: orientation data from built-in sensor with unit: degree	40 seconds	Using the built-in sensor to record the acceleration data during each seconds trials. Both x, y and z axialis will be recorded
