摘要:
A wearable device capable of indicating direction is provided, including a wearable module, a plurality of acoustic wave sensors, a plurality of vibrators, and a control module. The wearable module is adapted to be worn on the user's body, the acoustic wave sensors and the vibrators are disposed on the wearable module in different directions. The control module is electrically connected to the acoustic wave sensors and the vibrators. Each acoustic wave sensor is driven by a sound signal generated by an external object to generate a response signal, the control module receives and compares the response signals to recognize the direction of the external object, and controls the vibrator to generate the vibration signal.

A seat cushion includes a cushion body, a weight measuring unit coupled to the cushion body, a tilt adjusting unit, a storage unit storing pre-established mapping data, and a controlling unit. The weight measuring unit measures, when a user is sitting on the cushion body, weight of the user applied to the cushion body so as to generate a result of weight measurement. The controlling unit is connected to the weight measuring unit, the tilt adjusting unit and the storage unit, and controls, when the seat cushion is operated in an automatic mode, the tilt adjusting unit to adjust a seat angle of the cushion body with respect to a horizontal reference plane based on the result of weight measurement, a height value and the mapping data.
