Abstract: A mobile device includes sensors and a processor. The sensors are disposed on opposite edges of the mobile device respectively. The processor is configured to collect a first data set labeled with a right hand holding gesture, collect a second data set labeled with a left hand holding gesture, establish a determination model associated with the first data set and the second data set, and in response to the processor collects a third data set comprising the holding positions and the force values detected by the sensor, determine a current holding gesture according to the third data set in reference to the determination model.

Abstract: The grill oven mainly contains an oven body, an oven cover, a pair of seat pieces, a pair of H-shaped stands, a pair of boards, two pairs of sliding rails, and at least a pair of wheels. The seat pieces are provided along a front bottom edge and a back bottom edge of the oven body. The stands are provided and hinged along a left bottom edge and a right bottom edge of the oven body, so that they could be folded beneath the oven body. The pairs of sliding rails are provided so that the boards could be slid laterally in and out of the left and right sides of the grill oven. On either a left or right end of the seat pieces, the wheels are provided, respectively. The grill oven could be hand carried or pulled on its wheels.
