Claim 0:
1. Electronic equipment having a display, the electronic equipment comprising:
an ultrasound emitter adapted to emit a first ultrasound signal into at least a space that the display faces, and repeat the emission at an interval that depends on a preset distance within which the electronic equipment supports floating touch, wherein the greater the preset distance, the greater the interval is;
an ultrasound receiver adapted to receive a second ultrasound signal that is an echo of the first ultrasound signal reflected by an object;
a processor that is coupled to the ultrasound emitter and the ultrasound receiver, the processor being adapted to acquire a floating touch signal by locating the object in three-dimensional space according to charactering information charactering the first ultrasound signal and the second ultrasound signal, and execute an instruction corresponding to the floating touch signal; and
a temperature detector adapted to detect an ambient temperature of the electronic equipment,
wherein the processor is adapted to activate floating touch to control the ultrasound emitter to emit the first ultrasound signal in response to the ambient temperature being within a preset temperature range.
