So you want to have another way to interact with your smartphone? ForcePhone can help. It is a software that can be installed on any smartphone, allowing users to command their phone with force and pressure. The phone’s body registers the force by using the microphone and speaker.
Here is how the technology works, according to University of Michigan computer engineers:
The software sets the speaker to emit an inaudible tone at a frequency higher than 18 kHz, which is outside the range of human hearing. But the phone’s mic can still pick up the vibration caused by the sound. When a user presses on the screen or squeezes the phone’s body, that force changes the tone. The phone’s microphone can detect that, and the software translates any tone tweaks into commands.
ForcePhone simply lets you interact with your phone with force and pressure. What do you think? How can researchers take this idea to the next level?
