BENGALURU: In the film Dark Knight, When Batman turns all the smartphones in the city of Gotham into a sonar system to track Joker, it caught the attention of millions. The movie and Batman’s techniques of fighting crimes have never failed to amaze its viewers. According to a recent article by India Today, engineers from the University of Michigan have developed a Batman inspired software, ForcePhone which enables users to make a call, merely by squeezing their Smartphone with their palm.

The software gives any smartphone the capacity to sense, force or pressure on its screen. Expensive and advanced sensors installed in smartphones can solve any kinds of problems that the software enables, but the added cost and tedious installation comes along with it. The user interface of ForcePhone has been augmented without the requirement of any built-in sensors, allowing user to do away with the additional cost. To unlock a menu of additional options, users can push the screen button a bit harder, similar to right-clicking with a mouse.

The software, with the help of a smartphone's microphone and speaker can emit ultrasound covering the 18-24 KHz range which is beyond the spectrum of frequencies detectable by the human ear. Although ForcePhone is not yet ready to be rolled out to consumers; a demo of the software will be given at MobiSys 2016 in Singapore.
