Abstract
The sensing capabilities in mobile and IoT devices form fundamental building blocks for applications. The broader the spectrum of our sensing capabilities, the more applications we can facilitate.
However, there is a tangible limitation imposed by the perceived power the device can provide. With over 5 million apps in circulation across Android and iOS devices, it may seem that most applications merely recycle these same building blocks and offer similar functionalities.
The question then arises - can we expand our perception with fewer sensors? In this talk, I will demonstrate that, with the use of commercially available speakers and microphones, we can not only sense environments but also manipulate other sensors. This, in turn, boosts the capabilities of mobile devices without necessitating the addition of any extra hardware. The aim is to explore and exploit untapped potential, transcending conventional limits and enabling a new era of sensor utilization and application innovation.
