Embedded Sensor Penetration on Modern Mobile Devices
I'm currently doing some research related to embedded sensors in mobile devices. In the research, I utilize data collected from the accelerometer, gyroscope, and touchscreen of the device. My motivation behind using these sensors in particular is that they are available almost universally on smartphones and tablet.
However, because this is research, I need to back up the claim that they are available everywhere with numbers or results. I am having a hard time finding a source that shows the percentage of mobile devices with a given sensor. For example, a list like this would be ideal:
Front-Facing Camera: 69.3%
Rear-Facing Camera: 79.5%
Any help from the wizard developers here is much appreciated.
R - How many devices on the market have a certain sensor?
