This Design Idea utilizes an optical computer mouse's sensor for measuring rotation of a disk which can be mechanically connected to any sort of rotating apparatus. One feature is to allow adjustment ...

Readers with long memories will remember the days when mice and other similar pointing devices relied upon a hard rubber ball in contact with your desk or other surface, that transmitted any motion to ...

Wanting to experiment with using optical mouse sensors but a bit frustrated with the lack of options, [Tom Wiggins] rolled his own breakout board for the ADNS 3050 optical mouse sensor and in the ...

The sensor of some optical mice can be used to easily and cheaply detect counterfeit euros, according to a study published by researchers of the University of Lleida (UdL) in the scientific journal ...

Finding a mouse that achieves the perfect balance between sensitivity and accuracy might seem next to impossible. Laser-based mice offer high sensitivity, but they tend to cause jittering. On the flip ...

TL;DR: Researchers from the University of California developed Mic-E-Mouse, an AI-powered tool that exploits high-DPI optical sensors in gaming mice to eavesdrop on speech by detecting surface ...

It would be difficult to go through the day without seeing evidence that the touch interface has become the most popular way of interacting with smartphones. Indeed, Apple’s introduction of the iPhone ...

Taiwan-based IC design house PixArt Imaging (PXI) signed a cross-licensing agreement for optical image sensor intellectual properties (IPs) with Avago Technologies, an IC design house spin-off from ...

Past a few essential features and reasonably accurate tracking and latency, gaming mice are a mostly personal choice. The specs, like “DPI” and “IPS” have been cranked so high lately that it’s ...
