These pointing and navigation disk devices are built to enhance handheld devices. They use an electrically-variable resistive rubber sensor, along with simple plastic components mechanical design geometries and a sophisticated firmware algorithm. These parts all work together to translate user motion on the actuators in two different dimensions on a circular sensing element. They come in 360-degree or N-way full-variable speed analog control. The electrical interface is received through five standard GPIOs and emitted through an 8-bit analog-to-digital converter. It needs 8-bit support or extra processors when employing I2C, PS2, UART or SPE interfaces. It's designed to last through more than 3 million life cycles. It comes in standard reference design (straight drop in), module design (reference design with customized actuator and without PCB), or fully custom solutions.
Major global metropolitan areas are implementing a vast number of technology, energy, transportation, and Internet projects to make the metropolis a friendlier, greener, safer, and more sustainable place to be.
