Trends on touch sensing
- Product feature: digital touch goes capacitive, Jul. 14, 2008.
It is now common for even relatively mundane devices, such as an electric drill or a vacuum cleaner, to use a programmable device for its control algorithms, but the same level of sophistication has yet to migrate to the user interface. Where there could now be a touch panel display and solid state relay, it is still more common to find conventional LEDs and discrete switches.
