The days of cumbersome texting and inaccurate controls that accidentally activate more buttons than you intended to press could be over.
Quantum Research Group has developed a circuit that allows more accurate results when using keypads.
The QT1101-Q Touch charge-transfer is a digital controller that operates when touched and can also sense fingers that don't make actual contact.
Each of the ten possible channels operates independently and the new adjacent key suppression (AKS) technology ensures that only the nearest key is activated when a user's finger hovers over several keys.
The new chip is also power efficient as it can be switched to a low power mode.
This development will be useful to consumers as it will find its way into numerous electronic appliances, mobiles and gaming devices.
