Fujitsu has announced the release of multi-input resistive touch panels with the ability to detect simultaneous inputs. This means that potentially you could have input coming from your finger and from a stylus at the very same time. While multi-touch is nothing new to most readers (especially those with a taste for Apple products), it should be clarified that this functionality is normally associated with capacitive touch screens and not resistive panels like these new ones from Fujitsu.
Anyone who has tried to use a multi-touch touchscreen with anything other than their bare skin will know that it’s just not possible, no matter how hard you press. That’s because the capacitance technology used for the bulk of multi-touch devices
doesn’t detect pressure, but measures the changes in electrical resistance caused by contact with a conductor – in this case, the human body. That might be annoying in cold climates, but is an even bigger problem in situations that require the wearing of protective gloves. Getac’s line of rugged Tablet PCs
will be the first commercially-available rugged computers to solve this problem by offering a multi-touch screen that works with or without gloves.
