Apple working on adding multi-touch to iPod click-wheels
Having pioneered multi-touch for its iPhone and iPod touch handhelds, Apple later extended the technology to trackpads on its Mac notebook line and now appears ripe to introduce the first iPod click-wheels with similar capabilities.
Though sales of the iPod touch have taken off in recent quarters, recent reports suggest that we haven't seen the last of click-wheel-based iPods, the next of which is expected to turn up this fall in the form of a fifth-generation iPod nano with a built-in digital camera and more compact circular scroll wheel.
This new nano could be the first iPod support multi-touch gestures through its click-wheel, according to recent patent filing discovered by AppleInsider this week that details methods for detecting "input gestures that traverse the center of the scroll wheel and to detect multi-touch input."
