Microsoft Proposes Thumb-Driven Interfaces
bonch writes "Microsoft Research has demonstrated examples of two thumb-driven interfaces for handhelds proposed a few weeks ago. Today's devices require the use of two hands; Microsoft wants to reduce this to one. Usability tests showed, however, that some users had difficulty adjusting to the thumb movements. Full researcher's report here."
Not having RTFA I don't know how MS wants people to use this, but if it's for all input, it won't be good.
I used to use a trackball, and I ruined my righthand thumb. I can just operate my cellphone, but even though I haven't used it today, I still have a slight pain in my thumb.
This is my sig. There are many like it but this one is mine. My sig is my best friend. It is my life.
