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."
While your other hand holds the device... this is for small devices you hold, think phone/pda, not a laptop you sit on a desk (or toast your balls with).
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.
