edge swipe detection on optical multi-touch monitors and all in one pcs RRS feed

  • Question

  • I am using a Dell ST2220T multi-touch monitor. I am finding it very difficult to get reliable swipes from the edge due to the bezel that is present on all optical based touch screens. Using a plastic stylus, it works fine, but does not always work well with finger.

    In the Build conference videos they mention needing to detect the inward swipe over pixel 1.

    Is there a way adjust the sensitivity of this? Perhaps there could be a setting that says to use 5 pixels instead of 1 for instance.

    I believe this will be a real problem for all those all in one touch PCs out there -- which otherwise will make great Win 8 machines. I think capacitance touch screen on a 20+ inch monitor is way too expensive so optical touch will be here for a while.

    I'm using an HP Touchsmart 600 and am experiencing the same problem. It will occur on any screen presenting a bezel. Being able to access to 1px borders around the screen seems to be a very tough constraint (for example cases or sleeves on some tablets could avoid this access, not to mention existing screen designs), especially when your screen is High Dpi...

    Would love some sort of workaround.
