It is possible. You won't get any dual-touch that way, though, unless you come up with your own way of doing that.

The HP TouchSmart shell is just that: a full-screen app that responds to clicks, drags, etc.

OK - but I tested one of these out at the store, with a Full screen flash app.

In Full-screen mode, the program refused to respond in any way. When not in fullscreen (displayed in a window), the buttons would only register the Release and drag events on the screen.

In other words, if I create buttons that respond to both a mouse press and a mouse release separately (for intuitive feedback), is there a way I can make the Mouse Press work with the touchscreen? As I said, in my tests it seemed to only register that you were dragging your finger on the screen, but not that you simply pressed and held down (except for the circle which appears around the cursor - something that would have to be disabled if possible).

Thanks

I'll have to look into that a bit. It is true that there are no "mouse move" events unless you have your finger on the screen, since the technology has no proximity sensing. Tablet PCs usually have that. The circle that appears is what simulates a right click.

Thanks for the response.

If you could let me know what you're able to find out that would help.
- Specifically, I need to make sure my Flash or Air apps will play fullscreen (I think something in the TouchSmart UI may have been interfering?)
- I need to be able to make each of my buttons have feedback as soon as they're touched, as well as on the release from the screen
- Need to be able to disable the 'right-click circle'

The TouchSmart will work as a great alternative if it can be configured to behave as a commercial TouchScreen would.

Thanks for your help!

Anyone find any answers to theses questions? I find myself in the same boat.

I am also very interested in this. @GeekTieGuy have you found anything out?

Sorry, I think I was overly optimistic with what I thought I could accomplish at the time. I don't have too much experience with Flash, and right now other things are taking priority as far as what I can spend my time on.

My guess is that the hardware only turns stationary touch events into mouse events upon lifting the finger. That's why there are no mouse down events when you put a finger down. Perhaps there are some documents available from NextWindow, the providers of the touch screen technology that go into details around this.

Disabling right-click circle: Control Panel > Hardware and Sound > Pen and Input Devices > Touch tab > select Press and Hold in the list and click Settings button > uncheck Enable press and hold for right clicking > Ok > Ok

You can find information about touch events into mouse events here http://msdn.microsoft.com/en-us/library/cc872774.aspx (scroll down to Touch interactions | System gestures. Hover is not supported). A quick single touch down to a button generates a mouse click event.

I'm finding "touch screen, finger down" is not the same as "mouse down".

I'm working on a touch UI using a TouchSmart tm2 notebook/tablet running Win7 x64, Core i2 and LabView (x64) 2010. When the screen is touched, the "switch when pressed" (momentary, normally open) controls in LabView are not acknowledged. When hit with a "mouse down" they work fine.

All other programmable LabView controls work great with the touch screen until I start to tax the processor then the touch screen "finger down" starts to become intermittent. Again "mouse down" works fine.

National Instruments has a Touch Panel Took Kit that may address this problem for and additional $800. I plan to look into this in the future.

I did spend some time changing settings in the tablet, finger and pen controls in the Windows control panel, nothing seemed to make a difference and nothing was jumping out at me.

Right now this "touch screen finger down" problem is not a show stopper but I would like to find a simple work around.

The touch UI I just finished is pretty impressive, responsive and works well.

I have been exploring the boundaries of the touch capabilities of the tm2 and LabView for the last week and a half. I wanted to post my findings before I have to hand off on this project.

This thread has been dead for quite a while so I'm thinking there is no simple/cost effective answer.

Your comments please.

Did anyone on this thread ever have any luck with disabling the touchsmart button on the lower right corner of the machine? We're outfitting a TouchSmart 600 for a museum kiosk and were informed the button would be easily accessible by the general public (yikes!).

Any help will be greatly appreciated!
