A family member had a stroke a few years back and now has expressive aphasia. She understands what is said to her, is cognitive of what is going on, but cannot express herself. She is able to respond to yes/no questions (do you want to go shopping? are you looking for your earrings?) She is not, however, able to read (English is not her ...
I am trying to develop a touchscreen keyboard control in a C# WPF project that will be visible when a TextBox gets focus and is hidden when the TextBox loses focus. The projects I have seen for touchscreen keyboards have accomplished this by defining the keyboard as a new window rather than a control. For my application, I would really...
Does anyone know if there's a very big demand for a touchscreen-based keyboard less UI for Car, Navigation, or Mobile devices? I know that Android is a very big, very popular platform. So is Cocoa Touch. What I'd like to envision is using a Java UI with something like Qt that can be applied to a touchscreen. I would initially use And...
Hi, I'm working on a painting application for Android and I'd like to use raw data from the device's touch screen to adjust the user's paint brush as they draw. I've seen other apps for Android (iSteam, for example) where the size of the brush is based on the size of your fingerprint on the screen. As far as painting apps go, that would...
This would ideally be done in C# and is intended for larger form factors (NOT mobiles.). I'm a novice in this area, but would users suggest Silverlight (Can it process touch screens?) or WPF or are other technologies better? Ideally this would involve users tracing shapes with their fingers or a stylus, and the system automatically ma...

I have added a TSHARC touchscreen driver to my Windows CE project, but the touch does not work. The dll is there, as is the touchscreen calibration executable. I have no visibility into which drivers are loaded and when. Any guidance would be appreciated. ...
I'm developing a kiosk-style touchscreen application in Qt. Currently I'm using an Elo Touch surface acoustic wave touchmonitor which works well except for one thing: drag performance is way too poor to provide a good user experience. As this is the case for the cursor in X as well as in my application, it seems to be either the fault of...
I have a subclassed QDialog containing a bunch of subclassed QSpinBox's. When clicking a spinbox, a keypad (another QDialog) where you can use pushbuttons to enter digits. Both QDialog's are activated by calling QDialog::exec(); However, when opening this 2nd QDialog, the first one closes down. I've stepped through it and noticed the 1s...
I'm implementing the scrolling behaviour of a touch screen UI but I'm too tired in the moment to wrap my mind around some supposedly trivial piece of math: y (distance/velocity) |******** | ****** | **** | *** | *** | ** | ** | ...
I'm developing a touchscreen application that, aside from everything else, records the amount of times the screen is used so that the user can be reminded to clean the screen after a predefined number of clicks. I've got the click functions written nicely, all I need now is make sure the function is called on a click. I imagine $('*')....
Hello, I'm writing a MIDlet using the Kuix UI toolkit, and I want to make changes to the toolkit depending on whether the current device is a touch screen device. (These changes include making buttons bigger, for easier tapping.) Is there a way to detect whether the device has a touch screen using J2ME (MIDP 2)? [edit] as a (crappy) w...
I'm trying to create a .NET touchscreen application. I would like to be able to create a large dropdown. By increasing the font size, the button stays the same width but increases in height, meaning it's long and thin. Is there a way to 'scale up' .NET controls so they are large in size for touchscreen applications? ...
Hey everyone, I have a UISegmentedControl in my app (see code below) : // --------------- SETTING NAVIGATION BAR RIGHT BUTTONS NSArray *segControlItems = [NSArray arrayWithObjects:[UIImage imageNamed:@"up.png"],[UIImage imageNamed:@"down.png"], nil]; segControl = [[UISegmentedControl alloc] initWithItems:segControlItems]; segControl.s...

User should be able to touch/grab the item and drag it up or down to scroll the listbox. ...
I'm trying to add some iPhone style scrolling inertia to a web page that will only be viewed on the iPad. I have the scrolling working in one direction (scrollLeft), but it doesn't work in the other direction. It's a pretty simple function function onTouchEnd(event){ event.preventDefault(); inertia = (o...
I have an iPad application that uses the whole screen (that is, UIStatusBarHidden is set true in the Info.plist file). The main window's and main view's frames are set to (0, 0, 768, 1024). The main view has multitouch enabled. The view controller has this code to handle touches: - (void)touchesMoved:(NSSet *)touches withEvent:(UIEve...
Is it possible to simulate the actions of a mouse from a program in OS X? Specifically, the short version is that I'm trying to simulate a touchscreen using two webcams. So assuming I can get X,Y positions, can I send information to the OS as a mouse movement or click? Edit- Or if it's particularly easy in another operating system I'd b...
Hi, i don't really know if it is actually possible, but i believe that it can be made. How possible is it to make a program that recognizes different sound bouncing from the screen and turn it into a position that will obviously be later fed to the mouse. I know that it sounds kind of dumb, but lately i've been noticing that a very dul...
