![]() ![]() Desktop operating systems, such as Mac OS X, Windows 7 and Ubuntu, as well as mobile operating systems, including iOS, Android and Symbian^3, already support multitouch detection. To meet the demand for multitouch device capability, more operating systems provide integrated interface support. Some laptop trackpads, such as the MacBook Pro version, also support multitouch gestures. Tablet PCs like the Apple iPad, and touchables like the Microsoft Surface are examples of such devices. Multitouch technology is mostly used in smartphones, but larger devices also support such interfaces. Using multitouch screens, a user may achieve the same effect with clockwise or counter-clockwise finger gestures. Similarly, in the past, object rotation required a user to press a virtual button, usually symbolized by a two-triangle icon. With multitouch, a user achieves the same effect with specific finger gestures. Prior to the introduction of multitouch technology, a user would press a real or virtual button to zoom into a document or image. Today’s most popular smartphones and tablets have multiple touch detection capability. The earliest touchscreens were built with single touch detection. Multitouch also enables wiping and rotating, which offers enhanced user and virtual object interaction. Theoretically that's in the right direction though.Multitouch functionality enables users to perform multiple finger gestures, such as pinching the screen for zooming in, or spreading the screen for zooming out. Technically that might work, but I'd like it to be a smooth continuous surface and also doing that would mean many thousands of dollars spent on additional features in the phones which I don't need. I like your thinking though, I remember being impressed with it when I first experienced it.Ī few bezel-less phones (or tablets, if they exist) placed side to side should do the job to create such a screen. Multi-touch might be impossible with that technology however.Īn art class I took had one of these that I got to use, that's the right direction but I really need multitouch, and also the response time on it was a bit slow for my purposes. "electronic whiteboard" may also get you closer to what you want. Kind of, if I can get one big enough and supporting multitouch (and preferably one that doesn't cost an arm and a leg) Would something like a digitizer tablet work? I just need a version that's about 10 times bigger lol This was true a few years ago, but my Galaxy S9+ has no problem selecting between desired characters (small ones at that) first try. Usually can't even get the correct line, let alone the correct start or end character. Try selecting text in a text message, to edit it, and see just how "high resolution" the sensing is. Thought of doing something like this, is multitouch possible with that? If so then it might be perfect but I'm not sure how that would happen ![]() Some only detect 5 spots and calculate from capacitive differences. The output is ASCII through a COM port so the interface to an Arduino should be no problem. The tablet is not touch sensitive you have to press a button to output a point or you can set it to output a stream of coordinates as you move the cursor across the face of the tablet. Would something like a digitizer tablet work? I used to sell and install these tablets which were used to digitize maps into CAD systems. The main thing right now is: how do I get a giant, precise, multitouch surface that can interface with Arduino (or a Teensy or Pi if I need more power) without spending a fortune? And at Microhire, we have the technology to do just that. The UI will be a physical graphic painted or etched onto the surface (hence I don't need a lit display), and it'd be nice if there was the ability for the whole surface to be transparent but I won't get ahead of myself if that ends up being difficult. What makes a memorable event Turning guests into participants. I need a BIG surface (about 4" wide and about 40" long) with preferably millimeter or sub-millimeter precision, and multitouch capability. I say "touch-surface" rather than touchscreen because I don't necessarily need an actual screen or display, just a surface that can sense precisely where it's being touched. ![]()
