Touch screens and gesture-based technology
Touch screens and gesture-based technology interpret human gestures and turn them into control methods for digital interfaces, translating movements such as swipe to turn a page of virtual type. The gesture-based interfaces purely, you do not have to touch the screen at all or where your gestures simply “touching” a virtual or projected screen, point to replace the touch screen technology. Until then, multitouch interfaces that depend on many input gestures serve a transition to pure gesture based control.
1. Understand the difference between interfaces. Resistive touchscreens recognize a single point of contact at a time, while capacitive touchscreens recognize several. Infrared touch screens present in mobile devices such as SGH-E900 and Samsung U600, also have this ability and often based on gestures, touch screen interfaces.
2. Use all devices that use multitouch capacitive or infrared touch screens, in order to recognize as many contact points as possible. Common examples include the iPhone from Apple , the Google Nexus One, Samsung Wave and the Desire of HTC . Although the interface of each device is different, practice with multitouch devices helps you become familiar with conducting gestures to interact with a user interface. For example, use three fingers to drag objects around the screen, pinch the screen to zoom inwards, passing through the touch screen as a book which hojearas turn the pages in the multi system Apple .
3. Get to become hybrid devices based touchscreens and gesture-based control in pure gestures. For example, the Pantech Vega LTE – available only in Korea from February 2012, but plans to be released worldwide, usually uses the multi-touch interaction, but yet its handsfree allows do your hands float on the screen to control your phone, allowing you to answer the phone, by moving your hand across the screen.
4. Stay tuned on prototype devices that basically transform common surfaces in gesture-based touchscreens. For example, the Mogees project uses the piezoelectric effect to convert any surface that has been stuck in a virtual instrument based on contact and gestures, allowing you to touch, swipe and even tapping to produce musical sounds. Thus, the surface becomes the “screen”. The projects TouchLight project an acrylic plastic screen, which allows you to stand in front of it and control the user interface with the movement of your hands. Although these projects are not commercially available, keep up on the latest developments in gesture-based touchscreens and gesture-based pure help you become familiar with these concepts of control before coming to market interfaces. Visit sites like “Engadget and Wired” to read the latest technology news. If possible, attend trade shows as the “Consumer Electronics Show”, the “OCE Discovery” or “MIGS” to obtain practical experience with the latest interfaces.
5. Browse Xbox 360 interface with the Kinect accessory. This device offers perhaps the most accessible form of simple gesture-based controls, intended to replace the standard touch screen as the primary method of user control. Besides voice controls and facial recognition is based on Kinect gestures to control the navigation, such as raising your hand to tell the system your presence or slide your hand to scroll through the menu. Depending on the game, Kinect also means full body gestures such as jumping, kicking and punching action on a screen.
