Last year, New York University professor Jeff Han launched a company called Perceptive Pixel, which builds six-figure plus custom multitouch drafting tables and enormous interactive wall displays for large corporations and military situation rooms. A camera below the surface captures the diffusion and sends the information to image-processing software, which can read multiple touches simultaneously and translate them into a command.
The system sends information about screen touches to applications via the lightweight Open Sound Control protocol, utilized for network-based communication between computers and multimedia devices, and User Datagram Protocol data transport technology.
The applications then take the appropriate actions. They could be used for collaborative work on design-related and other projects, perhaps in place of interactive whiteboards, he said. Short-term success for a technology can be measured by how much attention a product gathers when it is new.
Long-term success is measured by how effectively that product disappears into the everyday routine of life. Figure 6 5. Water Water is used as an "attract mode" for the Surface desktop, and it is certainly attractive. The default background picture is an image of smooth pebbles that appear to sit beneath a thin layer of rippling water.
By itself, the water moves as if it were being disturbed by a light breeze, but it is when you touch the screen that it becomes more interesting than just another screensaver. Figure 7 Tapping anywhere on the surface causes larger ripples to spread out from the point of contact.
Many people can tap at the same time, making an effect similar to a rainstorm.
But by far the most fun is when you sweep your whole hand across and cause waves to bounce back and forth. The physics of the water simulation is not perfect: the ripples never get above a certain intensity, and there is no way to simulate diffraction.

However, cameras are subject to occlusion by other objects that may result in a loss of gesture tracking. Infrared cameras are most common in three-dimensional implementations. Interaction methods[ edit ] Various methods of interaction exist in surface computing.
The most common method of which is touch based, this includes single and multi-touch interactions. Other interactions exist such as freehand 3D interactions that depth-aware cameras can sense. Depending on the system, multi-touch gestures, such as pinch to zoom , are supported.
These gestures allow the user to manipulate what they see on the surface by physically touching it and moving their fingers across the surface.
For sufficiently large surfaces, multi-touch gestures can extend to both hands, and even multiple sets of hands in multi-user applications. Such gestures allow the user to move in three dimensions of space without having to come into contact with the surface itself, such as the methods used in DepthTouch.
Instead of physically touching the screen, the user can manipulate the objects he or she sees displayed onto it by making freehand gestures in mid-air. The depth-aware camera can then detect the user's gestures and the computer processes them to show what the user is doing on the display. Applications[ edit ] Surface computing is used in both research and commercial use.
It is more widely known commercially in products such as the iPad.
Although tablets like the iPad are among the most common types of surface computing other implementations exist, such as HP's Sprout computer. In research, surface computing has been used to help develop gestures for tabletop implementations.
Alternatively, an augmented reality headset may be used to display images on real-world objects. Displays can be divided into single-viewpoint and multi-viewpoint displays.
Single-viewpoints include any flat screen or surface where viewing is typically done from one angle. A multi-viewpoint display would include any three-dimensional object surface like a sphere or cylinder that allows viewing from any angle.
Front and rear projection techniques are also utilized. The advantage of a projector is that it can project onto any arbitrary surface. However, a user will end up casting shadows onto the display itself, making it harder to identify high detail.
Infrared cameras[ edit ] Infrared or thermographic cameras are used to facilitate gestural detection.
Unlike digital cameras, infrared cameras operate independently of light, instead relying on the heat signature of an object. This is beneficial because it allows for gesture detection in all lighting conditions.
However, cameras are subject to occlusion by other objects that may result in a loss of gesture tracking. Infrared cameras are most common in three-dimensional implementations.
Interaction methods[ edit ] Various methods of interaction exist in surface computing. The most common method of which is touch based, this includes single and multi-touch interactions. Other interactions exist such as freehand 3D interactions that depth-aware cameras can sense.Unlike the screen resolution, which for the time being is constant, the touch resolution varies according to the size of the screen usedit is designed to work at a resolution of 48 dots per inch.
After extensive testing and user research, the final hardware design seen today was finalized in Such gestures allow the user to move in three dimensions of space without having to come into contact with the surface itself, such as the methods used in DepthTouch. Although there were related efforts happening in academia, Bathiche and Wilson saw the need for a product where the interaction was richer and more intuitive, and at the same time practical for everyone to use. Well, in a way that is true.
With multi touch devices, one or more users activate advanced functions by touching 13 Dept of IT Surface Computing a screen in more than one place at the same time. Then, with the flick of your finger, you order dessert and split the bill. The various demonstration programs are accessed from a main menu, which scrolls left and right in an endless loop.
