Visual Screen: Transforming an Ordinary Screen into a Touch Screen
Touch screens are very convenient because one can directly point to where it is interesting. This paper presents an inexpensive technique to transform an ordinary screen into a touch screen using an ordinary camera. The setup is easy: position a camera so it can see the whole screen. The system calibration involves the detection of the screen region in the image. which determines the projective...
متن کاملFicon: a Touch-capable Tangible 3D Display using Optical Fiber
Copyright is held by the author/owner(s). ITS’12, November 11-14, 2012, Cambridge, Massachusetts, USA. Abstract We present a touch-capable 3D displaying device for tabletop systems called a Ficon. A Ficon has a 2.5-dimensional shape for providing tangible dynamic 3D visual. While most tangible devices for tabletops display their associating information around themselves, a Ficon displays such i...
متن کاملTransparent Film Technology for Touch Screen and Flexible Display Applications
Flexible electronic displays and touch screens are increasingly used in demanding outdoor environments. Design engineers are challenged to develop optical systems that meet a wide thermal range (-55° to + 85° C) and comply with diverse optical, electrical and mechanical parameters. This paper discusses the optical and mechanical properties of substrates and thin and thick film coatings used in ...
متن کاملTouch a Screen or Turn a Knob: Choosing the Best Device for the Job
Input devices enable users to interact with systems. In two experiments, we assessed whether and how task demands and user age influenced task performance for a direct input device (touch screen) and an indirect input device (rotary encoder). In Experiment 1, 40 younger (18-28 years) and 40 middle-aged to older adults (51-65 years) performed tasks using controls such as sliders, up/down buttons...
متن کاملOptical Touch Screen based on Grating and Waveguide
An optical touch screen based on gratings and waveguides is proposed. Light from the backlight source with the wavelength of 440nm is coupled into the waveguide matrix by gratings for sensing. Small detector arrays are included. The design significantly reduces the cost and complexity as compared to conventional optical touch technologies, which can also improve the color purity of the display....
