A touch user interface (TUI) is a computer-pointing technology based upon the sense of touch ().Whereas a graphical user interface (GUI) relies upon the sense of sight, a TUI enables not only the sense of touch to innervate and activate computer-based functions, it also allows the user, particularly those with visual impairments, an added level of interaction based upon tactile or Braille input.
In 1990, Sears et al. published a review of academic research on single and multi-touch touchscreen human–computer interaction of the time, describing single touch gestures such as rotating knobs, swiping the screen to activate a switch (or a U-shaped gesture for a toggle switch), and touchscreen keyboards (including a study that showed that ...
A touchscreen (or touch screen) is a type of display that can detect touch input from a user. It consists of both an input device (a touch panel) and an output device (a visual display). The touch panel is typically layered on the top of the electronic visual display of a device.
FingerWorks was a gesture recognition company based in the United States, known mainly for its TouchStream multi-touch keyboard. Founded by John Elias and Wayne Westerman of the University of Delaware in 1998, it produced a line of multi-touch products including the iGesture Pad and the TouchStream keyboard, which were particularly helpful for people suffering from RSI and other medical ...
The term "gesture recognition" has been used to refer more narrowly to non-text-input handwriting symbols, such as inking on a graphics tablet, multi-touch gestures, and mouse gesture recognition. This is computer interaction through the drawing of symbols with a pointing device cursor.
Earlier this week, the Wall Street Journal reported that raw Arabica coffee prices soared to a record high of nearly $3.44 per pound, which beat the prior record of $3.35 from 1977.. MORE: Climate ...
An important technical reason for the limitation to gesture-enhanced single-touch instead of allowing dual-touch or multi-touch is the type of sensor hardware in the display. Many touchscreen technologies obtain two independent measurements per touch to acquire a 2-dimensional position. Given two distinct touches, however, this returns two ...
US stocks ended Friday in the red, closing out a lackluster week despite a year of historic highs. The Dow was lower by 333 points, or 0.78%, after the closing bell. The S&P 500 lost 1.1% and the ...
