Whilst standing beside the patient place your index finger on one of the lumbar vertebral spinous processes, and your middle finger on the next one down and ask the patient to bend over and touch their toes, keeping their legs straight. Normally, as the patient bends, the spinous processes will move apart, so your fingers will move apart also.
Two-point discrimination (2PD) is the ability to discern that two nearby objects touching the skin are truly two distinct points, not one.It is often tested with two sharp points during a neurological examination [1]: 632 [2]: 71 and is assumed to reflect how finely innervated an area of skin is.
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.
Furthermore, some gloves can detect finger bending with a high degree of accuracy (5-10 degrees), or even provide haptic feedback to the user, which is a simulation of the sense of touch. The first commercially available hand-tracking glove-type device was the DataGlove, [ 17 ] a glove-type device that could detect hand position, movement and ...
Users interact with the device by physically pressing items shown on the screen, either with their fingers or some helping tool. Several technologies can be used to detect touch. Resistive and capacitive touchscreens have conductive materials embedded in the glass and detect the position of the touch by measuring changes in electric current.
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 ...
Finger tracking of two pianists' fingers playing the same piece (slow motion, no sound) [1]. In the field of gesture recognition and image processing, finger tracking is a high-resolution technique developed in 1969 that is employed to know the consecutive position of the fingers of the user and hence represent objects in 3D.
Full body scanner in millimeter wave scanners technique at Cologne Bonn Airport Image from an active millimeter wave body scanner. A full-body scanner is a device that detects objects on or inside a person's body for security screening purposes, without physically removing clothes or making physical contact.
