An optical mouse is a computer mouse which uses a light source, typically a light-emitting diode (LED), and a light detector, such as an array of photodiodes, to detect movement relative to a surface. Variations of the optical mouse have largely replaced the older mechanical mouse design, which uses moving parts to sense motion.
The SENS Research Foundation is a non-profit organization co-founded by Michael Kope, Aubrey de Grey, Jeff Hall, Sarah Marr and Kevin Perrott, which is based in California, United States. Its activities include SENS-based research programs and public relations work for the acceptance of and interest in related research. [citation needed]
After a short introduction and training, respondents can follow their attention with the mouse. In comparative studies with classical machine-based procedures significant correlations (r>0.92) were found between the data gained with the machine-based procedure and the data gained with AttentionTracking.
Mouse tracking (also known as cursor tracking) is the use of software to collect users' mouse cursor positions on the computer. [1] This goal is to automatically gather richer information about what people are doing, typically to improve the design of an interface.
A rotational mouse is a type of computer mouse which attempts to expand traditional mouse functionality. [1] The objective of rotational mice is to facilitate three degrees of freedom ( 3DOF ) for human-computer interaction by adding a third dimensional input, yaw (or Rz), to the existing x and y dimensional inputs.
Compressed sensing (also known as compressive sensing, compressive sampling, or sparse sampling) is a signal processing technique for efficiently acquiring and reconstructing a signal, by finding solutions to underdetermined linear systems.
