A position sensitive device and/or position sensitive detector (PSD) is an optical position sensor (OPS) that can measure a position of a light spot in one or two-dimensions on a sensor surface. Principles
Speech generating device using a visual scene display, accessed using a head mouse. Visual scene displays are a different method of organizing and presenting symbols. These are depictions of events, people, objects, and related actions in a picture, photograph, or virtual environment representing a situation, place, or specific experience.
The use of synthesized speech has increased due to the creation of software that takes advantage of the user's existing computers and smartphones. AAC apps like Spoken or Avaz are available on Android and iOS, providing a way to use a speech-generating device without having to visit a doctor's office or learn to use specialized machinery. In ...
The original Speak & Spell was the first of a three-part talking educational toy series that also included Speak & Read and Speak & Math.This series was a subset of TI's Learning Center product group and the Speak & Spell was released simultaneously with the Spelling B (a non-speech product designed to help children learn to spell), and the First Watch (designed to teach children to read ...

[24] The device is then connected to a computer with special software that processes the recording into data metrics including the child's exposure to verbal stimulation, the number of child utterances, and other ...
Electronic fluency devices can be divided into two basic categories: Computerized feedback devices provide feedback on the physiological control of respiration and phonation, including loudness, vocal intensity and breathing patterns. [1] Altered auditory feedback (AAF) devices alter the speech signal so that speakers hear their voices differently.
A silent speech interface is a device that allows speech communication without using the sound made when people vocalize their speech sounds. It works by the computer identifying the phonemes that an individual pronounces from nonauditory sources of information about their speech movements .
The AlterEgo was designed by Arnav Kapur, a graduate student at MIT, [4] and became public in 2018. The device was designed to help people with speech disabilities. [5] In 2018, the device was presented at the Conference on Intelligent User Interfaces where the research team reported a 92% median word accuracy rate.
