Vibratese
Vibratese is a method of communication through touch. It was developed by F. A. Geldard, 1957.Adventures in tactile literacy. Geldard, Frank A. ''American Psychologist''. 12(3), Mar 1957, 115–124. It is a tactile system based on both practical considerations and on results from a set of controlled psychophysical experiments. Vibratese was composed of 45 basic elements, the tactile equivalent of numerals and letters. The entire English alphabet and numerals 0 to 9 could be communicated this way. Geldard reported that with proper training, rates of more than 35 words per minute Words per minute, commonly abbreviated wpm (sometimes uppercased WPM), is a measure of words processed in a minute, often used as a measurement of the speed of typing, reading or Morse code sending and receiving.

Somatosensory System
In physiology, the somatosensory system is the network of neural structures in the brain and body that produce the perception of touch (haptic perception), as well as temperature (thermoception), body position (proprioception), and pain. It is a subset of the sensory nervous system, which also represents visual, auditory, olfactory, and gustatory stimuli. Somatosensation begins when mechano- and thermosensitive structures in the skin or internal organs sense physical stimuli such as pressure on the skin (see mechanotransduction, nociception). Activation of these structures, or receptors, leads to activation of peripheral sensory neurons that convey signals to the spinal cord as patterns of action potentials. Sensory information is then processed locally in the spinal cord to drive reflexes, and is also conveyed to the brain for conscious perception of touch and proprioception. Note, somatosensory information from the face and head enters the brain through periphera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tactile Alphabets
A tactile alphabet is a system for writing material that the blind can read by touch. While currently the Braille system is the most popular and some materials have been prepared in Moon type, historically, many other tactile alphabets have existed: *Systems based on embossed Roman letters: **Moon type **Valentin Haüy's system (in italic style) **James Gall's "triangular alphabet", using both capital and lower-case, which was used in 1826 in the first embossed books published in English ** Edmund Frye's system (capital letters only) ** John Alston's system (capital letters only) ** Jacob Snider, Jr.'s system, using rounded letters similar to Haüy's system, which was used in a publication of the Gospel of Mark in 1834, the first embossed book in the United States. **Samuel Gridley Howe's Boston Line using lowercase angular letters, influenced by Gall's system but more closely resembling standard Roman letters ** Julius Reinhold Friedlander's Philadelphia Line, using all capital ...

American Psychologist
''American Psychologist'' is a peer-reviewed academic journal published by the American Psychological Association. The journal publishes articles of broad interest to psychologists, including empirical reports and scholarly reviews covering science, practice, education, and policy, and occasionally publishes special issues on relevant topics in the field of psychology. The editor-in-chief is Harris Cooper (Duke University). The journal has implemented the Transparency and Openness Promotion (TOP) Guidelines that provide structure to research planning and reporting and aim to make research more transparent, accessible, and reproducible. Abstracting and indexing The journal is abstracted and indexed in: According to the ''Journal Citation Reports'', the journal has a 2021 impact factor of 16.358.

Psychophysics
Psychophysics quantitatively investigates the relationship between physical stimuli and the sensations and perceptions they produce. Psychophysics has been described as "the scientific study of the relation between stimulus and sensation" or, more completely, as "the analysis of perceptual processes by studying the effect on a subject's experience or behaviour of systematically varying the properties of a stimulus along one or more physical dimensions". ''Psychophysics'' also refers to a general class of methods that can be applied to study a perceptual system. Modern applications rely heavily on threshold measurement, ideal observer analysis, and signal detection theory. Psychophysics has widespread and important practical applications. For example, in the study of digital signal processing, psychophysics has informed the development of models and methods of lossy compression. These models explain why humans perceive very little loss of signal quality when audio and video sign ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
English Alphabet
The alphabet for Modern English is a Latin-script alphabet consisting of 26 letters, each having an upper- and lower-case form. The word ''alphabet'' is a compound of the first two letters of the Greek alphabet, '' alpha'' and '' beta''. The alphabet originated around the 7th century CE to write Old English from Latin script. Since then, letters have been added or removed to give the current letters: The exact shape of printed letters varies depending on the typeface (and font), and the standard printed form may differ significantly from the shape of handwritten letters (which varies between individuals), especially cursive. English Vowels and English Consonants. The English alphabet has 6 vowels and 20 consonants. Written English has a large number of digraphs (e.g., ''would'', ''beak'', ''moat''); it stands out (almost uniquely) as a European language without diacritics in native words. The only exceptions are: * a diaeresis (e.g., "coöperation") may be us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Words Per Minute
Words per minute, commonly abbreviated wpm (sometimes uppercased WPM), is a measure of words processed in a minute, often used as a measurement of the speed of typing, reading or Morse code sending and receiving. Alphanumeric entry Since words vary in length, for the purpose of measurement of text entry the definition of each "word" is often standardized to be five characters or keystrokes long in English, including spaces and punctuation. For example, under such a method applied to plain English text the phrase "I run" counts as one word, but "rhinoceros" and "let's talk" would both count as two. Karat et al. found in one study of average computer users in 1999 that the average rate for transcription was 32.5 words per minute, and 19.0 words per minute for composition. In the same study, when the group was divided into "fast", "moderate", and "slow" groups, the average speeds were 40 wpm, 35 wpm, and 23 wpm, respectively. With the onset of the era of desktop computers, fast ty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
