b) Development of a practical method of extracting central motor commands from electromyograms by computer-programmed pulse density demodulation processing.

c) Coordination of multi-level data concerning the running action of legs, such as optical measurement and magnetic nuclear resonance imaging of the anatomical structure of the leg muscles, and testing of isokinetic muscle force for rotating related joints.

d) Investigation of the possibilities of reading printed letters, especially Japanese kanji characters, through auditory or tactile substitution of the visual function.

e) Analysis of language information visually transmitted by hand movements, and its application to the description of sign languages*.

f) A statistical survey on use of communication media by hearing impaired persons for participating social activities (A cooperative project with the National Rehabilitation Center for the Disabled, The Ministry of Health and Welfare, Japan).

g) International standardization of evaluation criteria for speech perception ability by use of electrical and tactile sensations in the hearing-impaired (under the auspices of the international joint research programs sponsored by The Ministry of Education, Science and Culture, Japan, and Waseda University).

h) Extensions for pathological speech of the IPA; International Phonetic Alphabet (revised to 1989 by the International Phonetic Association), based on studies such as analysis of lingual articulation by use of electro-palatography, classification of Japanese syllables including speech sound in loanwords, and selection of test materials for speech disorders.

i) Analysis of the nature of errors in various modes of performance of Japanese language such as listening, silent reading, speaking, reading aloud, writing and copying, made by adults having normal competence.

j) Methodological study on assessing the capabilities of techniques for speech processing and facilitating their effective use as man-machine interface through spoken language.

k) Editing teaching materials and developing systems for application of CAI strategy to foreign language learning.

l) Assistance to use of multi-media communication by sensory-impaired persons.
