Keyboards for efficient input on PDAs.
See some of the best
keyboards. Words are formed by gliding the stylus from one letter
to the next. The boards were formed using simulated annealing with
letter frequencies from common English (s and z
represent leading and trailing spaces, though either can be used for
'space', or a twiddle back over them for double space). Generally the
keys naturally align themselves to a hexagonal grid.

See my Study Group Ideas Page for random seminars and discussion groups that I am or have in the pass been interested in running, given sufficient interest.
See my Projects Ideas Page for random ideas that I am not currently pursuing, but would be interested in working with others on, or seeing their progress occur.
New Sliderule Design: Sliderules are in
many ways as powerful as scientific calculators, capable of applying
several functions and inverse functions. My idea is to have a
paper-thin kind, formed with a opaque "back" and a transparent
"window", with the same or similar functions. Functions can be
applied by lining up the appropriate scales (rather than with a
slider), and because the two can be disconnected, one can combine
ideas from sectors for trigonometric functions. Here is C code to generate a Postscript file to be printed on paper and
transparency. More scales/functions need to be added.
