Wow, this list is great. I had no idea this was done already! What are the
details of the phone that does this?
I'm interested because I thought I had invented chording keypad typing! ah
well - I found similar USA patents as well. Now I'll be happy if my future
phone has this feature (though of course I hope they use my simply brilliant
But enough crying on your shoulders. Here's my contribution:
During my design process I did some crude tests and estimated a large speed
improvement using chording keypads for cell phone text entry. I claimed: "95%
of first-time users will double their old typing speed within five minutes of
using Phone3. After 2 weeks of usage, 80% users will triple their old speed,
to about 10 words per minute - that's 25% of a full QWERTY keyboard." Mind
you, those estimates are crude indeed, so don't be relying on them for
Another interesting source for text & data entry is T9, the word-completion
software that many US cellphones licensed (dunno about the rest of the world).
T9 was marketed (invented? I think not, but am not sure) by Tegis Corporation
www.tegis.com, which was purchased outright last year.
