I like to refer to text entry as a meta application. i.e. an
application that is used by most if not all other applications. That
is how integral it is to mobile computing.
The most fundamental shortcoming of a mobile device is the data entry
interface, as compared to the PC keyboard. We have tried to address
this problem.
To quote the little girl in the original Google video.
"My magic phone would have a keyboard that fits in my pocket"
The system design is rugged, reliable and accurate and eliminates the
biggest barrier to the acceptance of handwriting recognition as a
viable text-entry method. A recognition accuracy of 100%
Although the target demographic was the blind/visually impaired, the
system is also a viable text entry method for the following use-cases:
1) It is intuitive and provides 100% recognition accuracy of all
characters stroked
2) Since it is intuitive to stroke characters, there is zero seek time
i.e. the time taken to seek a character on a keyboard before pressing
the key. This can convert to high speeds of data entry
3) Does not need a stylus, and can be easily stroked by hand
4) Complements multitap and predictive text by providing gesture
recognition and relatively easy entry of special characters
5) For data entry in a dark area or while on the move when its
difficult to see the keys on the keyboard, or the phone is jerking
while travelling, when most handwriting recognition systems would give
a large error rate, and keyboard entry methods are difficult if not
impossible.
(And we all know that mobile data entry is generally done on the move)
6) Since special character entry is very fast compared to multitap or
predictive text and recognised with 100% accuracy as compared to other
handwriting recognition systems, it can serve as a programmers editor
where special characters form a large part of the vocabulary.
7) Can be implemented on hand wearable mobile devices where
conventional keypads are impractical to implement and use
8) In an emergency - send out an SOS message intuitively and reliably
when normal sighted access to the keyboard is not possible
