This is a software design with algorithm to process a series of strokes or radicals to form Chinese words. The user interface also allows for easy access with eye-gaze selection methods – direct access and dwelling. It should also allow switch-scanning access methods in future.
The target users are all potential users of Augmentative and Alternative Communication means due to loss of speech and physical movements.
Given the ease of use, it can potentially be used with mainstream devices for all who require stroke input method.
We are looking for commercial partners who are able to develop this software further and able to interface it with various operating systems and access methods.
TECHNOLOGY FEATURES & SPECIFICATIONS
The first prototype contains the following key technical features:
Grouping of all strokes into 5 basic groups
Predictive text choices based on first few key strokes
Wildcard key stroke
User interface design
Basic keyboard with basic keys
Advanced keyboard with additional common character parts
Settings adjustment for size, speed etc
Primary application area:
Patients who are unable to speak and move their hands due to some neurological conditions or medical issues often require alternative communication means eg. using their eyes to control a computer and type out messages.
Existing software and devices so far only support patients who are either literate in English or able to type Mandarin characters with “han yu pin yin”. However, there is a population of such patients who is Chinese literate who now then have no means to communicate as they were used to writing out the characters on paper and pen, or drawing on their phones.
With this software, these patients can then communicate and access technology more easily.
Given the ease of use, it can potentially be used with all mainstream devices for anyone who require stroke input method to type out Chinese characters. The word prediction function can be also helpful for those who only remember part of the Chinese characters compared to searching through words that sound alike with “han yu pin yin” input.
Benefits of this technology for the users:
Reduce need to learn han yu pin yin
Challenging due to unfamiliarity with English alphabets and transcription of sounds
Reduce dependence on communication partners
Customized communication charts inadequate for communication partners to predict user’s responses
Reduce frustration in both user and their communication partners
Increase independence and autonomy
Users can participate actively in decision making processes
Reduce length of stay in hospital
Improve care outcomes
Reduce communication breakdown between healthcare professionals and patients
