A Ubiquitous Digital Writing System
Using MEMS Motion Sensing Technology
一種應用微機電(MEMS)運動傳感技術的通用數碼書寫系統
"Electronic Whiteboard"
and "Digital Pen" are new paradigms
in the office automation industry that may someday
completely replace the computer keyboard, which is
still the preferred human-to-computer input device.
These new technological devices aim to capture human
hand writing or drawing motions in real-time and store
the human motion strokes for character recognition
or information retrieval at a later time. Products
which aspire to capture this new market have begun
to surface commercially in the last 2 years. However,
existing technologies are still hampered by at least
two problems: 1) requirement of specialized and bulky
accessories (e.g., special white boards or papers
are need) that hinder the technologies for becoming
highly popular; 2) relative high cost of the products
which makes them inaccessible to many professional
or home users.
For this project, we will develop
a novel Ubiquitous Digital Writing System
based on MEMS sensing and low-power wireless circuit
technologies. The system will combine with a mobile
computing host to enable a completely new solution
for mobile digital data input media. This novel system
will provide end-users with lower cost products and
allow them to have total freedom to use the new paradigm
technology ubiquitously, i.e., they can use the system
anywhere and on any surface, without the need for
specialized papers or whiteboards. By merging DAKA's
extensive electronic device manufacturing experience
in the past 10 years, and CUHK's renowned Micro Input
Devices System (MIDS) technology, our team intends
to deliver a fully functional prototype of the Ubiquitous
Digital Writing System within 2 years.
