One of the core technologies we are investigating
is Ink Processing. The work deals with addressing issues
related to ink capture and streaming, ink processing, ink
rendering and ink archival and retrieval. These technologies
find roles in applications ranging from usable pen-based
interfaces for text input, pen-based form-filling, multimodal
systems and web-based collaboration using handwritten notes,
to name a few.
We are part of the W3C InkML working group
to create a device and platform independent representation
for digital ink, to support interoperability between different
pen-based devices.
Our research in this area focuses on::
- Algorithms for processing and analyzing digital ink
data, to make it more amenable to search, transmission,
organization and visualization
- Storing hand-input ink traces for handwriting recognition
- Streaming digital ink data between devices and software
components
- Gesture interpretation of digital ink
We participate in standards activities such as Digitial
Ink Markup Language (InkML) from W3C, and Unipen XML
(UPX) from International
Unipen Foundation, a standard for representation of
handwritten datasets.
