Pen Based Interfaces and Handwriting Recognition

Pen on paper is a natural recording mechanism that humans have developed for several centuries. Our research focuses on the development of recognition technology, standards and applications of pen input in the context of emerging markets such as India.

Research areas:

• Handwriting recognition
  - Character and gesture recognition
  - Constrained Handwritten Word Recognition
  - Personalization and Adaptation
  - Handwriting recognition for Indic scripts
  - Analysis of writing styles
  - Linguistic Resources for Online HWR
  - Toolkits for handwriting recognition (Lipi Toolkit)

• Standards
  - Representation of digital ink (W3C InkML)
  - Representation of annotated datasets of handwriting, (Unipen XML)

• Applications
  - Pen-based form filling
  - Handwriting-based text input methods for Indic scripts
  - Collaborative inking
