Workshop Goals

A growing number of computer vision researchers are becoming interested in applications for persons with visual impairments (VI), including low vision and blindness. Recent advances in algorithms, sensors and embedded computing hold the promise to enable computer vision technology that can address the needs of this disadvantaged population. Developing assistive tools for the VI community requires informed knowledge of several relevant human factor and technological issues:

  1. The actual problems impairing the daily quality of life of these users;
  2. An awareness of existing assistive aids;
  3. A realistic understanding of the possibilities offered by the available interfaces (visual, audio, tactile);
  4. A system-level approach to the design of algorithms and hardware that takes into consideration practical factors such as size, speed and cost.

This one-day workshop aims to bring together computer vision researchers and experts in VI rehabilitation and assistive technology. Three invited keynote talks given by VI experts will provide an overview of assistive technology for persons with disabilities, concentrating on the needs of the VI community. Attendance by VI experts outside the computer vision community will also be encouraged. By addressing the context in which assistive technology is used and designed, the workshop seeks to help researchers identify fruitful areas of overlap between the most pressing needs of the VI population and the capabilities of computer vision technology. A general discussion session at the end of the workshop will facilitate the exchange of ideas between computer vision researchers and VI experts.

Financial Support

A limited amount of financial support for attendees of CVAVI'05 is available thanks to a grant from the National Science Foundation. There are two (exclusive) types of support:

  1. Workshop fees. Only workshop attendees who are not
    participating in the main CVPR conference qualify for this type of support. Note that the workshop fees are already included in the main conference fees for CVPR.
  2. Lodging for one day at the conference hotel. Attendees who are also attending CVPR but need an extra day to participate to the workshop qualify for this type of support.

In order to apply for financial support, you need to send an email to Roberto Manduchi ( stating:

  • Your name, institution, and position;
  • Which type of support you are applying for;
  • A statement describing the reasons why attending the workshop is an important professional activity for you;
  • If you are applying for the first type of support (workshop
    fees), a statement attesting that you are not registering for the CVPR main conference.

Applications must be received by May 20 to be considered.
