2026 VizWiz Grand Challenge Workshop

Sep 2025 update: Our evaluation servers are currently under transition maintenance. For offline benchmarking services, please read this page.

Overview

Our goal for this workshop is to educate researchers about the technological needs of people with vision impairments while empowering researchers to improve algorithms to meet these needs. A key component of this event will be to track progress on four dataset challenges, where the tasks are to locate objects in few-shot learning scenarios, ground all answers, locate all plausible region of focus, and locate and track object and part instances. The second key component of this event will be a discussion about current research and application issues, including invited speakers from both academia and industry who will share their experiences in building today’s state-of-the-art assistive technologies as well as designing next-generation tools.

Banner illustrating VizWiz Dataset Challenge tasks in four columns: (1) Few-shot localization of private objects, with examples like an empty pill bottle and a bank statement. (2) Grounding all answers, showing questions with multiple valid answers (e.g., identifying sugar type or airplane type). (3) Grounding all focus regions for visual questions, highlighting multiple regions linked to different answers (e.g., clock times, cleaning products, bird location). (4) Hierarchical instance tracking, showing sequential images tracking a pill bottle across views.

Submissions

We invite two types of submissions:

Challenge Submissions

We invite submissions about algorithms for the following four challenge tasks: locate objects in few-shot learning scenarios, ground all answers, locate all plausible region of focus, and locate and track object and part instances. We accept submissions for algorithms that are not published, currently under review, and already published.

The teams with the top-performing submissions will be invited to give short talks during the workshop.

Extended Abstracts

We invite submissions of extended abstracts on topics related to all challenge tasks as well as assistive technologies for people with visual impairments. Papers must be at most two pages (with references) and follow the CVPR format using the provided author kit. Reviewing will be single-blind and accepted papers will be presented as posters. We will accept submissions on work that is not published, currently under review, and already published. There will be no proceedings. Please send your extended abstracts to workshop@vizwiz.org.

Please note that we will require all camera-ready content to be accessible via a screen reader. Given that making accessible PDFs and presentations may be a new process for some authors, we will host training sessions beforehand to both educate and assist all authors to succeed in making their content accessible.
