What is the ACE Lab?

The ACE Lab at the University of Washington is housed in The Information School and comprises students from information science and computer science doing original research in the field of Human-Computer Interaction (HCI). The lab is directed by Prof. Jacob O. Wobbrock.

Lab members create Accessible Computing Experiences, believing that interactive technologies should serve and enhance human experience for all people.

Lab members also create Advanced Computing Experiences, using artificial intelligence, machine learning, sensing, statistics, human factors, crowdsourcing, and rapid prototyping to build interactive systems that partner with users effectively.

Our past work has influenced accessibility on the iPhone, made gestures easy to design and implement, and been the basis for startup companies, among many other contributions.

ACE members are active in the larger DUB Group, the multi-departmental HCI and Design consortium widely regarded as one of the top research communities for HCI in the world. Some members are also part of UW CREATE, the Center for Research and Education on Accessible Technology and Experiences.


To understand and create advanced interactive technologies that improve people's access to and experience of computers and information, especially for people with disabilities.

Our Values

  1. Vision. "The world has arrived at an age of cheap complex devices of great reliability, and something is bound to come of it."   — Vannevar Bush (1945)

  2. Creativity. "The most dangerous phrase in the language is, 'We've always done it this way.' "   — Grace Hopper

  3. Elegance. "The stuff I design, if I'm successful, nobody will ever notice. Things will just work."   — Radia Perlman

  4. Utility. "The value of an idea lies in the using of it."   — Thomas Edison

  5. Inclusion. "Everybody has to be able to participate in a future that they want to live for. That's what technology can do."   — Dean Kamen

The Pointing Magnifier 2 is a "product-grade" rebuild of the original version from 2011. It is an area cursor that magnifies the contents beneath it in both visual and motor space, making targets easier to see and to click on. Useful for people with limited fine motor function and/or older adults. Check it out!
