We design, develop, study, and deploy human-AI intelligent interactive systems to enhance the accessibility of the real world and the digital world. We empower people to interact with technology through usage, customization, and creation. By doing so, we highlight the unique needs of people (e.g., people with disabilities) and the importance of designing for a long-tail of needs, so that technologies can best support them.

📢📢 I am recruiting PhD students to join the UMich Human-AI Lab, focusing on AI & Accessibility, and multimodal AR systems. If you are interested in the type of work we do, e.g., ProgramAlly, WorldScribe, SoundShift, BrushLens, Please apply!

Anhong Guo is an Assistant Professor in Computer Science & Engineering at the University of Michigan, also affiliated with the School of Information. His research is at the intersection of human-computer interaction and artificial intelligence, which combines human and machine intelligence to create interactive systems for accessibility, collaboration, and beyond. His research has won best paper and artifact awards at top conferences including CHI, UIST, ASSETS, and MobileHCI. He is a Google Research Scholar, a Forbes' 30 Under 30 Scientist, an inaugural Snap Inc. Research Fellow, and a Swartz Innovation Fellow for Entrepreneurship. Anhong holds a Ph.D. in Human-Computer Interaction from Carnegie Mellon University, a Master’s in HCI from Georgia Tech, and a Bachelor's in Electronic Information Engineering from BUPT.

ProgramAlly is an end-user programming tool for creating visual information filtering programs. The figure shows a diagram of how programs are run. For the example program 'find NUMBER on BUS', the app first looks for buses in the frame. Then, if a bus is found, the image is cropped to just contain the bus. In the cropped frame, text detection will be used to look for numbers.

CustomAD interface consists of a video player (left), which allows users to play, pause, and seek the video, and a customization pane (right) where users can customize the properties of ADs. The customization properties are grouped into content settings and presentation settings. The content customization adjusts the script's content as users change the ADs length and emphasis. In presentation customization, users could adjust speed, voice, tone, gender, and grammatical syntax of the ADs to change how the ADs are read out. Users can also toggle the ADs on and off.

BrushLens is a phone case with actuators that recognize screen elements, and use actuators to touch the screen on behalf of the user. It shows a user uses BrushLens to ``Brush'' on the touchscreen, and the actuator will touch if it is precisely on top of the button.

An illustration of VRGit. A History Graph (HG) that represents non-linear version history is anchored on the user’s left arm, where each node is a 3D miniature of that version. Inside each miniature, objects are highlighted using color coding if they are changed compared to the previous version. Mini avatars are anchored in the HG to represent which version users are in. Users can also create portals to monitor other users’ first-person views. A shared history visualization facilitates group discussion by anchoring the HG on a surface and allowing users to preview a version and reuse objects collaboratively.

A decision tree to predict the instances on which the Face API gender classifier is likely to make a mistake based on meta-attributes of the data. Each node of the tree is labeled by the counts of correct and wrong instances belonging to the clusters. Nodes are colored to represent the relative error rate, green shades for lower error rates and red shades for higher error rates.

The image shows an example of a common flatten the curve info-graphic. A tall peak indicates the height of the pandemic if left unchecked, and a shorter spread out curve depicts the effects of social distancing efforts.
