Which artist uses computer vision to enhance user interaction with their work?

David Rokeby is known for his innovative use of computer vision to enhance user interaction with his art. He explores the intersections of technology and art, particularly through installations that utilize computer vision to create dynamic interactions based on audience presence and movement. This approach allows viewers to engage with the artwork in a participatory manner, making the experience fluid and responsive.

Rokeby's work often investigates themes such as perception and the role of technology in shaping our understanding of the world. By employing computer vision, he creates a dialogue between the audience and the artwork, encouraging an immersive experience that can change based on user input and interaction.

Other artists listed may explore different thematic or technological approaches in their works but do not prominently feature computer vision in the same way Rokeby does. Thus, his unique integration of this technology with interactive design is what makes him the correct answer in this context.
