SolidSketch is a solid modeling program that enables users to rapidly construct 3D models through sketch and multi-touch input. The interaction design principles of SolidSketch are based on the cognitive science theory of enaction. This paper uses the enaction theory as a lens to describe why the interaction designs of conventional CAD tools often fail to support early stages of the design process. We argue enactive interactions would support design creativity by enabling rapid iteration and continuous feedback throughout a flexible design exploration.

Since its earliest days, flaming, trolling, harassment and abuse have plagued the Internet. Our aim is to computationally model abusive online behavior to build tools that help counter it, with the goal of making the Internet a more welcoming place. In particular, we look at a novel approach to identify online verbal abuse using cross-community linguistic similarities between posts on different communities. This work will enable a transformative new class of automated and semi-automated applications that depend on computationally generated abuse predictions.

Our AI agent (Frogger) explains its decisions in plain English—why do we need that? As Aritificial Intelligence (AI) becomes ubiquitous in our lives, there is a greater need for them to be explainable, especially to end-users who need not be AI experts. Come by to see how our system produces plausible rationales and understand how human perceptions of these rationales affect user acceptance and trust in AI systems.
