We examined the effects of orientation and gaze behaviors for a robot during small group conversations. Our findings suggested that these behaviors can mutually influece how people perceive them.
We explored reinforcement learning techniques to find good policies to control the orientation of a mobile robot during social group conversations.
We proposed an alternating optimization procedure to detect F-formations typical of group conversations and estimate the lower body orientation of people in a scene.
We explored using a social role-playing game to study human-robot interactions. We investigated human spatial behavior and the effects of the role of a robot in the interactions.
We designed and built an expresive furniture robot platform. With this platform, we then explored the impact of a co-located sidekick on human-robot interactions.
We explored 3D printing physical device controls whose tactile response and shape can be manipulated programmatically through pneumatic actuation.
We investigated factors that can influence an operator's trust of robots, such as variable autonomy reliability, and worked towards creating a model of trust for human-robot interaction.
We proposed an assisted photography framework to help visually impaired users properly aim a camera and evaluated our implementation in the context of documenting public transportation accessibility.
We studied the effect of robot deception in the context of a multi-player reflex game. The robot was designed to deceive game players with the hope that they would want to play longer and with more interest while eating healthy food.
We proposed a real-time video smoothing approach for the stabilization of videos captured from small helicopter platforms. We also conducted field experiments to test our implementation.
