Abstract:

A system for acquiring feedback from an audience, such as a group of participants in an educational class or a business meeting. The system includes a camera that is controlled to capture an image of the group of participants. Each participant may be provided with a set of encoded objects that both reflect responses that can be selected by the participant and the identity of the participant. These objects may be encoded with a pattern that facilitates computerized recognition in the image of the response selected by the participant and participant identifier. Based on information acquired from the image, the system can automatically, or with user input, analyze responses from the group of participants.
