A robot can monitor students’ engagement and modify its teaching to keep students focused, reports New Scientist.
University of Wisconsin researchers programmed a Wakamaru humanoid robot to tell students a story , one on one, while using a sensor to track brain signals.
During this story the robot raised its voice or used arm gestures to regain the student’s attention if the EEG levels dipped. These included pointing at itself or towards the listener — or using its arms to indicate a high mountain, for example.
Two other groups were tested but the robot either gave no cues, or sprinkled them randomly throughout the storytelling.
Asked about the story, the interactive robot’s students answered an average of 9 out of 14 questions correctly, compared with just 6.3 when the robot gave no cues.
