26		-We will evaluate the prototype's effectiveness at the end of the experiment, i.e whether interactive storytelling was beneficial as compared to non interactive storytelling. Thus, we follow summative evaluation. Using a questionnaire, we will try to assess the usefulness and effectiveness of the robot. Due to limited time of the course, this will be the last evaluation. However, in the absence of time constraints, we would need to do a formative evaluation to get feedback for the next versions of the robot.

Since we are comparing two robots, we follow summative evaluation. Using a questionnaire, we will try to assess the usefulness and effectiveness of the robot. Due to limited time of the course, this will be the last evaluation. However, in the absence of time constraints, we would need to do a formative evaluation to get feedback for the next versions of the robot.

31	31	We present a low fidelity prototype of the robot, which means a simple demonstration of the initial stages of the robot, meant for formative feedback. We wizard-of-oz the approach, and for now just present one story (in interactive and non interactive modes) for purposes of the experiment. The final robot is expected to have various templates of stories.
