Measuring Instruments

Objective measurements

In terms of objective measurements, we will simply count how many mistakes the user makes. In the evaluation, we plan on using a smarter robot, and a less smart robot. by comparing the number of mistakes between the two, we can quantify whether or not the "smarter" robot is actually so.

Subjective measurements

Since there are already many tried and true methods of subjective evaluation, we will make use of those to evaluate the system. The system usability scale [citation] will be uses to assess how usable the users find the system to be. As a way of measuring whether the users are satisfies with the outcome, and to check how the interaction affects their mood, we will use a short, custom-made questionnaire which asks a few questions related to this.
