Using Cameras in a Classroom to Gauge Student Interest Levels

I’m surprised I didn’t think of this myself. To try to stop people from video taping movies in the theater, the industry are installing cameras to watch their audiences. The system uses machine vision systems to automatically detect when someone is using recording devices.

The next logical step is to also gauge audience reaction to the movies.

So with audience feed back does that mean we will get a whole string of identical movies that are tailored to produce a reaction?  Blech. Famous directors like Stanley Kubrick, didn’t really spend much time thinking about what their audience thought about things, they just wanted to make the best movie they could.  Art is not supposed to appeal to everyone, that’s what makes it special.  It’s that individual evaluation that I enjoy. Again, blech.

However, this could be a useful tool in the classroom!  Imagine a camera watching your class as you give a lecture.  It can keep track of how long a person is watching you, if they are mostly facedown in their computer, or if they are sleeping.  Most importantly, an instructor could go back and review their lecture and see what parts are most effective and provoked the most interest from their students.  That could be worth doing I think.

It’s not disruptive tech, but it could be helpful in the classroom!

    • In an effort to further combat piracy, some cinemas have incorporated the use of an infrared scanning system that detects recording devices in the audience and if detected, sounds an alarm to alert management. Now the company that offers those services, Aralia Systems, is working to enhance the system by incorporating technology which will scan and read the audiences’ physical expressions and emotions.
    • “Within the cinema industry this tool will feed powerful marketing data that will inform film directors, cinema advertisers and cinemas with useful data about what audiences enjoy and what adverts capture the most attention. By measuring emotion and movement film companies and cinema advertising agencies can learn so much from their audiences that will help to inform creativity and strategy,” Dr. Abdul Farooq from Machine Vision Lab told TorrentFreak.

  1. Hmm, in the classroom this could provide part of a more authentic on-going teacher evaluation program where the information gleaned could be used as a starting point for improvement and learning.

    • Oh I totally agree. It’s frustrating that our assessment methods are so crude and standardized!
