I’ve been trying to think of other uses for the system. I’m wondering about this:

What use could a teacher make of a locator system, if students could identify their location and desire to be singled out for a moment, by simply clapping once?

In a big auditorium, a spotlight could track over to the student, who could then ask a question.

And/or, directional microphones could zero in on the student so the question could be played on the PA system.

I love the idea of accidentally triggering this system.

You're trying to catch a fly that's been tormenting you. You clap your hands together to catch it, but it slips out. The motors on the spotlight whir. "No no no, cancel cancel!" It's too late. Your hunt now has an audience. The spotlight is on you. Your classmates are calling out when they see the fly, cheering your swats, and groaning when you miss. Even the professor is silently praying for your victory so they might be able to regain some semblance of control over the class.
