I am an elementary physical eduction teacher in NJ. Right now students are completely dependent on me to scan the plickers. I have created "plicker necklaces" for my students and would like for them to be completely independent during a lesson and scan/answer a question whenever they have completed a task. If I was able to use a forward facing camera on an iPad (or similar device) or set up a laptop as a station, this would allow me to continue instruction uninterrupted as well as tailor my lesson for the students that seem to be struggling cognitively. When students are using this mode, all of the student's answers will be invisible so students cant copy off one another.
