Calculator to computer display?

Postby khanh93 » Sat Sep 04, 2010 9:26 pm UTC

I'm going to start a series of presentations on how to use the TI-89 to my AP Calculus class on Tuesday. I've got the content of my lessons planned out, but I want a way to show the actual calculator display to the class. I know software exists to stream the display to the computer, but my limited google-fu has only netted me the official TI-Connect software, which doesn't have that capability as far as I can tell. Does anybody here know of/have experience with the software that I am looking for?

I'm thinking an emulator would be a good backup plan. Do the forumgoers agree?

What I did with my TI-84 was that I connected it to TI Connect, selected the screen capture option, and selected the auto refresh option. Resize the screen as needed, et voilà! The picture of the screen on your computer updates as you use the calculator.

Hope that helped!

My high school calculus teacher had a tool that plugged a TI into a TV. Possibly this.

Thank you Heady! TI-Connect didn't register my calculator when I first installed it, but that's a problem I'll have to solve for myself.

Nyeguy, that's a nifty device, but doesn't help me.

My teachers would use a document camera, so if the classroom you're using has one, that's just another option.

I've seen those used before, kestrel, but all i have is a computer connected to a projector.

I've got the TI-Connect software up, but I'm not seeing any auto refresh option. The help documents offered no insight. Do you remember how to activate this? I'm currently working on a series of still capture I can use to teach the lesson, but a live feed is still a nice option to have.

my teacher had something that displayed the screen of the calculator in such a way that is could be used with an overhead, though i imagine that it may be rare and/or pricy.

Wouldn't the emulator actually be a better option so you can show everyone which buttons to press?

I thought so too, but the emulator was pretty crappy. It didn't have the whole OS, which meant that I couldn't hit my first point of interest. The button graphics were really poor quality, so it wouldn't have helped much for the class to see. I ended up pasting calculator screenshots onto a picture of the calculator. The finished presentation, if anybody wants to see.
