I have an eyesight problem and have trouble seeing presentations on the screen when I'm in conferences or in group meetings. I am currently using an application called Eye Glasses on my iPad for this purpose, which has a nice zoom capability but the problem is that I need to turn it very much toward myself to be able to focus on the presentation (which is usually shown on a screen located on the top of the wall).
I am now looking for a camera/webcam that I can mount on my macbook's screen or on my iPad with the following characteristics:
It must be tiny (ideally like a spy camera) so it doesn't catch the attention of the presenter or people who are sitting around me (most presenters are not comfortable with being on a camera)
It must have zoom capability so I can zoom in depending on my distance from the screen
It must have tilt capability (adjustable angle) so I can focus on the presentation depending on my vertical distance from the screen by just turning the camera (without having to adjust the angle of my macbook's screen or my iPad).
I need to emphasize that I do NOT need to record the presentation. Just seeing the screen would be more than enough for me.
Any ideas as to what options I may have?
