I give presentations while standing and need to switch PowerPoint slides. Only controlling the forward button would be fine. My challenge is that foot pedals are not optimal for standing because they require you balance on one leg while pressing. For a long presentation where I need to press sometimes as frequently as every sentence (to trigger animations) this gets pretty tiring.
I would like to have a way to remain more firmly planted and evenly balanced on both feet. I imagine making a small gesture like lifting the toes or heel of one foot would be more comfortable than pressing a pedal.
How can this be achieved reliably for both Windows and MacOS? I know there are LiDAR devices that sense gestures, but I think I need a physical button of some kind to make sure every gesture is perfectly registered.
Alternatively is there a device I could hold in my hand that’s so small that it’s invisible for my viewers who watch me via a webcam even when my hands are in the frame. Tapping two fingers together to trigger the gesture?
The main reason why I want the device to be invisible or out of the frame is to avoid distracting my viewers. My background (a plain wall) helps with this. I'm also very minimalist with my slides and avoid having anything that's not directly related to my message. With that in mind, I want all of my visible gestures to convey meaning rather than being used to switch slides.
Automated transitions will not work here because the audience may interrupt to ask questions and I may need to adapt the presentation as I go.
