Projecting an image onto a mirror

[jjddd]

I need to do something for a project. Basically, I need to be able to project a clear image onto a mirror while still being able to use the mirror when the projector is not in use. Is there a way to do this/a cheap coating I can put on a mirror to accomplish this?
Thank you!

I don't know of any coatings, but perhaps some sort of portable screen or a sheet?

You would need a surface with a relatively high proportion of diffuse reflection in order to project an image on top of it. This will most likely result in it working rather poorly as a normal mirror.

Ah yes, I should have guessed that existed as I was looking up smart glass solutions not so long ago (it seems to be simply integrating a smart glass with a mirror). However, I do not know if this qualifies as "cheap".

Could you do something with lighting and a Pepper's Ghost arrangement? Old but impressive in some circs.

I guess it is an expensive crappy mirror and crappy screen. It is cheaper and more effective to keep the mirror and install a pull-down projection screen above the mirror. Or simply stick a big sheet of white paper to the mirror with some tape, when it is needed for projection.

You could do away with the mirror completely and use a large TV monitor array with a camera at the centre. In mirror mode, the camera would be the picture source. I see women using their smart phones in this way (in their cars on the way to work) and they don't need to carry a makeup mirror.
Unfortunately, not a 'cheap solution".
