Interactive rigid panel on the floor | interactive carpet

Hi there,

I have to realise an installation where the user steps on a rigid platform (40x40x2 cm dimensions ideally) placed of the floor, like an”interactive carpets”, to activate a video on the wall. The playing starts when the user steps on the platform on the floor and stops when he will leave.

Is there any existing hardware in the market that I could buy for this solution (To send the data in touch designer to play the content) or do I have to build the platform and integrate with sensors and arduino?

Many thanks in advance
