Eye tracking with automated instructions

Hi everyone

I am new here!

I am doing an eye-tracking study. I am looking for info on how I can do experiments with frequent pauses and triggers. I want to automate the experiment instructions without programming the eye-tracking system. I am thinking of the best way to command the participant to perform different tasks (all in one video) when to start and stop for each of the different tasks. I will have someone wearing a head-mounted tracking device to look at an object as the starting point and then the person will look and search for another object when prompted by a system. Once detected, the system will give a stop signal to return to the starting position. There will be repeated cycles of looking at a baseline object, start signal, look at object of interest, detection, stop signal, dead time return to the baseline object. I really want a system that can integrate this into the eye tracking system without the need to write code
