UI-Button / continue flow

Dear ,

I'm designing a platform to control a robot with camera. But when i click in the ñeft button for example , it only do one sequence and i should click on another way to do another sequence. But for this context (robot) i would like to click the button and maintain it to drive the robot and the camera.
What solution can i have to use my tablet in use the button to drive the robot in the camera without interruption?

Regards
