>>32591It was both more precise and more responsive than gyro controls, since it didn't have to calculate position based on motion or anything, just mapping the cursor to the location given by the IR sensor. If you could whip across the screen in 1 frame, it would follow, with no less accuracy. Gyro gets confused too easily for that. You have to go much slower to accommodate its limits. IR only really runs into problems if there's outside IR sources interfering. One way I saw that happen was the actusl IR signal bouncing off the TV screen and the glass picture frames on the wall opposite. A little rearranging fixed the issue completely.
Look at VR headsets. Anything above the low end relies on IR because gyro based systems are too imprecise and unresponsive and will give you motion sickness.
