In place of clicking on the touchpad for the Cases, I would boost in response to the visual incitements that would be linked with a reflex hammer with an accelerometer; the reflex hammer would move appropriately to the carrying of the picture on the screen by a programmed mechanical device. I wouldn’t use the reflex hammer’s sound however; it’s purely there to compute my reaction times (time of highest acceleration of movement of the reflex hammer deducted by time of reflex) instead of using the computer’s software at figuring reaction times, since I think the software is defective.
