Each hand represents a 5-digit binary number (where a stretched finger represents 1 and otherwise 0), which needs to be converted into decimal.
The flavour text hints at Binary LEDs and in fact, each number is present in its manual alongside the colour of its hand.
The right arrows [they're not greater than signs!] and the numbers to their right tell you how many spaces to move to the right in the grid, bouncing back the other way if necessary.
By converting these numbers into letters using A1Z26, we get the answer to the puzzle.
