The Elevator Push Button will have a floor number and a button in one and two separate forms, where only the floor numbers and buttons are discussed.
Button common material silver background white, black black background, black and white black and white four (dark color, color white background similar to white, black and white, no other discussion).
On the identification of the right side of the black on the right side of the black, black and white background black and white, text and background can form a large contrast, easier to identify. However, as shown in the picture on the left side of the BO silver white, then the recognition is relatively low, more difficult to see when the non-face. As the overall silver shown in S, there are similar problems.
After the press response analysis: click, the button needs to give "successful operation" of the immediate feedback, the form of feedback and the button material has a certain relationship. In the form of feedback, personally think that through the digital feedback is the optimal solution, describe the process of passing the elevator, should be: a certain target floor, looking for floor numbers, the corresponding operation of the number DazenElevator button to confirm the operation is successful, confirmed to reach the target floor, floor number is Through a clue. In the selected example, BOP is white text, after pressing, are digital lights, silver and black are isolated light perception, the bottom does not change, people's attention focused on the operation of the figures, and BO also through the outer ring "light leakage" processing to strengthen the feedback. E should be pressed after the entire button is lit, this is the only possible black and white button button feedback form, so the most intense change is the background changes, feedback enough, but slightly too far. B is to use only "light leakage" to push the feedback. S visual inspection is relatively easy to bring doubts exist, there is no gap outside the button, unlike the "light leakage" feedback, the operator can not immediately get "press success" feedback (outer ring green plastic is 0 Stressed that the button is not pressed the feedback), probably only through the elevator to move to judge.
