| Interactive washing puff - it measures the distance between the machine and a wall. It also measures worker stress by measuring the loudness of workers' voices. |
| Smart spray for grafitti artists - this enables the painter to create a brush-like feeling by controlling the discharge rate (depending on the distance between the wall and the spray). |
| Smart detergent dispenser - it detects dirt by checking the brightness of the wall. |
