TouchKo's (now Wacom Company Ltd.) spatial capacitive "touchscreen", can sense fingers at a small distance, so you do not get your display greasy, and can unlike some touchscreens, be operated with gloves.

Thought educational example:
- If the Neo1973 detect a finger have pressed the screen, the Neo1973 should vibrate two short times and reply one of these:
- "You can touch my screen, but I also understand close proximity finger sign language.".
- "Do not touch my screen, I understand close proximity finger sign language.".
