· In very noisy environments where it is difficult to hear, virtually anything can be communicated as long as you can see each other’s hands. It is like touch-typing — you don’t even need to be looking at your own hand!
· In very quiet environments, a message can be passed without disturbing other people in the area. Even communicating across the room without talking or shouting is easy (assuming your eyesight is good enough to distinguish the codes).
· In hospitals when a person is incapacitated, and the method of communication is limited. Slight finger movement is all that is necessary to convey a message.
· In military situations, when pre-arranged hand signals are not sufficient.
· In texting, a touch-type method that does not require a keyboard (the app is forthcoming!).
· In total darkness or other situations where one cannot hear and/or see, by touching partner’s corresponding fingers.
It is also fun to practice during
long, boring meetings!
The basic method is to tap on a surface where the other person can see each fingertip making contact. Other methods are:
· The Monk – tapping fingertips of both hands together
· The Thinker – hand on face as if thinking about something
· The Charade – tapping on forearm
· The Pinch – instead of tapping on a surface, touch the tips of the fingers on the one hand to each other while keeping the other fingers apart. (e.g., a “B” would look like the gesture you make for “OK!”) This is much harder to do, not to mention, read! For single elements such as A, F, J, M, or O, bend only the appropriate finger.
