Vibration

Proprioception is the sense which provides us with information regarding the position, orientation and location of our body and vibration is highly stimulating to our proprioceptive sense. Vibrating toys tend to be inexpensive, so consider investing in rechargable batteries as vibration does quickly drain power. Many of our vibrating toys are "momentary" ie they operated by applying pressure to a switch, and when released the vibration ceases, encouraging interaction (& saving batteries). While vibration is very popular with many people, it is worth taking great care when introducing vibration to a new user as part of the attraction is the surprising ticklish vibrancy, which can be alarming.
