The sense of touch is intrinsically linked to motor areas of the brain and is also arranged somotopically.  This means that our sense of touch is wired with an intuitive mapping of direction and spatial awareness. Thus, tactile cueing is particularly well suited to providing directional, guidance and communication cues.   

Tactile cueing offers the advantages of omni-presence (they are always available to the user with few competing demands for the tactile channel) and omni-directionality (the user does not need to be looking in a specific place to receive tactile feedback) and they can be applied at almost any place on the body – in effect, acting as “eyes in the back of the head”.

EAI’s ATAC™ systems consist of several technology components that can be combined and configured (by EAI or the user) to implement various applications:

• Wearable and seat mounted vibrotactile transducers and arrays.
• Tactor controllers.
• Wired and wireless interface.
• Application and development software.
