When establishing an Eyegaze communication board, there are two main parts to consider. First of all there is the communication board; this section contains all of the necessary vocabulary the individual will use when communicating. The words that comprise this communication board are all based on the user's preferences of what is most important to communicate. Most users have a variety of differences on their personal board, however many have some similarities. For example, "eat, drink, food" are basic needs that usually should be placed on each person's communication board. This part of the system is primarily placed in the tray of the user's wheelchair.

Secondly, a clear acrylic board comprising of encoded material is held upright near the individual's face. The information that is encoded can be symbolized as colors, letters, and/or numbers (depending upon the preference of each individual).
