Matthew's brother helped Matthew choose which activity he wanted to do by helping Matthew put the chosen object in a box. Once Matthew was confident of the system, he started to choose a week in advance what he would do next. They can include information about visitors, or enablers for different activities. Sighted people may cope well with pictures or photos. Some people will find symbols useful as they are small and discreet.
Some disabled people prefer a hook where objects can be hung up.
Object calendars or boxes must be placed where they will be used by everyone, and not overlooked. It may be preferable for people to move about with objects in bags, to afford them some privacy and to be more age-appropriate. To understand the environment Multiply disabled people are very dependent on carers communicating about key locations in the environment. People should not be moved or asked to move until they have been given some clue about where they are going. This also gives the person the opportunity to choose whether or not they wish to move.
