A system for providing a virtual play environment to assist children with physical and/or cognitive impairments is described. The system includes a central processing unit, a selection device connected with the central processing unit, a computer memory connected with the central processing unit for storing object definitions and operational rules, and a visual display device connected with the central processing unit for displaying a visual image of a defined object and the actions of the defined object when it is selected by the user. Each object definition includes a plurality of attributes, such as an encoded visual image of a physical object, a binding variable for indicating whether the object is bindable to a second object, a moveability variable for indicating whether the object is moveable within the play environment, a list of other objects with which an object is bindable, a selectability variable for indicating whether the object is selectable for an activity, and instructions defining an action procedure to be followed by the central processing unit when the object is selected. The operational rules define a sequence of steps to be performed by the central processing unit to effect actions of defined objects in response to the selection device.
