The implementation of the invention involves a conventional display window and a system for displaying a portion of said hierarchical tree within the borders of the window in combination with an implementation enabling a user to expand each nested displayed category into a displayed list of items in said category, and to collapse said displayed list back to each displayed category. There are means for scrolling said displayed hierarchy through said window. This invention provides for a set of displayed indicators, each representing a hidden expanded category in the hierarchical chain of a list of items displayed within said window. There is a further implementation associated with each displayed indicator enabling a user to select the indicator to collapse the hidden category represented by said indicator and thereby enable the display of the collapsed category within said window.

Computer controlled user interactive display interface implementation for tracking the organization of items in a hierarchical tree of nested categories

In a method for providing customized services to a person having a disability, a first message is transmitted by a wireless client device and is received by a server device. The client device is operable by the person with the disability. The first message is transmitted by using a close-range, standard-protocol radio signal. The server device sends a first response message to the client device by using the protocol. The first response identifies a contact phone number. The person with disability dials the contact phone number, thereby generating a second message that uniquely identifies the person. The server device receives the second message on the wireless carrier network. The server device performs a search on a database for a record matching the person. On finding a match, a second response is sent to the client device describing a list of customized services configured for the person with disabilities.
