  2. Definition Environmental Control Units (also referred to as Electronic Aides to Daily Living ) are specialized assistive technologies designed to enable an individual to operate many household appliances and electronics if he or she can not use the standard controls. For example, if an individual can not access a standard light switch, an ECU could provide an alternative way for the individual to turn the lights on and off. Another example would be if someone had difficulty accessing and/or using the telephone. Once again, an ECU could provide a different way for the individual to use the telephone. ECU’s can also provide alternative controls for the television, cable box, DVD player, stereo, heating/air conditioning, fans, doors, etc.

  3. From Cook and Hussey, 1995

  4. CENTRAL PROCESSING UNIT INFRARED DEVICES: TV, DVD PLAYER, CABLE BOX, STEREO, ETC. USER DISPLAY TELEPHONE USER CONTROL INTERFACE X-10 MODULES/RECEIVERS AND OTHER X-10 INTERFACES The principal components of an ECU are also illustrated in the following block diagram: IR Radio Signal The User Display and User Control Interface constitute the human/technology interface

  5. X-10 control input module (left) and receivers (right)

  6. Two Common X-10 Input/Output Block Diagrams House Wiring X-10 Modules X-10 Transmitter Radio Signals X-10 Receiver House Wiring IR Signals IR Receiver/ IR to X-10 Converter X-10 Modules IR Transmitter

  7. TWO WAYS TO CATEGORIZE COMERCIALLY AVAILABLE ECU's: STAND ALONE SYSTEMS (PERFORM ECU FUNCTIONS ONLY) INTEGRATED SYSTEMS (PART OF OR INTEGRATED WITH OTHER ASSISTIVE TECHOLOGY)

  8. STAND ALONE SYSTEMS

  9. Switch Activated

  10. Big Button Remote Control

  11. INTEGRATED SYSTEMS

  12. ECU Integrated with Augmentative Communication

  13. Infrared (IR) Capabilities built into power wheelchair electronics:

  14. Telephone X-10 via house wiring IR ECU Radio frequency or IR signal USB Connection POWER WHEELCHAIR PERSONAL COMPUTER Any Control interface used to drive Any computer access technique

  15. FACTORS TO CONSIDER WHEN RECOMMENDING AN ENVIRONMENTAL CONTROL UNIT: * Client’s Goals (what does he or she wish to control) * What other assistive technology is utilized by the individual * Client’s prognosis (stable/progressive?) * Client’s cognition * Where is the system going to be used (home or work, in one room or throughout the house, etc.) * System reliability, flexibility and ease of operation * Local tech support for installation/configuration/service * Expense of the system and the funding source

  16. Thank you. Any Questions John Coltellaro MS, ATP coltellaroj@upmc.edu
