EADL feedback to the user may be visual or auditory.
Direct connection implies that other devices are connected to the EADL unit.
Other factors to include when considering equipment are the place(s) the EADL will be used, the layout and size of each area, the devices to be controlled, the electrical condition of the controlled environment, the bed/chair mounting, the switch type, the required integration with existing assistive technology equipment, and the particular EADL limitations and benefits.
The basic cost of a full EADL system can range from $3,500 to $6,000.
Due to lack of funding in general, technology transfer into EADL devices has been slow.
For the EADL market to change drastically in the United States, funding for the devices will likely need to become more accepted.
Since many of these devices cannot perform EADL functions, some growth in this area may be expected.
Common types of electrical appliances controlled by EADLs are telephones, lights, door openers, door locks, fans, drapes, blinds, beds, audiovisual equipment, home climate controls, call systems, and security cameras.
