5. The system of claim 4 wherein the second sensor produces a second signal indicative of the interaction between the person and the workspace of the electronic device that places the object in the workspace;

wherein the processor receives the second signal from the second sensor and incorporates the second signal into the data indicative of the person'"'"'s use of the electronic device.

6. The system of claim 5 wherein the second sensor is an activity sensor coupled to a door of the workspace, the activity sensor monitors the patient'"'"'s operation of the door to access the workspace.

7. The system of claim 5 wherein the second sensor is a pressure transducer, the pressure transducer monitors the placement of the object in the workspace.

8. The system of claim 7 wherein the evaluation of the cognitive ability of the person by the remote monitoring station comprises evaluating the data indicative of the person'"'"'s use of the electronic device according to a predetermined order of interactions between the person and the electronic device.

9. The system of claim 8 wherein the predetermined order comprises placing the object in the workspace and starting the electronic device.

10. The system of claim 9 wherein the remote monitoring station analyzes the data with a technique selected from a list comprising:

an accuracy of the series of inputs received by the user interface, an accuracy of the person'"'"'s use of the electronic device compared to the predetermined order, and a temporal length of the person'"'"'s interactions with the device.

11. A system for monitoring and evaluating the cognitive ability of a remotely located person, the system comprising:

a plurality of appliances distributed throughout the domicile of a person, each appliance including;

a user interface that receives a series of inputs from the person, wherein the series of inputs define the operation of the appliance;

a first sensor that monitors the series of inputs received by the user interface of the appliance and produces a first signal indicative of the series of inputs;
