Abstract: A computer-based system for monitoring and improving a user's dietary compliance by providing the user with multiple forms of feedback designed to encourage adherence to a dietary program. In one embodiment the system comprises a personal computer having a commercially available telephony card and a cellular telephone carried by the user. The system automatically calls the user each evening and prompts the user to input whether the user adhered to the dietary program for each of that day's meals. The system accepts and stores the input, calculates whether the user is achieving their dietary goal, and gives the user positive or negative audio feedback based on whether the user is meeting their dietary compliance target.

Abstract: A computer-based system for monitoring and improving a user's compliance with a smoking cessation and relapse prevention program by providing the user with multiple forms of feedback designed to encourage adherence to the program. The system “calls” the user on the telephone at the end of each day and prompts the user to input the number of cigarettes smoked that day. The system accepts and stores the input and calculates whether the user is achieving their program goal (either a zero-cigarette goal, or a reduced-smoking goal under a step-down program), and gives positive or negative feedback based on whether the user is meeting their program goals.

Abstract: A computer-based system for monitoring and improving a user's exercise compliance by providing the user with multiple forms of feedback designed to encourage adherence to an exercise schedule. In one embodiment the system comprises a personal computer having a commercially available telephony card and a cellular telephone carried by the user. The system calls the user after each scheduled workout and prompts the user to input whether they completed the workout. The system accepts and stores the input, calculates whether the user is achieving their workout goal, and gives the user positive or negative audio feedback based on whether the user is meeting their workout adherence target.
