Figure 1. Scheme of the u-healthcare service using a voice inception IT solution.

The participants in the u-healthcare group are educated about how to use the u-healthcare service. They are instructed to input their self-measured glucose levels into the u-healthcare service system using two alternative channels. (1) Channel 1 uses a mobile phone or landline, and it is possible to enter the health data through voice with ARS or touch pad tone. (2) Channel 2 uses the Web site in a conventional way, in which the user logs in to the disease-management Web site by typing the information directly into the patient’s administration page. Data input is automatically transmitted to the main server in the u-healthcare center and then tailored messages automatically generated from the CDSS rule engine are transmitted back to their phones instantly as a voice service or to their personal page on the Web site and stored in the u-healthcare system. For dietary feedback, participants are educated to give information on their food intake via phone. They are also able to upload a food diary or a picture of a food on the health data input page on the Web site. In the Web site, a list of each participant’s favorite food is uploaded by a dietician to help patient click on what and how much they eat. Nutritionists directly analyze the customer-specific dietary problems through the analysis program called CAN-Pro 4.0 (Korean nutrition Society). The results from the CAN-Pro software are displayed automatically on the Web site, and the participants can find detailed information about their dietary pattern or, if necessary, a nutritionist directly provides direct consultations via the phone.
