## 3 Results and Discussion
### Results from the Modified UCD Methods  
In the focus groups and the personal interviews, we used the MedReminder prototype developed for an interactive TV environment. Two focus groups were organized. After each focus group, we had personal interviews with the participants. Nine participants took part in the first focus group and three of them took part in the second focus group. Eight out of nine participants in the first focus group were married couples, whereas the participants in the second focus group were older woman, living alone. We found out that the people who were living alone were more enthusiastic about the MedReminder service, since they could not use \"living\" reminders as easily as the married couples did. Besides that, no significant gender or educational differences were observed in the study. Most of the participants found the MedReminder not to be complicated and to be really useful, especially for those who watch TV a lot. Eleven out of 12 participants reported they would like to use the MedReminder service in the future. Only one participant reported, \"It (the MedReminder service) is just another unnecessary complication for everyday life\". The focus groups and the personal interviews revealed some of MedReminder's disadvantages as well. Participants reported they had many problems when they were trying to set reminders for their medicine. However, when observing them as they were presenting their problems using the MedReminder service, we found they did not have problems with the service itself, but they were simply not fond of entering a lot of information in the system. Many study participants recommended that somebody else, for example, a physician, pharmacist or relative could set the medicine reminders on their behalf. They have suggested that setting the reminder in the doctor's office, immediately after the medicine prescription, or from the pharmacy, would be proper solutions to the problem. Another great concern that the study participants reported during the focus groups is what happens when the TV is off or the MedReminder user is not near the TV (he or she is in another room, or even away from home). As a possible solution, we presented them our idea to connect MedReminder with a mobile or stationary phone. They liked our idea and further suggested that when the TV is off, a reminder SMS should be sent to a mobile phone and/or a stationary phone should start ringing. At the end of the research study, the study participants filled out the SUS questionnaire. The result of the questionnaire is an easy-to-understand single-score ranging from zero (negative) to 100 (positive). The SUS single score that the MedReminder service obtained is 56.67 with standard deviation of 14.28. The lowest obtained SUS score in the user evaluation study was 35, whilst the highest SUS score was 85. In terms of adjective rating, according to the results obtained, the MedReminder service can be described as \"OK\" [17]. This grade means the study participants evaluated MedReminder as acceptable; however, additional improvements are needed. In the research study, we were particularly interested in the acceptance rate of new e-Health services among their intended users, in particular the acceptance rate of the MedReminder service among older adults. This is the main reason why we were especially looking for participants' opinions about item 1 in the SUS questionnaire, which states: \"I think that I would like to use this system frequently\". The results showed that seven participants out of 12 \"strongly agree\" or \"agree\" and only two participants \"did not agree\" with this statement, which confirms that most of the study participants would like to use the service more often. Additionally, study participants reported they believe that other people of their age would also like to use the application, especially if it is provided free ofcharge.
