## 2 The Smart Angel Project
### Smart Angel and Time Management  
One of the two areas that we decided to address was time management. The typical user can read correctly the time on a clock and can usually say if a certain time has passed or if it is still in the future. What is difficult to manage is the time span needed to perform daily actions and routines. They need some help in deciding when it is time to start an action. For example, if a person has to be at the gym at 5 p.m., he will have to start packing the bag at 4:15 p.m. and leave home at 4:30 p.m.  
Smart Angel provides a daily agenda, in which the daily routines and activities are defined by the caregiver, often involving directly the end user. The daily program can then be modified by the end user within some constraints. For example, while the time for work is fixed, shopping can be done at any time, as long as the shop are opened. The agenda can be completely personalized according to the users' needs, with respect both to the interface and to the reminders, which have to be efficient but not too intrusive.  
During the day, the system will then automatically remind the user when it is time to start a certain activity. Multiple reminders are also possible, for example, the agenda can have a first reminder 15 min before an activity has to start and a second one five minutes before.  
For some important activities, the agenda will ask the users to confirm that they have actually done it by a specific time, for example, it is important that the shopping is done before the shops close, and the activity has to be remembered otherwise it will be impossible to organize the dinner.  
Time management has an impact also on mobility. Based on the current position in town, specific reminders may be needed, for example to help the person get to work on time in case he stops on the way for any reason. Moreover, according to the user's current position and to the estimated time needed to get back home, the system may remind its user when it is time to start on the way back.  
Furthermore, people with the Down syndrome, sometimes isolate themselves and become unaware of the world around them and of time going by. In these cases, a gentle reminder to help them get back on track may be very useful.  
The Smart Angel agenda is aimed at supporting autonomous living, it can be a valid tool not only for those people who live a mostly independent life, but also for those who occasionally have to stay for some time alone at home, even if they are living with their own families. They may have to manage some small activity, as getting ready for the gym, and the specific support for time management is very useful. Furthermore, for all those who move independently to reach, for example, their place of work, the agenda will help them not to be late.  
For the group of people living together, as for those we interviewed during the user requirement collection, a common planning can be done by the whole group with the help of the caregivers. The single activities will then be assigned to specific people who will be in charge of doing them and they will automatically fill up their personal agenda.  
A centralized cloud based system stores all the users' data and all the information on the use of the system for later use.
