**4. Service framework and evaluation methods**

Digital amenities would provide services that would enhance life values for citizens. These services are gathered, organized in a scenario format, and evaluated through ICT for everyday life, types of a spatial model, and content factors described previously.

The values for citizens can be divided into technological values and psychological values as shown in figure 3. The technological values can be measured by the speed and efficiency of service delivery with the amount of cost and energy. The psychological values ascribe feelings of safety, security, and happiness.

To model a smart city with digital amenities, not only are physical spaces required to be based on ICT environments, but they are also required to be incorporated into a conventional internet based data community, say virtual space shown in figure 4. The networking of scattered spaces is also required to uplift life values in terms of content storage and distribution.

Based on the analysis of four urban space types, civil services are studied and organized in a series of events and respective actions. Four factors of figure 2 have been the starting point to conceptualize the digital amenity that provides citizens designed services in a smart city.

By analyzing the unit service models defined from the ubiquitous city research, the services that satisfy the needs of a target city are derived, in which they are evaluated and articulated for further implementation of a platform and rule engine. For the evaluation of services, the QFD(Quality Function Deployment) and SVD(Service Value Deployment) methods (figure 5) are utilized in order to prioritize the services based on space classes, customer requirements and technology properties.
