A Study On User Requirements And Innovative Features Of Location Based Services

The coming of 3rd Generation provides a broader development space for mobile value-added services.With mobility,usability,at any time and personalized features, location based services(LBS) is to become one of the most potential mobile value-added services.This thesis is a part of the project commissioned by one of the native communication technologies companies,and aims to study the user experience and user requirements about LBS in China.And then create innovative features to meet user requirements.This research include literature investigation,definition of user groups,collection of use context data,the use context data analysis,user requirements extraction, innovative features creation and prototype design.In the phase of literature investigation, the current status of LBS development and user research is summarized based on extensive collection of location based services information.Combining the results of investigation,relevant market research reports and our previous experience of the user study,we identified the target user group.On the basis of the definition of user groups, conditions selecting user are established in the stage of use context data collcetion.And 20 users in Dalian and Shanghai are chosen.After collect 20 users' data with semi-structured interview and contextual inquire.Behavior variables analysis is conducted to analyse use context data.And then based on the results of the analysis 5 personas and some context scenarios corresponding to each persona are established. After analysing personas and scenarios with brainstorming,potential user requirements are extraceted and classified.Finally,according to the analysis of requirements,as well as system development professionals' advice,10 innovative features are identified. Then the interaction prototype including the 10 innovative features is designed in order to provide basis for the stage of user confirmation.In the whole progress of the research,the theory of user centered design is implemented strictly.The research extracting the potential user requirements,creating corresponding innovative features,lays foundation for in-depth researches and has reference significance for the application of UCD theory and methods in the mobile interaction domain.
