Abstract
Context-aware user interface plays an important role in many human-computer Interaction tasks of location based services. Although spatial models for context-aware systems have been studied extensively, how to locate specific spatial information for users is still not well resolved, which is important in the mobile environment where location based services users are impeded by device limitations. Better context-aware human-computer interaction models of mobile location based services are needed not just to predict performance outcomes, such as whether people will be able to find the information needed to complete a human-computer interaction task, but to understand human processes that interact in spatial query, which will in turn inform the detailed design of better user interfaces in mobile location based services. In this study, a context-aware adaptive model for mobile location based services interface is proposed, which contains three major sections: purpose, adjustment, and adaptation. Based on this model we try to describe the process of user operation and interface adaptation clearly through the dynamic interaction between users and the interface. Then we show how the model applies users' demands in a complicated environment and suggested the feasibility by the experimental results.
Highlights
USA Scholar Schlit first proposed three target location based services (LBS) in 1994: spatial information, social information, and resources nearby
Context-aware human-computer interface makes mobile LBS interaction more natural and efficient which is able to adapt to different users’ characters and requirements by taking advantage of usable information about users’ tasks. Many of these adaptive interfaces serve specific users, such as the interface which Cao designed for children that apply cartoon-icon in 2007 [1] and the user interface adaptation proposed by Zouhaier et al which is based on context awareness for disabled people in 2013 [2], for the characters of specific users are obvious
Adaptive user interface model consists of the following components: user model (UM), task model (TM), interaction model (IM), domain model (DM), environment model (EM), and presentation model (PM)
Summary
USA Scholar Schlit first proposed three target location based services (LBS) in 1994: spatial information, social information, and resources nearby. Context-aware human-computer interface makes mobile LBS interaction more natural and efficient which is able to adapt to different users’ characters and requirements by taking advantage of usable information about users’ tasks (e.g., locations and preferences of users, experiences, and surrounding environments). Many of these adaptive interfaces serve specific users, such as the interface which Cao designed for children that apply cartoon-icon in 2007 [1] and the user interface adaptation proposed by Zouhaier et al which is based on context awareness for disabled people in 2013 [2], for the characters of specific users are obvious. In the following Related Works section the feasibility and applicability of contextaware interface to be adapted to users in some solutions are discussed
