Abstract
Situation analytics can be used to recognize the changing behavior, emotional state, cognitive load and environmental context of a user during complex task processing. This article discusses the SitAdapt 2.0 architecture that combines a situation analytics platform with pattern- and model-based user interface construction tools in order to build runtime-adaptive interactive business applications with enhanced user experience and task-accomplishment characteristics. The article focuses on the software components and tools for observing and tracking the user, data types for modeling situations, recognizing situations, and modeling structural changes and actions for generating the dynamic adaptations. The situation recognition capabilities and adaptive functionality of the system are demonstrated for web-applications for long-distance travel booking and a beauty products web-portal.
Highlights
Situation- and context-aware computing has an established tradition in the area of distributed mobile computing [1] and complex interactive systems [2]
The evaluation and decision component uses the data that are provided by the situation analytics component to decide whether an adaptation of the user interface is currently meaningful and necessary
Goals to meet can range from successful marketing activities in e-business, e.g. having the user buying an item from the e-shop or letting her or him browse through the latest special offers, to improved user experience levels, or to meeting user desires defined by the hidden mental states of the user
Summary
Situation- and context-aware computing has an established tradition in the area of distributed mobile computing [1] and complex interactive systems [2]. The availability of easy-to-use softand hardware tools for gathering visual or bio-physical user data and for observing user interactions and tracking activities has created the desire to systematically exploit the collected data for engineering dynamically adaptive software systems.
