User Actions

Human factors engineering research into human-computer interaction (HCI) needs means to easily and objectively study HCI. The Instrumented Interface Construction (IICON) Evaluator, and its associated IICON Data Taps, provide such means. Any X Window system user interface built using development tools for which appropriate IICON Data Taps exist (e.g., IICON Data Taps/TAE+5.2) can be automatically instrumented. Instrumented interfaces can then be used by subjects, recording a complete transcript of user actions. Once an operator's session has been recorded, it can be replayed on-screen as needed for further observation and analysis. These capabilities are extremely helpful for developing cognitive task models (i.e., user models) for analytic purposes, or for construction of Intelligent Agents to be embedded in the operator's computer-based workstation. Furthermore, with a complete objective record of all operator actions, IICON Evaluator supports a wide variety of research investigations of HCI.

The Way

In this article, we present MyrrorBot , a personal digital assistant implementing a natural language interface that allows the users to: (i) access online services, such as music, video, news, and food recommendation s, in a personalized way, by exploiting a strategy for implicit user modeling called holistic user profiling ; (ii) query their own user models, to inspect the features encoded in their profiles and to increase their awareness of the personalization process. Basically, the system allows the users to formulate natural language requests related to their information needs. Such needs are roughly classified in two groups: quantified self-related needs (e.g., Did I sleep enough? Am I extrovert? ) and personalized access to online services (e.g., Play a song I like ). The intent recognition strategy implemented in the platform automatically identifies the intent expressed by the user and forwards the request to specific services and modules that generate an appropriate answer that fulfills the query. In the experimental evaluation, we evaluated both qualitative (users’ acceptance of the system, usability) as well as quantitative (time required to complete basic tasks, effectiveness of the personalization strategy) aspects of the system, and the results showed that MyrrorBot can improve the way people access online services and applications. This leads to a more effective interaction and paves the way for further development of our system.
