On today's graphical user interface(GUI), users often implicitly perform various trajectory-based interactions, such as navigating through menus [2], entering the boundary of a button,

Database query is becoming a common task in public access systems; touchscreens can provide an appealing interface for such a system. This paper explores three interfaces for constructing queries on alphabetic field values with a touchscreen interface; including a QWERTY keyboard, an Alphabetic keyboard, and a Reduced Input Data Entry (RIDE) interface. The RIDE interface allows field values to be entered with fewer “keystrokes” (touches) than either keyboard while eliminating certain errors. In one test database, the RIDE interface required 69% fewer keystrokes than either keyboard interface.
Toolglass [Bier et al. 1993] demonstrated a two-handed command selection technique that combined command selection and direct manipulation. While empirical evaluations showed a speed advantage for ToolGlass, they did ...

Several steps that need to be followed to ensure better reporting and tracking of medical errors are presented. One of steps is to use improved electronic health records (EHR) user-interface designs that offer healthcare providers shorter learn-times, faster performance, and lower interface error rates. A second step should be agreements on user interface consistency and data interoperability among the 100-plus developers of EHR. Such guidelines for consistency and data sharing, common in other industries, would allow healthcare professionals who work at more than one location to do their jobs more efficiently and safely. Guidelines for user interfaces and public reporting of usability testing for errors would lay the foundation for changes in the way data is handled. The independent oversight panels, convened by healthcare providers, professional organizations, and government agencies, would specify improvements in information technologies and processes for software developers, hospitals, and labs.

After an historical review of evaluation methods, we describe an emerging research method called Multi-dimensional In-depth Long-term Case studies (MILCs) which seems well adapted to study the creative activities that users of information visualization systems engage in. We propose that the efficacy of tools can be assessed by documenting 1) usage (observations, interviews, surveys, logging etc.) and 2) expert users' success in achieving their professional goals. We summarize lessons from related ethnography methods used in HCI and provide guidelines for conducting MILCs for information visualization. We suggest ways to refine the methods for MILCs in modest sized projects and then envision ambitious projects with 3-10 researchers working over 1-3 years to understand individual and organizational use of information visualization by domain experts working at the frontiers of knowledge in their fields.
