This paper describes the evaluation of a gesture-based mechanism for issuing the back and forward commands in web navigation. Results show that subjects were able to navigate significantly faster when using gestures compared to the normal back button. They were also extremely enthusiastic about the technique, with several expressing their wish that "all browsers should support this".

Identification of patterns in time series data sets is a task that arises in a wide variety of application domains. This paper presents a user interface for the timebox query model of rectangular regions that specify constraints over time series data sets. A prototype application based on timeboxes is presented. Collaborations with potential users will guide the design of enhanced functionality. Usability tests and controlled experiments will be conducted to evaluate the timebox query model.

A dynamic query interface for finding patterns in time series data is demonstrated. The identification of patterns in time series data sets is a task that arises in a wide variety of application domains. It is reported that this demonstration presents the timebox model of rectangular regions that specify constraints for dynamic queries over time series data sets, and the TimeSearcher application, which uses timeboxes as the basis of an interactive query tool.

The tutorial begins with a model of creative processes and refines it into design principles. Participants will learn of eight ways to improve software that supports human creative processes: searching and browsing digital libraries, visualizing data and processes, consulting with peers and mentors, thinking by free associations, exploring solutions: what-if tools, composing artifacts and performances, reviewing and replaying session histories, and disseminating results. These practical suggestions can be integrated into existing software applications, built into web services, or serve as the framework for novel tools. Software examples will be shown and brainstorming sessions will use projects from participants.

The analysis of multidimensional functions is important in many engineering disciplines, and poses a major problem as the number of dimensions increases. Previous visualization approaches focus on representing three or fewer dimensions at a time. This paper presents a new focus+context visualization that provides an integrated overview of an entire multidimensional function space, with uniform treatment of all dimensions. The overview is displayed with respect to a user-controlled polar focal point in the function's parameter space. Function value patterns are viewed along rays that emanate from the focal point in alt directions in the parameter space, and represented radially around the focal point in the visualization. Data near the focal point receives proportionally more screen space than distant data. This approach scales smoothly from two dimensions to 10-20, with a 1000 pixel range on each dimension.

HANDS is a new programming system for children that was designed for usability. This paper examines the effectiveness of three features of HANDS: queries, aggregate operations, and data visibility. The system is compared with a limited version that lacks these features. In the limited version, programmers can achieve the same results but must use more traditional programming techniques. Children using the full-featured HANDS system performed significantly better than their peers who used the limited version. This provides evidence that usability of programming systems can be improved by including these features.

The rapid growth of Short Message Service (SMS) text messaging is generating substantial commercial and research interest in fast and efficient text input methods for mobile devices. This paper presents an empirical study that compares three mobile phone text input techniques. The methods are 'multi-press input with timeout', 'multi-press input with a next button', and 'two-key'. The study shows that there is a significant speed difference, in words per minute (wpm), between the methods. The multi-press with next method provided the most rapid text input at 7.2 wpm, followed by multi-press with timeout at 6.4 wpm. The two-key method was the slowest at 5.5 wpm. These results are much slower than those predicted by Fitts' Law models reported in prior research. Subjective results regarding learnability, errors and efficiency showed no significant difference between the methods.
