Optimizing Heuristic Evaluation Process in E-Commerce: Use of the Taguchi Method

This article proposes a 3-dimensional (3D) vision-based ambient user interface as an interaction metaphor that exploits a user's personal space and its dynamic gestures. In human-computer interaction, to provide natural interactions with a system, a user interface should not be a bulky or complicated device. In this regard, the proposed ambient user interface utilizes an invisible personal space to remove cumbersome devices where the invisible personal space is virtually augmented through exploiting 3D vision techniques. For natural interactions with the user's dynamic gestures, the user of interest is extracted from the image sequences by the proposed user segmentation method. This method can retrieve 3D information from the segmented user image through 3D vision techniques and a multiview camera. With the retrieved 3D information of the user, a set of 3D boxes (SpaceSensor) can be constructed and augmented around the user; then the user can interact with the system by touching the augmented SpaceSensor. In the user's dynamic gesture tracking, the computational complexity of SpaceSensor is relatively lower than that of conventional 2-dimensional vision-based gesture tracking techniques, because the touched positions of SpaceSensor are tracked. According to the experimental results, the proposed ambient user interface can be applied to various systems that require real-time user's dynamic gestures for their interactions both in real and virtual environments.     

Facets of simplicity for the smartphone interface: A structural model

Motivated by the need to develop an integrated measure of simplicity perception for a smartphone user interface, our research incorporated visual aesthetics, information design, and task complexity into an extended construct of simplicity. Drawn from three distinct domains of human–computer interaction design and related areas, the new development of a simplicity construct and measurement scales were then validated. The final measurement model consisted of six components: reduction, organization, component complexity, coordinative complexity, dynamic complexity, and visual aesthetics. The following phase aimed at verifying the relationship between simplicity perception of the interface and evaluations of user satisfaction. The hypothesis was accepted that user satisfaction was positively affected by simplicity perception and that the relationship between the two constructs was very strong. The findings imply that a simplified interface design of the task performance, information hierarchy, and visual display attributes contributes to positive satisfaction evaluations when users interact with their smartphone as they engage in communication, information search, and entertainment activities.

Structural approach to design user interface

The analysis of the interactive relations among interface elements using a structuralized method can help user interface designers to satisfy the different requirements of design and improve design efficiency. This study develops a three-stage structured user interface design approach for complex information systems consisting of multiple components. First, the Quality Function Development (QFD) approach is used to confirm the user's design demand and its mapping components. Next, the Interpretive Structural Model (ISM) technique is adopted to construct a clear model of a hierarchical structure. Finally, the Impact Matrix Cross-Reference Multiplication Applied to a Classification (MICMAC) approach is employed to analyze the effect and dependence among the overall design components, and to consider the relationship network graph of distribution of components in the system. The research approach applies the Web mail system as its case study. Through the empirical study of web-based system, interface designers can effectively grasp a user's differentiated demand that changes rapidly and reflect it in the combination of designed components. This study establishes a strategy for creating an information system design pattern with multiple components is by building a hierarchical structure and analyzing the component distribution.     

Bridging the Information Transfer Gap: Measuring Goodness of Information Fit

The ability to determine, a priori, how well an interface design meets the information needs of a user—that is, to ‘bridge the information transfer gap’—is a critical component of any intelligent interface design system. Yet most current approaches either sidestep the problem of computationally measuring ‘goodness of fit’ by compiling design knowledge into a set of pattern matching rules or, at best, use a very limited set of parameters in scoring. We describe a formal representation for capturing the information needs associated with user tasks and the information conveying capabilities of interface elements. A multifaceted scoring technique, using this representation, is presented for assessing a design's goodness of fit against current user requirements. The hallmarks of this approach are the explicit representation of the goals of good user interface design, evaluation of a proposed design against these goals and a computational approach to performing tradeoffs among these goals when incompatible. Finally, we report on the implementation and user acceptance of this design in an adaptive interface application for military attack/scout helicopters.     

Predicting program execution times by analyzing static and dynamic program paths

This paper describes a method to predict guaranteed and tight deterministic execution time bounds of a sequential program. The basic prediction technique is a static analysis based on simple timing schema for source-level language constructs, which gives accurate predictions in many cases. Using powerful user-provided information, dynamic path analysis refines looser predictions by eliminating infeasible paths and decomposing the possible execution behaviors in a pathwise manner. Overall prediction cost is scalable with respect to desired precision, controlling the amount of information provided. We introduce a formal path model for dynamic path analysis, where user execution information is represented by a set of program paths. With a well-defined practical high-level interface language, user information can be used in an easy and efficient way. We also introduce a method to verify given user information with known program verification techniques. Initial experiments with a timing tool show that safe and tight predictions are possible for a wide range of programs. The tool can also provide predictions for interesting subsets of program executions.This research was supported in part by the Office of Naval Research under grant number N00014-89-J-1040.
