Selection Tasks

The purpose of the present study was to compare user performance, accuracy and preference while using standard user interface controls or “widgets” to complete specific types of tasks. Radio buttons were significantly faster, accurate, and preferred than any outer widget for the mutually exclusive selection tasks. For the non-mutually exclusive selection tasks, check boxes were significantly faster and preferred. These widgets were superior due to the fact that all possible options were initially visible. As the number of options increased, the time to complete each task also increased. A practitioner's table for selecting effective widgets for specific types of tasks is provided. Further implications for user interface design and research are discussed.

The Web

Collaborative media are the most rapidly expanding form of communication in the business and user domains. Channels such as blogs, social networks, and file sharing sites present exciting opportunities for satisfying consumers' needs for information, entertainment, and commerce. The objective of this research was to determine the effects of interface design and context of use on performance and preference with the most common collaborative media channel, the web log. Design manipulations modified the amount of information presented on each page in two orthogonal ways to vary the amount of navigation required to access desired content. Contextual manipulations modified the subject domain of the content, the specificity of the tasks that users were assigned, and the time pressure placed on the user to browse the content. The effects of these manipulations were assessed by measuring the time users spent navigating the site and several measures of performance in an immediate recall test. All of the manipulations affected user performance in a variety of ways. Insights for the design of collaborative media are provided.

Grip posture needs to be considered to ergonomic smartphone interface design for better usability in terms of controllability, user performance, and stability. The present study is intended to objectively classify grip postures of smartphone when users conduct tasks with hard keys. Forty five smartphone users conducted tasks with nine smartphone mock-ups in different sizes. Two cameras were located above and under a smartphone mock-up and recorded synchronized videos of grip postures. The grip postures of smartphone were classified by counting the number of fingers at each side of smartphone. Three dominant grip postures of smartphone were identified in the experiment: (1) 3-finger left, 1-finger right, and 1-finger back support (70.0%), (2) 4-finger left and 1-finger right (13.3%), and (3) 3-finger left, 1-finger right, and 1-finger top (12.0%). Device size, hand width, and hand length were found significantly influential to grip posture. The grip postures identified in the present study would be of use in ergonomic smartphone interface design.

A challenge in presenting augmenting information in outdoor augmented reality (AR) settings lies in the broad range of uncontrollable environmental conditions that may be present, specifically large-scale fluctuations in natural lighting and wide variations in likely backgrounds or objects in the scene. In this paper, we motivate the need for research on the effects of text drawing styles, outdoor background textures, and natural lighting on user performance in outdoor AR. We present a pilot study and a follow-on user-based study that examined the effects on user performance of outdoor background textures, changing outdoor illuminance values, and text drawing styles in a text identification task using an optical, see-through AR system. We report significant effects for all these variables, and discuss user interface design guidelines and ideas for future work.
