Greater understanding of the grip postures preferred by users is needed for the ergonomic design of smartphone user interfaces. The present study identifies user-preferred grip postures by smartphone size and hand size in one-handed hard key operations. Grip postures of 45 participants were photographed while major smartphone tasks were simulated in standing with smartphone mockups of nine screen sizes (3.0″–7.0″). The grip postures were encoded by the locations (left side: L, right side: R, top: T, bottom: B, front: F, back: K) of a smartphone and the number of fingers at each contact location. Three grip postures (L3-R1-K1: 70.0%, L4-R1: 13.3%, L3-R1-T1: 12.0%) were found dominant and the distribution of grip posture changed by smartphone size and hand size—the larger the smartphone size or hand size, the higher the frequency of L3-R1-K1. The grip posture frequency distribution by smartphone size would be of use to determine the optimal locations of hard keys on a smartphone of a particular size.

Significant Effort

Problems attributed to uncertainty and a lack of visibility about others’ activities and behaviors have led designers of multi-user interfaces to develop so-called awareness mechanisms (Dourish & Bellotti, 1992). The importance of maintaining awareness in the virtual environment has been outlined in many studies in CSCW and Human-Computer Interaction (HCI) research areas. According to Gutwin, Greenberg and Roseman (1996), awareness reduces the effort needed to coordinate tasks and resources by providing a context in which to interpret utterances and to anticipate others’ actions. For many years, a significant effort was devoted to explore how computer-based technologies might facilitate some kinds of awareness among and between interdependent actors. These studies tried to solve technical problems related to providing awareness through multi-user interfaces. Unfortunately, however, the expected benefits from these technologies never materialized (Schmidt, 2002). This article focuses on the design of visualization techniques for collective awareness. It proposes a design approach of visualization techniques centered on the semantic of collective awareness and human characteristics (ergonomic design). The article is organized as follows: First, we present users’ needs when interacting through multi-user interfaces. Second, we give an overview of the notion of awareness by reviewing its categories. Third, we present an ergonomic design approach of awareness visualization techniques. We illustrate our approach with examples of techniques from literature and show how these techniques support collective awareness. Finally, we conclude with some future directions.

Communication Modalities

We are living in a post-WIMP world. Indeed, more and more users access information, communicate and operate mobile information appliances foregoing the still common mouse and keyboard of yonder. However, no matter how powerful or elegant the new mobile devices are, it is the user interface that ultimately governs how successful new devices or systems will be. In this lecture I will look at current multimedia systems and their applications to virtual environments and ubiquitous computing. Multimedia user interfaces currently engage people using images, video and sound but virtual environments not only involve interactive 3D graphics, but further need to take more advantage of our senses through spatial audio, haptics and many other novel and exciting communication modalities. This talk will explore key current research issues and future directions up to and before the prophesized singularity.
