“…From the review of the literature it was found in Huang and Lai's (2008) paper that icons are typically less than 64 £ 64 pixels. To examine the effect that target size has on the user's ability to select an object, the second task was designed with objects of different sizes, distances from other objects and different layouts of objects.…”

AbstractPurpose -This paper is about an investigation into the usability of touch-based user interfaces. Currently, not enough knowledge is available to guide user interface designers and developers concerning the appropriate use of touch-based technology. The paper aims to discuss these issues. Design/methodology/approach -The authors adopt an empirical approach using an experiment to test the effectiveness and user satisfaction of touch-based interaction compared with equivalent mouse-based interaction. The authors had two abstract type tasks and one contextualised task using the two methods of interaction. The authors measured errors, task time and user satisfaction. Findings -The data were statistically analysed and the statistically significant results show that overall the mouse-based interaction was faster, caused fewer errors and was preferred by the participants. Originality/value -These results are interesting for all user interface designers and developers, where the authors make some design suggestions based on the empirical results. The results also add to the current knowledge the authors have regarding interaction with touch interfaces. Further, the authors also propose ways forward to enrich this research area of further knowledge.

“…The popularization of the Internet has driven the development of mobile devices and especially the increasing use of touch-based mobile phones and tablets [24], making communication through interfaces an integral part of daily life [18,25]. Other than the number, size [26], and position of buttons, the touch area is the most important factor affecting the operation of touch screens [27]. In past studies, users have expressed concern regarding the touch area of the screen, as the size of the touch area affects performance and operation [28,29].…”

The Influence of the Interface Button Design of Touch Screens on Operation and Interpretation by Elderly and Middle-Aged Adults

Body function begins to decline in middle age, with changes becoming increasingly noticeable over time. With the popularization of educational and information technology, people know more about healthcare and are becoming accustomed to self-testing using health equipment. Technological changes are reflected in products, which present innovations including the switch from traditional to touch-controlled interface designs. This can cause difficulties in the interpretation and interface operation for older adults, who may be facing physiological and psychological alterations. Understanding users’ physiological limitations has become an important aspect of product design. This study explored the effects of physiological limitations on touch-screen operation in middle-aged and elderly people, specifically regarding button type, display position, and button size. A total of 64 participants were included in the study: 32 middle-aged people (aged 45–64 years) and 32 elderly people (65 years of age and older). Each participant was asked to complete 32 tasks (two button categories × four button sizes × four presentation positions). The results revealed no differences between the elderly and the middle-aged groups with regard to the interpretation of image buttons and text buttons; however, button size affected the operation and interpretation time. Middle-aged participants demonstrated good interpretation performance when the buttons were displayed in the upper or lower part of the screen, whereas elderly participants only had a good interpretation performance when the buttons were in the upper part. For both groups, the ideal image button size was 16 mm with a text font size of 22.

“…Today, icons are everywhere on computers, mobile phones and tablets, but paradoxically, less attention is paid to the formalization of their semantics. Recent works focus on graphical design [16] and usability evaluation [17], rather than on the semantics itself. In the medical field, two examples of such works involve the icon design for a user interface of remote patient monitoring mobile devices [18], and for creating icons for an emergency medical information system, using participatory design [19].…”

International audienceIconic languages can represent concepts by the combination of graphical components (such as colors or pictograms). There are numerous examples, from traffic signs to computer user interface icons. However, these languages do not associate formalized semantics to their icons, which raises various problems: inconsistent combinations of graphical components, different interpretations of a given icon by two persons, difficulties to map the icons to the concepts of existing termino-ontological resources, etc. In this article, we describe a method that formalizes the semantics of an iconic language with an ontology. This method was initially developed for the VCM iconic language (Visualization of Concepts in Medicine), which enables to represent the main medical concepts (antecedents, disorders, treatments, etc.) by icons. We show that it can be generalized to other iconic languages, including traffic signs. We also describe four practical applications made possible by the formalization of the language semantics: the verification of icons consistency, the semi-automatic alignment with terminologies, the automatic generation of a pictogram lexicon and the automatic generation of icon labels. The article also presents the VCM ontology, the implementation details of a semantic iconic server with fast response times, and the evaluation results obtained when evaluating the four applications
