“…It indicates that grouping of icons occurred and that it facilitated a more efficient search. Also, the findings are in line with previous research showing the influence of color when highlighting important aspects of computer pictograms (Bzostek & Wogalter, 1999 ; McDougald & Wogalter, 2014 ) or showing the impact of icon grouping (Brumby & Zhuang, 2015 ; Niemelä & Saarinen, 2000 ).…”

“…In this context, negative consequences of similarity grouping should be examined in greater detail. McDougald and Wogalter ( 2014 ) have already reported a disadvantage when irrelevant areas are highlighted by colors. Likewise, an uncontrolled similarity of colored app icons (e.g.…”

“…through well-defined perceptual groups) also enable a fluent search (see, for example, Scott, 1993 for a detailed review) under more realistic search environments using app icons as search elements. McDougald and Wogalter ( 2014 ) focused on the influence of color to guide the user’s attention. They reported more correct descriptions of pictograms if relevant areas of the pictograms were highlighted by color than if there were no highlighting.…”

App icon similarity and its impact on visual search efficiency on mobile touch devices

Users of mobile touch devices are often confronted with a great number of apps, challenging an efficient access to single applications. Especially when looking for infrequently used apps, users have to perform a visual search. We address this problem in two studies by applying knowledge about visual search efficiency to app icons on mobile touch devices. We aimed to transfer findings of similarity grouping for complex stimuli to a more applied setting and to investigate the effect of search efficiency on user experience. In Study 1 (N = 18), we varied set size and target presence as well as visual similarity between icons by color manipulation. Results indicated a highly efficient search when the target was easy to discriminate from the distractors and a less efficient search with increasing similarity. These results were replicated in a second, more realistic use case (N = 36). Regarding user experience, Study 2 showed that perceived usability and intuitiveness increased with search efficiency but that the overall liking also depended on the visual variety of the design. Moreover, although participants showed a general interest in a system supporting their search, most participants had concerns about data privacy with such a system. In conclusion, the results indicate that concepts and findings from basic attention research serve as fruitful heuristics for searches in more realistic (applied) settings. Furthermore, results showed that similarity manipulation with color works without controlling for other icon characteristics (e.g. luminance, shade). The findings might offer a new approach when designing for smooth interaction with mobile touch devices.

“…The issue related to pictorials’ features and their role in safety signs’ comprehension in different cultures should be further investigated, by identifying the most critical details for different cultures and by testing the efficacy of some redesigned solutions to enhance pictorials’ comprehension, as suggested by many authors [55,56]. For instance, considering the complex relationship between human figures and tools and machinery, it could be useful to: (i) reduce the number of additional details that could cause misunderstanding; (ii) depict the different parts of the whole pictorial improving the balance between solid shapes and outline shapes to make each part more comprehensible; and (iii) reduce the abstractness of the action, depicting the specific action.…”

The comprehension of safety signs affixed to agricultural machinery is fundamental to warning users about the residual risks which cannot be eliminated with machinery design and the adoption of protections. This is particularly relevant for the migrant workforce, which may encounter some language barriers with written safety communication. The present study aimed to investigate the comprehension of safety signs affixed to agricultural machinery in a group of migrants from both European and non-European countries employed in Italian agriculture. Thirty-seven migrant farmworkers (12 Indians, 17 Pakistanis, and eight Romanians) were individually interviewed to test the comprehension of four safety signs referring to the main causes of fatal and non-fatal injuries caused by interactions with farm machinery. Romanians obtained the highest comprehension performance (68.8% of correct answers), followed by Indians (35.4%), with Pakistanis being last (32.4%). The nationality and the previous experience as a farmworker significantly affected the comprehension of safety signs. The results pointed out the importance of adequately training migrants on the meaning of safety signs. Beside this, the study suggests a redesign of the signs, considering some signs’ features to enhance pictorials’ cross-cultural comprehension.
