Despite a few authors recently used or studied visual complexity, the concept of visual complexity still needs to be better defined for the use in HCI research and GUI design, with its underlying aspects systematized and operationalized, and different measures validated. This paper reviews the aspects of GUI visual complexity and operationalizes four aspects with nine computation-based measures in total. Two user studies validated the measures on two types of stimuli - webpages (study 1, n = 55) and book pages (study 2, n = 150) - with two user groups, dyslexics (people with reading difficulties) and typical readers. The same complexity aspects could be expected to determine complexity perception for both GUI types, whereas different complexity aspects could be expected to determine complexity perception for dyslexics, relative to typical readers. However, the studies showed little to no difference between dyslexics and average readers, whereas web pages did differ from book pages in what aspects made them seem complex. It was not the intergroup differences, but the stimulus type that defined criteria to judge visual complexity. Future research and visual design could rely on the visual complexity aspects outlined in this paper.","PeriodicalId":330748,"journal":{"name":"Proceedings of the 2018 International Conference on Advanced Visual Interfaces","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127365895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using the body as a support to combine both dimensions has therefore been proposed, but no formal evaluations have yet been reported. In this paper, we compare an on-body interaction technique (BodyLoci) to mid-air Marking menus in a virtual reality context. We consider three levels of semantic aids: no aid, story-making, and story-making with background images. Our results show important improvement when story-making is used, especially for Marking menus (28.5% better retention). Both techniques performed similarly without semantic aids, but Marking menus outperformed BodyLoci when using them (17.3% better retention). While our study does not show a benefit in using body support, it suggests that inducing users to leverage simple learning techniques, such as story-making, can substantially improve recall, and thus make it easier to master gestural techniques. We also analyze the strategies used by the participants for creating mnemonics to provide guidelines for future work.","PeriodicalId":330748,"journal":{"name":"Proceedings of the 2018 International Conference on Advanced Visual Interfaces","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126087875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the class game, stretches of distance travelled in a sustainable way by each child contributes to the advancement of the whole school on a collective virtual trip. During the trip, several virtual stops are associated with the discovery of playful learning material. The approach has been evaluated in a primary school with 87 pupils and 6 teachers actively involved in the learning activity for 12 continuous weeks. The findings from the questionnaires with parents and the interviews with teachers show a positive effect in terms of children's behavioural change as well as educational value. Indications on the use of class and school collaborative gamification activities for supporting sustainable behavioural change are discussed.","PeriodicalId":330748,"journal":{"name":"Proceedings of the 2018 International Conference on Advanced Visual Interfaces","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129835423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Domestic environments can include furniture and other obstacles that hinder the ease with which users can naturally walk. By leveraging the benefits of passive haptics, users can match physical objects with virtual counterparts, to create substitutional environments. In this paper we explore two visualisation modalities to aid in the creation of a coarse virtual representation of the physical environment, by marking out the volumes of space where physical obstacles are located, to support the substitution process. Our study investigates whether this process is better supported by an inside-looking-out 3D User Interface (that is, viewing the outside world while immersed in Virtual Reality) or from an outside-looking-in one (while viewing the Virtual Environment through an external device, such as a tablet). Results show that the immersive option resulted in better accuracy and was the one with the highest overall preference ratings.","PeriodicalId":330748,"journal":{"name":"Proceedings of the 2018 International Conference on Advanced Visual Interfaces","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121743827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Focusing on the user authentication domain, graphical passwords are considered a better fit for interaction environments which lack a physical keyboard. Nonetheless, the current graphical user authentication schemes are deployed in conventional layouts, which introduce security vulnerabilities associated with the strength of the user selected passwords. Aiming to investigate the effectiveness of advanced visualization layouts in selecting stronger passwords, this paper reports a between-subject study, comparing two different design layouts a two-dimensional and a three dimensional. Results provide evidence that advanced visualization techniques provide a more suitable framework for deploying graphical user authentication schemes and underpin the need for considering such techniques for providing assistive and/or adaptive mechanisms to users aiming to assist them to create stronger graphical passwords.","PeriodicalId":330748,"journal":{"name":"Proceedings of the 2018 International Conference on Advanced Visual Interfaces","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114585667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present a demo showing how a platform supporting End User Development (EUD) of context-dependent applications has been customized for remotely assisting elderly people at home. The user-editable personalisation features are specified by using trigger-action rules. The platform has been integrated with various sensors and appliances, and an application for remotely monitoring older adults at home. The resulting environment supports the possibility of creating trigger-action rules that can actually be executed when relevant sensors indicate that specific events or conditions occurred.","PeriodicalId":330748,"journal":{"name":"Proceedings of the 2018 International Conference on Advanced Visual Interfaces","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124774726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this approach only supports pixel height manipulation and cannot produce more radical shape changes of each pixel (and thus of the display). Examples of such changes include non-horizontal pixels, pixels that overhang other pixels, or variable gaps between pixels. We present a concept for composing shape-changing interfaces by vertically stacking tilt-enabled modules. Together, stacking and tilting allow us to create a more diverse range of display surfaces than using arrays. We demonstrate this concept through TiltStacks, a shape-changing prototype built using stacked linear actuators and displays. Each tiltable module provides three degrees of freedom (z-movement, roll, and pitch); two more degrees of freedom are added through stacking modules (i.e., planar x- and y-movement).","PeriodicalId":330748,"journal":{"name":"Proceedings of the 2018 International Conference on Advanced Visual Interfaces","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121396602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using active visual stimuli, such as animated or flashing objects, is effective for gaze guidance; however, it has been reported that such an approach often results in unpleasant feelings for users. This paper proposed a new method for gaze guidance using artificial color shifts that does not induce unpleasant feelings in the user. We created an image filter that separates the image in three layers, i.e., cyan, magenta, and yellow, and slightly shifted each layer the left, right, and down, respectively. The filter was applied to the entire image except the region where the user's gaze was to be guided. We conducted experiments using a gaze tracker. The experimental results showed that the proposed method can guide the user's gaze to a particular region with less unpleasant feelings.","PeriodicalId":330748,"journal":{"name":"Proceedings of the 2018 International Conference on Advanced Visual Interfaces","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122251847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

HiMVis visualizes packages and class hierarchies through two space-filling interactive layouts. Further, it shows on demand through multiple views more than fifty software metrics information associated to a particular class or interface over all development releases.
