However, our study of this interface revealed that concealing the impact of network context on the security state of the firewall results in mental models that are unclear about the protection provided by the firewall resulting in an inaccurate understanding of the firewall configuration. We developed a prototype to support more contextually complete mental models through inclusion of network context information. Results from our initial evaluation of the prototype support our approach of improving user understanding of underlying system states by revealing hidden context, while considering the tension between complexity of the interface and security of the system.","PeriodicalId":402696,"journal":{"name":"CHI '09 Extended Abstracts on Human Factors in Computing Systems","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129992393","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}

Increasingly, Web services are developed for both PCs and mobile terminals to support user needs for media content management and social interaction. Even though many UX models have been developed over the last decade, the specific characteristics affecting UX of Web services have not been studied systematically. In this paper we present the first phase of our service UX study in which three Web services were evaluated by three UX experts each, using an initial set of service UX evaluation heuristics. We discuss how well these heuristics covered the positive and negative service UX evaluation findings, and how the heuristics and the expert evaluation approach of UX should be developed further.","PeriodicalId":402696,"journal":{"name":"CHI '09 Extended Abstracts on Human Factors in Computing Systems","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130010800","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}

As the capacities of our digital tools have grown, they have begun to make readily available to us unprecedented quantities of new, rich, structured temporal information about the people and things in our lives. This abundance of information has laid open avenues for new tools and applications - applications which, in turn, introduce new demands on interface mechanisms used to display, represent and interact with temporal data. This workshop, the second in a series on Capturing, Interacting with and Visualizing Temporal Data, will focus on such demands, examining interaction challenges emerging across new application domains.","PeriodicalId":402696,"journal":{"name":"CHI '09 Extended Abstracts on Human Factors in Computing Systems","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134599637","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}

A popular way to help users organize their information is tagging, as is the case in web sites such as flickr, delicious or youtube. Unlike traditional hierarchically-based organization principles, tagging is less strict and easier to employ. However, it is not without its own problems. Low tag reuse is just one of several issues that might hinder retrieval of a document or photo at a later time. We propose that narratives can provide a better way of tagging photos. Describing a photo by telling a story about it may yield more and better tags, as information in stories is organized as a structured, coherent whole. We present a prototype web application, StoryTags, that allows users to tell stories to tag their photos, and then to use those stories to retrieve them.","PeriodicalId":402696,"journal":{"name":"CHI '09 Extended Abstracts on Human Factors in Computing Systems","volume":"239 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132946321","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 report on their motivations to volunteer, obstacles to volunteering, and strategies they use to manage the demands of volunteering.

While there have been many studies of navigation design guidelines for using maps or speech- or tactile-based guidance in mobile devices, in this paper we propose an initial study of multimodal navigation design utilising the theory of designing episodes of motion originating from urban planning. The implications of designing cues and providing rhythm, as the theory of episodes of motions suggests, are explored, with pedestrians as the subjects using wayfinding tasks in an urban area. The main contributions of this paper are in investigating the design principles, evaluating them in the context of mobile wayfinding tasks, and reflecting upon the results in terms of users' wayfinding behaviour. It is concluded that by designing predictive clues and rhythm into mobile multimodal navigation applications, we can improve navigation aids for users.","PeriodicalId":402696,"journal":{"name":"CHI '09 Extended Abstracts on Human Factors in Computing Systems","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132921093","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}

The slit-tear visualization technique is a generalization of the traditional photographic slit-scanning and more recent video slicing techniques: after a user specifies a pixel path of interest, the system generates a timeline that replicates those pixels for each frame in the video. These rich visualizations of the video data help users to discover and explore spatio-temporal patterns of activity in a video. In this video, we illustrate the use of slit-tear visualizations to detect movement and incidence of activity in a video scene, accentuate directional motion and small changes in the video, and discover patterns of activity between spatially distinct areas of the scene.","PeriodicalId":402696,"journal":{"name":"CHI '09 Extended Abstracts on Human Factors in Computing Systems","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115444396","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}
