Two-point interaction has become common, e.g., when zooming or pinching using two fingers on a smartphone. We propose a novel interaction technique that implements three-point interaction by augmenting two-finger direct touch with gaze as a third input channel. We evaluate two key characteristics of our technique in two multi-participant user studies. In the first, we used the technique for object selection. In the second, we evaluate it in a 3D matching task that requires simultaneous continuous input from fingers and the eyes. Our results show that in both cases participants learned to interact with three input channels without cognitive or mental overload. Participants' performance tended towards fast selection times in the first study and exhibited parallel interaction in the second. These results are promising and show that there is scope for additional input channels beyond two-point interaction.","PeriodicalId":250565,"journal":{"name":"Proceedings of the International Working Conference on Advanced Visual Interfaces","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133426626","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}

Unfortunately, keywords-based techniques suffer from the semantic gap existing between a semantic concept and its digital representation. Content Based Image Retrieval (CBIR) systems tackle this issue simply considering semantic proximities can be mapped to similarities in the image space. Introducing relevance feedbacks involves the user in the task, but extends the annotation step. To reduce the annotation time, we want to prove that implicit relevance feedback can replace an explicit one. In this study, we will evaluate the robustness of an implicit relevance feedback system only based on eye-tracking features (gaze-based interest estimator, GBIE). In [5], we showed that our GBIE was representative for any set of users using \"neutral images\". Here, we want to prove that it remains valid for more \"subjective categories\" such as food recipe.","PeriodicalId":250565,"journal":{"name":"Proceedings of the International Working Conference on Advanced Visual Interfaces","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131388084","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}

Our PIM retrieves events on the basis of both the user's context and event similarity, which is computed by exploiting an information retrieval technique. We aggregated together the similarity of content, location, time, and event type to relate and surf the events. To this aim, we propose a re-find interface enabling the user to search and visualize information already seen before, of which he remembers some context aspects, such as time and/or place. The events captured on different devices are stored on the cloud without user intervention. A preliminary quantitative and qualitative evaluation has been also conducted to assess the effectiveness of LifeBook. Results in terms of time, effort and relevance of the information provided suggest that LifeBook be a viable means to retrieve personal information. Participants in the empirical investigation also considered the tool appropriate for supporting information re-finding tasks.","PeriodicalId":250565,"journal":{"name":"Proceedings of the International Working Conference on Advanced Visual Interfaces","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114561082","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 use of 3D techniques to display information, and sorting techniques to arrange it are not new. Node-edge graphs predate computers, but their visualization in real-time, three-dimensional virtual reality is quite recent. Some efforts have been conducted by visualization researchers to verify the validity of these techniques, and some HCI experiments have been carried out in navigating 3D spaces. This paper describes a HCI framework to facilitate engagement in an immersive 3D virtual reality (VR) visualization, by means of a compound control system consisting of existing technologies, for navigation and highlighting, and a purpose built controller for selection and manipulation of data; within a software environment that was built using an existing real time 3D game engine.","PeriodicalId":250565,"journal":{"name":"Proceedings of the International Working Conference on Advanced Visual Interfaces","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132122419","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}

Measurement iterations produce a series of time-oriented data, which stakeholders as well as the general public might be interested to interpret. Visualization of a CI is highly recommended in order to ease interpretation, and many CI websites use radial solutions to visualize CIs. Yet it is unclear how to visualize the temporal dynamics in radial diagrams. Static solutions, mapping time to small multiples might be challenging due to screen space issues. Dynamic solutions are appealing, yet, there is no clear empirical evidence on benefits of dynamic time coding in radial diagrams. In this paper, we compare static vs. dynamic time mapping using two radial CI visualization methods. The popular Radar chart technique is compared to the innovative Flower chart as used in the well-known OECD Better Life index. We compare users' performance and preferences empirically under formal task taxonomy, adjusted to CI tasks. Results indicate that in general, static time encoding was more effective than dynamic encoding. Still, an in depth analysis showed that the dynamic approach is a feasible and sometimes even better solution for important CIs tasks, leveraged by the fact that users seem to like and enjoy it.","PeriodicalId":250565,"journal":{"name":"Proceedings of the International Working Conference on Advanced Visual Interfaces","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127366935","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}
