Thus salience is commonly viewed both as a basis for predicting where graph readers are likely to look, and as a core design technique for emphasizing what a reader is intended to see among competing elements in a given chart or plot. We briefly review models, metrics, and applicable theories as they pertain to graphs. We then introduce new saliency models based on perceptual and cognitive theories that, to our knowledge, have not been previously applied to models for viewing statistical graphics. The resulting frameworks can be broadly classified as bottom-up perceptual models or top-down cognitive models. We report the results of evaluating these new theory-informed approaches on gaze data collected for statistical graphs and for more general information visualizations. Interestingly, the new models fare no better than previous ones. We review the experience, noting why we expected these hypotheses to be effective, and discuss how and why their performance did not match our aspirations. We suggest directions for future research that may help to clarify some of the issues raised.","PeriodicalId":434621,"journal":{"name":"ACM Symposium on Applied Perception 2020","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126860529","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}

While there exist several naturally-mapped interfaces, these have not been directly compared – in terms of presence, engagement, perceived performance, and real performance – to a more commonly-used interface for interacting with virtual reality: the gamepad. Because gamepads have evolved over several decades and have widespread adoption, it is pragmatic to ask whether it is viable to import them into the design of VR experiences. To study this, we developed a first-person shooter (FPS) Virtual environment and contrasted the VR experience using the Microsoft Xbox 360 controller against the HTC VIVE wand. We assessed the effect of the input device on self-reported presence, engagement, and performance as well as real performance in terms of accuracy and speed, two metrics relevant for our particular environment. A within-subjects FPS shooting task under accuracy and time constraints confirmed our hypotheses in favor of the VIVE wand: presence, engagement, perceived performance, and real performance were deemed significantly higher than the Xbox controller condition. These results are contextualized with participants‘ comments in a post-experiment debrief, in which (paradoxically) several participants reported preferring the gamepad. We discuss the implications of our findings and how what we call genre fidelity can impact the design of VR experiences.","PeriodicalId":434621,"journal":{"name":"ACM Symposium on Applied Perception 2020","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126324090","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}

Predicting movement enables quick and appropriate action by both humans and artificial agents in many situations, e.g. when the interception of objects is important. We use different predictive movement primitive (MP) models to probe the visual system for the employed prediction mechanism. We hypothesize that MP-models, originally devised to address the degrees-of-freedom (DOF) problem in motor production, might be used for perception as well. In our study we consider object passing movements. Our paradigm is a predictive task, where participants need to discriminate movement continuations generated by MP models from the ground truth of the natural continuation. This experiment was conducted first in VR, and later on continued as online experiment. We found that results transfer from the controlled and immersive VR setting with movements rendered as realistic avatars to a simple and COVID-19 safe online setting with movements rendered as stick figures. In the online setting we further investigate the effect of different occlusion timings. We found that contact events during the movement might provide segmentation points that render the lead-in movement independent of the continuation and thereby make perceptual predictions much harder for subjects. We compare different MP-models by their capability to produce perceptually believable movement continuations and their usefulness to predict this perceptual naturalness. Our research might provide useful insight for application in computer animation, by showing how movements can be continued without violating the expectation of the user. Our results also contribute towards an efficient method of animating avatars by combining simple movements into complex movement sequences.","PeriodicalId":434621,"journal":{"name":"ACM Symposium on Applied Perception 2020","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125044501","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 first experiment, targets were presented in a circular configuration of 13 targets in accordance with the ISO 9241-9 Fitts’ Law standard, with a target distance of 5, 9 or 18 cm and target width of 0.65, 0.85, or 1.05cm, and with each circular configuration presented in a random distance of 60%, 75% or 90% of maximum arms length of the participant. The targets were centered at eye level, and in a within-subjects protocol participants selected the targets using a pointer at the tip of the controller or at the tip of their index finger on the dominant hand in the pointing based condition. The second experiment presented each target in a similar width and distance configuration as the previous experiment, but each target also varied in depth from one trial to the next between 60%, 75% or 90% of maximum arms reach. The selections were performed in an HTC Vive head mounted display VR world, using the popular Leap Motion gesture tracking device or the Vive controller. The results of both our experiment taken together revealed that with commodity 3D input devices, participants were more efficient in spatial selection performance in the popular controller based condition, as compared to the pointing based condition. Implications for VR developers and consumers are discussed in the latter sections.","PeriodicalId":434621,"journal":{"name":"ACM Symposium on Applied Perception 2020","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129686165","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 particular, depending on the target application, one may want to look like a dwarf or an elf in a heroic fantasy world, or like an alien on another planet, in accordance with the style of the narrative. While creating such virtual replicas requires stylization of the user’s features onto the virtual character, no formal study has however been conducted to assess the ability to recognize stylized characters. In this paper, we present a perceptual study investigating the effect of the degree of stylization on the ability to recognize an actor, and the subjective acceptability of stylizations. Results show that recognition rates decrease when the degree of stylization increases, while acceptability of the stylization increases. These results provide recommendations to achieve good compromises between stylization and recognition, and pave the way to new stylization methods providing a tradeoff between stylization and recognition of the actor.","PeriodicalId":434621,"journal":{"name":"ACM Symposium on Applied Perception 2020","volume":"339 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124772344","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}
