Despite the availability of modern graphics hardware, such real-time high fidelity graphics is still not feasible on a single PC. Research on visual perception has shown that the perceived quality of rendered graphics depends not only on the fidelity of the generated imagery but also on the characteristics of visual attention and the limitations of the human visual system. The findings of this research have been used to define perceptually driven criteria for rendering with the aim to reduce rendering times. Furthermore, in reality there are strong crossmodal interactions between auditory and visual stimuli, with a number of studies showing that stimuli reaching the various senses are not, in general, processed independently. In this paper we investigate whether auditory stimuli, and more specifically sound effects with abrupt onsets, affect a viewer's perceived quality of rendered images while watching computer generated animations. In fact, we show how we can potentially accelerate the rendering of animations by directing the viewer's attention towards the source of a sound and selectively render at high quality only the sound emitting object. For this purpose a renderer was implemented which selectively renders the sound emitting objects and the surrounding pixels to high quality while the rest of the scene is rendered at a significantly lower quality. A psychophysical experiment with 120 participants was run which revealed a significant effect of sound effects on the perceived rendering quality. Our results show that audio stimuli, and in particular sound effects, can be exploited when rendering animations, to significantly reduce rendering time without any loss in the user's perception of delivered quality.","PeriodicalId":286067,"journal":{"name":"Proceedings of the 3rd international conference on Computer graphics and interactive techniques in Australasia and South East Asia","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130360719","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, in our changing world, it is necessary to connect not only humans to the computer world, but also to develop interfaces for entities such as animals and plants. We have developed and tested some interfaces allowing us to study the effects of different kinds of interaction and how people change their perception of other virtual and living entities. These interfaces allow the user to have contact with other living beings, such as plants and animals, in unique ways that provide a better understanding of their \"feelings\". In the specific case of plants, this is achieved by transforming the measurement of changes in the soil where the plant is into humanly abstracted experiences, such as thirst, sadness and happiness. These events are processed and analyzed by a computer program that infers the current status of the plant so that this can be modeled like a FSM.One way to link the actions performed by the user with a desirable result in the virtual world is to effectively guess the user's needs and expectations. However, this is not always achieved. Tactile sensations, sounds and images can help us to immerse the user into our application, but in heterogeneous VR applications we need to include virtual references to connect all the entities in the Virtual world and change the way the user observes these entities. The following paper describes a Plant-Computer-Human interface involving a real and a virtual plant that was developed for VR and Art applications. We also describe the reactions of users to these applications.","PeriodicalId":286067,"journal":{"name":"Proceedings of the 3rd international conference on Computer graphics and interactive techniques in Australasia and South East Asia","volume":"158 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121488788","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}
