Therefore, in this work a state-of-the-art (STOA) image quality assessment (IQA) metric, gradient magnitude similarity deviation (GMSD) has been incorporated in a STOA least-square-based non-local means (NLM) filtering framework for image denoising. The denoising process works by estimating and weighting neighbouring patches similar to the patch being denoised in terms of Euclidean distance (ED) and GMSD coefficient. The overall process is broken down into two steps; initially, local noise estimates for the underlying noisy patch are approximated and removed, then the refined patch is fed to the weighting process as the final step. Further, the proposed methodology also helps in mitigating the patch jittering blur effect (PJBE) and over smoothing of denoised images as observed with conventional NLM algorithm. Experimental evaluations based on visual-quality assessment and least-square-based metrics have shown that the proposed algorithm yields better denoised image estimates than the conventional NLM algorithm. Moreover, experiments conducted on a subjective database, i.e. CSIQ, have shown higher performance in terms of peak signal-to-noise ratio (PSNR), structural similarity (SSIM) and GMSD coefficients. The resultant denoised images were in high correlation with the subjective judgements compared to the ones obtained with conventional NLM algorithm.","PeriodicalId":446032,"journal":{"name":"2019 IEEE International Symposium on Haptic, Audio and Visual Environments and Games (HAVE)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115570199","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 2013, the number of working days lost due to sickness absence in UK is 131 million days, and 23.66% of this number is contributed by back pain and neck pain victims [1]. In this paper, a preliminary study of posture recognition system has been developed, to rectify the user’s sitting posture by alerting him/her. A proper and improper sitting posture might look quite similar to each other in the eye of sensors, especially different heights and genders cause difficulties in detection. Hence, a preliminary posture recognition model that specifically tackles the recognition between a proper and an improper sitting posture has been developed. In this paper, we use Kinect sensor for the sitting postures detection, and then feed the postures data to the posture recognition models such as Support Vector Machine (SVM) and Artificial Neural Network (ANN), for training purpose. We compared these two models and found that SVM with linear kernel has the highest accuracy.","PeriodicalId":446032,"journal":{"name":"2019 IEEE International Symposium on Haptic, Audio and Visual Environments and Games (HAVE)","volume":"242 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122522924","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}

Traditional vibrotactile actuators are either low-cost with limited expressiveness of vibration cues or high-cost with great expressiveness. We designed, characterized, and perceptually evaluated a low-profile, low-cost vibrotactile actuator that can control frequency and intensity of vibration independently. The actuator characterization demonstrated its ability to display frequencies in a perceptually flat response for the frequency band (110-300 Hz). Furthermore, the vibration intensity can be controlled independently in the same frequency band (110–300Hz), producing a flat response. A psychophysics experiment is conducted to validate the perceptual capabilities of the actuator. It is found that the actuator can display perceptually distinct stimulation across the defined frequency and intensity bands. The proposed actuators can be used to develop ubiquitous vibrotactile stimulation with high expressivity at low cost.","PeriodicalId":446032,"journal":{"name":"2019 IEEE International Symposium on Haptic, Audio and Visual Environments and Games (HAVE)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133220066","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}

Leveraging those features, a new modulation technique producing spatially distributed tactile sensations has recently been introduced. This new approach, referred to as Spatiotemporal Modulation (STM), draws lines, curves and shapes on users’ palm by moving a mid-air tactile point rapidly and repeatedly along the path. STM parameters and their impact on tactile perception are yet to be studied systematically. In this work, we first study how varying the draw frequency and the size of a simple shape affects the participants perception of texture and their emotional responses. In the second part of our study, we used the most salient tactile patterns of the first study to extend the results within a multimodal context. We found that tactile patterns’ perception was consistent within both studies. We also found instances when the tactile patterns could alter the perception of the audio and visual stimuli. Finally, we discuss the benefits of our findings and conclude with implications for future work.","PeriodicalId":446032,"journal":{"name":"2019 IEEE International Symposium on Haptic, Audio and Visual Environments and Games (HAVE)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115990269","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}

Besides, e-learning or virtual learning has benefited for visually impaired (VI) learners. There are several studies confirmed that VI learners acknowledge the potentials and advantages of e-learning or virtual learning systems. However, not like sighted learning, VI learners face several challenges in using e-learning materials which are available on the shelf. Most of the virtual learning environments are designed for sighted learning and rich utilization of images and interactivities result the restrictions for the VI to use learning platforms in a virtual environment. Most of the VI learners are relying on screen reader to translate the contents from screen or documents. Thus, careful consideration is important in designing the learning environment for VI according to their requirements and accessibility to provide engaging virtual learning environment for them. Hence, this paper proposes a 3D enabled olfactory, haptic and audio (3DOHA) enhanced application for visually impaired learners to use in a virtual learning environment and evaluates the proposed application by conducting a pilot testing. Based on the study conducted, all the participants in this study agreed that the proposed system is fun to use and they would recommend it to their fellow friends to use in learning. Besides, the results show that the proposed 3DOHA is easy to use, easy to remember the steps to be taken to use the application and users would like to have 3DOHA application for learning.","PeriodicalId":446032,"journal":{"name":"2019 IEEE International Symposium on Haptic, Audio and Visual Environments and Games (HAVE)","volume":"189 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124319812","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}
