An abundance of haptic rendering schemes have been developed to help further presence and immersion in virtual environments. Increasing realism is the main driving force behind this development. Schemes have progressed from simple one-dimensional springs to six degree of freedom particle models, with a wealth of surface and material properties. Because of their relative unimportance, haptic ren...

Video-based action quality assessment (AQA) is a non-trivial task due to the subtle visual differences between data produced by experts and non-experts. Current methods are extended from recognition domain where most based on temporal pattern matching. AQA has additional requirements order tempo matter for rating of an action. We present novel dataset ranked TikTok dance videos, pairwise method...

Recently an impressive development in immersive technologies, such as Augmented Reality (AR), Virtual (VR) and 360${^\circ }$ video, has been witnessed. However, methods for quality assessment have not keeping up. This paper studies of video from the cross-lab tests (involving ten laboratories more than 300 participants) car...

In modern video conferencing services, just as in common video delivery, most of the resource optimization is taken care of in the codec layer. Modern codecs like H.264 use detailed perceptual models to optimize the data reduction in way that it is least noticed by us. Already early evaluations of telecommunication systems could establish that there are different thresholds for a good quality d...

BACKGROUND AND STUDY AIMS Anxiety before colonoscopy may have adverse consequences and increase requirements for sedation and analgesics. We aimed to examine the effects of adding an information video to our usual preprocedural information. PATIENTS AND METHODS 162 colonoscopy patients were randomly assigned to video (72) or no video (90) groups. Patients in the video group watched a video on...
