   "title": "Is it Real? Measuring the Effect of Resolution, Latency, Frame rate and Jitter on the Presence of Virtual Entities",
   "abstract": "The feeling of presence of virtual entities is an important ob-\r\njective in virtual reality, teleconferencing, augmented reality,\r\nexposure therapy and video games. Presence creates emotional\r\ninvolvement and supports intuitive and efficient interactions.\r\nAs a feeling, presence is mostly measured via subjective ques-\r\ntionnaire, but its validity is disputed. We introduce a new\r\nmethod to measure the contribution of several technical pa-\r\nrameters toward presence. Its robustness stems from asking\r\nparticipant to rank contrasts rather than asking absolute val-\r\nues, and from the statistical analysis of repeated answers. We\r\nimplemented this method in a user study where virtual entities\r\nwere created with a handheld perspective corrected display.\r\nWe evaluated the impact on two virtual entities’ presence of\r\nfour important parameters of digital visual stimuli: resolu-\r\ntion, latency, frame rate and jitter. Results suggest that jitter\r\nand frame rate are critical for presence but not latency, and\r\nresolution depends on the explored entity.",
