20.500.12556/RUL-130502 Exploring direct 3D interaction for full horizontal parallax light field displays using leap motion controller This paper reports on the design and evaluation of direct 3D gesture interaction with a full horizontal parallax light field display. A light field display defines a visual scene using directional light beams emitted from multiple light sources as if they are emitted from scene points. Each scene point is rendered individually resulting in more realistic and accurate 3D visualization compared to other 3D displaying technologies. We propose an interaction setup combining the visualization of objects within the Field Of View (FOV) of a light field display and their selection through freehand gesture tracked by the Leap Motion Controller. The accuracy and usefulness of the proposed interaction setup was also evaluated in a user study with test subjects. The results of the study revealed high user preference for free hand interaction with light field display as well as relatively low cognitive demand of this technique. Further, our results also revealed some limitations and adjustments of the proposed setup to be addressed in future work. 3D display light field display free-hand interaction direct touch Leap Motion Controller human-machine interface HMI HCI tridimenzionalni zalon light field zaslon prostoročna interakcija neposredni dotik Leap Motion Controller vesnik človek-stroj komunikacija človek-stroj true false true Angleški jezik Slovenski jezik Članek v reviji 2021-09-15 15:21:21 2021-09-15 15:21:22 2023-05-26 03:41:40 0000-00-00 00:00:00 2015 0 0 Str. 8642-8663 iss. 4 Vol. 15 Apr. 2015 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 004.353:004.5 1424-8220 10.3390/s150408642 10992468 RAZ_Adhikarla_Vamsi_Kiran_2015.pdf RAZ_Adhikarla_Vamsi_Kiran_2015.pdf 1 EEEB267ADA62D5CD34BEF6B3BAB7344E cbbf99d17f97989af92a30d9f95e04f29ff76c70de3743572730cf0e9ddf82fc db77e2bf-1627-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=147623 http://www.mdpi.com/1424-8220/15/4/8642 1 908f63a2-1627-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=147622 Fakulteta za elektrotehniko 0 0 0
