In particular, navigation in such environments is a significant problem.<\/p>\n\n\n\n<p>The first paper focuses on travel and describes the design and evaluation of two navigation techniques for&nbsp;multi-scale&nbsp;virtual environments (MSVEs). Issues such as spatial orientation and understanding were addressed in the design process of the navigation techniques. The evaluation of the techniques was done with two experimental and two control groups. The results show that the techniques we designed were significantly better than the control conditions with respect to the time for task completion and accuracy.<\/p>\n\n\n\n<p>The second paper focuses on wayfinding and&nbsp;on the understanding and classification of information needed for travel, as well as on the design of navigation techniques that provide this information. To this end, we first identified two kinds of information necessary for traveling effectively in this kind of environment: hierarchical information, based on the hierarchical structure formed by the levels of scale; and spatial information, related to orientation, distance between objects in different levels of scale and spatial localization. Based on this, we designed and implemented one technique for each kind of information. The developed techniques were evaluated and compared to a baseline set of travel and wayfinding aid techniques for traveling through multiple scales. Results show that the developed techniques perform better and provide a better solution for both travel and wayfinding aid.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-4-3 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Navigation Techniques for Multiscale Virtual Environments\" width=\"1333\" height=\"1000\" src=\"https:\/\/www.youtube.com\/embed\/qsfwWm6O23c?modestbranding=1\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n<div class=\"teachpress_pub_list\"><form name=\"tppublistform\" method=\"get\"><a name=\"tppubs\" id=\"tppubs\"><\/a><\/form><div class=\"teachpress_publication_list\"><h3 class=\"tp_h3\" id=\"tp_h3_conference\">Conferences<\/h3><div class=\"tp_publication tp_publication_conference\"><div class=\"tp_pub_info\"><p class=\"tp_pub_author\">Felipe Bacim; Doug A Bowman; Marcio S Pinho<\/p><p class=\"tp_pub_title\">Wayfinding Techniques for MultiScale Virtual Environments <span class=\"tp_pub_type tp_  conference\">Conference<\/span> <\/p><p class=\"tp_pub_additional\"><span class=\"tp_pub_additional_booktitle\">IEEE Symposium on 3D User Interfaces, <\/span><span class=\"tp_pub_additional_address\">Lafayette, Louisiana, <\/span><span class=\"tp_pub_additional_year\">2009<\/span>.<\/p><p class=\"tp_pub_menu\"><span class=\"tp_bibtex_link\"><a id=\"tp_bibtex_sh_88\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('88','tp_bibtex')\" title=\"Show BibTeX entry\" style=\"cursor:pointer;\">BibTeX<\/a><\/span><\/p><div class=\"tp_bibtex\" id=\"tp_bibtex_88\" style=\"display:none;\"><div class=\"tp_bibtex_entry\"><pre>@conference{4902,<br \/>\r\ntitle = {Wayfinding Techniques for MultiScale Virtual Environments},<br \/>\r\nauthor = {Felipe Bacim and Doug A Bowman and Marcio S Pinho},<br \/>\r\nyear  = {2009},<br \/>\r\ndate = {2009-03-01},<br \/>\r\nbooktitle = {IEEE Symposium on 3D User Interfaces},<br \/>\r\npages = {67-74},<br \/>\r\naddress = {Lafayette, Louisiana},<br \/>\r\nkeywords = {},<br \/>\r\npubstate = {published},<br \/>\r\ntppubtype = {conference}<br \/>\r\n}<br \/>\r\n<\/pre><\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('88','tp_bibtex')\">Close<\/a><\/p><\/div><\/div><\/div><div class=\"tp_publication tp_publication_conference\"><div class=\"tp_pub_info\"><p class=\"tp_pub_author\">Regis Kopper; Tao Ni; Doug A Bowman; Marcio S Pinho<\/p><p class=\"tp_pub_title\">Design and Evaluation of Navigation Techniques for Multiscale Virtual Environments <span class=\"tp_pub_type tp_  conference\">Conference<\/span> <\/p><p class=\"tp_pub_additional\"><span class=\"tp_pub_additional_booktitle\">Proceedings of IEEE Virtual Reality, <\/span><span class=\"tp_pub_additional_year\">2006<\/span>.<\/p><p class=\"tp_pub_menu\"><span class=\"tp_bibtex_link\"><a id=\"tp_bibtex_sh_119\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('119','tp_bibtex')\" title=\"Show BibTeX entry\" style=\"cursor:pointer;\">BibTeX<\/a><\/span><\/p><div class=\"tp_bibtex\" id=\"tp_bibtex_119\" style=\"display:none;\"><div class=\"tp_bibtex_entry\"><pre>@conference{3940,<br \/>\r\ntitle = {Design and Evaluation of Navigation Techniques for Multiscale Virtual Environments},<br \/>\r\nauthor = {Regis Kopper and Tao Ni and Doug A Bowman and Marcio S Pinho},<br \/>\r\nyear  = {2006},<br \/>\r\ndate = {2006-01-01},<br \/>\r\nbooktitle = {Proceedings of IEEE Virtual Reality},<br \/>\r\npages = {175-182},<br \/>\r\nkeywords = {},<br \/>\r\npubstate = {published},<br \/>\r\ntppubtype = {conference}<br \/>\r\n}<br \/>\r\n<\/pre><\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('119','tp_bibtex')\">Close<\/a><\/p><\/div><\/div><\/div><\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>The design of virtual environments for applications that have several&nbsp;levels&nbsp;of scale has not been deeply addressed.
