All humans are functionally blind for about 10 percent of the time under normal circumstances due to eye blinks and saccades, a rapid movement of the eye between two points or objects. Eye blinks are a common and natural cause of so-called "change blindness," which indicates the inability for humans to notice changes to visual scenes. Zeroing in on eye blinks and , the team has devised a novel computational system that effectively redirects the user in the virtual environment during these natural instances, all with undetectable camera movements to deliver orientation redirection.
"Previous RDW [redirected walking] techniques apply rotations continuously while the user is walking. But the amount of unnoticeable rotations is limited," notes Eike Langbehn, lead author of the research and doctoral candidate at the University of Hamburg. "That's why an orthogonal approach is needed—we add some additional rotations when the user is not focused on the visuals. When we learned that humans are functionally blind for some time due to blinks, we thought, 'Why don't we do the redirection during eye blinks?'"
Human eye blinks occur approximately 10 to 20 times per minute, about every 4 to 19 seconds. Leveraging this window of opportunity—where humans are unable to detect major motion changes while in a —the researchers devised an approach to synchronize a computer graphics rendering system with this visual process, and introduce any useful motion changes in virtual scenes to enhance users' overall VR experience.
The researchers' experiments revealed that imperceptible camera rotations of 2 to 5 degrees and translations of 4 to 9 cm of the user's viewpoint are possible during a blink without users even noticing. They tracked test participants' eye blinks by an eye tracker in a VR head-mounted display. In a confirmatory study, the team validated that participants could not reliably detect in which of two eye blinks their viewpoint was manipulated while walking a VR curved path. The tests relied on unconscious natural eye blinking, but the researchers say redirection during blinking could be carried out consciously. Since users can consciously blink multiple times a day without much effort, eye blinks provide great potential to be used as an intentional trigger in their approach.
The team will present their work at SIGGRAPH 2018, held 12-16 August in Vancouver, British Columbia. The annual conference and exhibition showcases the world's leading professionals, academics, and creative minds at the forefront of computer graphics and interactive techniques.
"RDW is a big challenge since current techniques still need too much space to enable unlimited walking in VR," notes Langbehn. "Our work might contribute to a reduction of space since we found out that unnoticeable rotations of up to five degrees are possible during blinks. This means we can improve the performance of RDW by approximately 50 percent."
The team's results could be used in combination with other VR research, such as novel steering algorithms, improved path prediction, and rotations during saccades, to name a few. Down the road, such techniques could some day enable consumer VR users to virtually walk beyond their living room.
Langbehn collaborated on the work with Frank Steinicke of University of Hamburg, Markus Lappe of University of Muenster, Gregory F. Welch of University of Central Florida, and Gerd Bruder, also of University of Central Florida. For the full paper and video, visit the team's project page.

智能医学产品评测
原始标题:
智能医学行业资讯每一天都给你新鲜的、AR:从游戏“跨界” 医疗绝非偶然今天,从我们的日常说起,毫无疑问的一个生活习惯是,我们人类这么多年来习惯了 “眼见为实”,而 VR、AR是 “眼见为虚”,在VR里看到的 “手” 不是自己真正的手,所以我们需要学习这种“互动规律”,让我们的双眼、大脑适应适应,要不然把握不好轻重。因此,VR、AR以游戏领域开始,再进入“医疗” 这种更“严肃”的领域还真不是巧合。怎么练习呢?打游戏无疑是一种很好的方式。通过打游戏,人们能慢慢适应在“”里怎么控制自己的手。等我们对 “下手轻重” 有更深了解后,才能做像手术这种更精细、对下手轻重要求更高的东西。为什么是 VR、AR + 医疗,而不是其他领域?这和VR、AR恰好能解决医疗业痛点有关:有了VR、AR,医护人员在学习新技能、练习手术操作时,就能历史上第一次在一个 “犯了错误也不要紧” 的环境下练习,反正这些错误不是“真的”。万一失误,也不会对患者造成危险。在这个前提下,VR/AR与医疗的结合基本上可以分成三类:第一类是“做手术” 类;第二类是“医师技能训练” 类;第三类是“患者康复训练” 类。01做手术:真实演练防失误在VR、AR的帮助下,患者能和医生一起“走进”他的身体里,制定更精准的治疗方案。医疗领域VR的创业公司 Surgical Theater 做的就是这件事。这家公司的 “精准VR” 功能受到战斗机飞行员的启发:战斗机飞行员在真实飞行之前,往往会在模拟机舱里飞几遍,这样等真正飞的时候就能熟练一些。因此,他们为每位患者量身定做一个三百六十度的虚拟现实,重现患者身体的病灶,这样医生就能带着患者一起“钻”进患者的身体,而且还能在里面像逛商场一样四处逛一逛,看看病灶,然后医生和患者一起商量制定治疗方案。等到真的上了手术台进行手术时,医生由于之前已经 “预习” 过,对患者的情况就会很熟悉,这样突发状况也会少很多。另外,以色列的创业公司 Augmedics 目前正在致力于给进行脊柱手术的外科医生开发增强现实耳机。看来,VR更倾向于 “术前准备”,而AR的作用在手术过程中更能体现出来。02模拟练习柳叶刀医生手里的柳叶刀直接关乎手术台上病人的康复情况,甚至能决定生死。用VR训练外科医生,就能减少手术中错误的发生。外科医生戴好专有的 VR眼镜后在模拟器上做手术,手术刀的角度、下手轻重,全都能体现在虚拟的患者身上。每个人身体不一样,再有经验的医生也有拿不准的时候,有了虚拟现实,外科医生们就能先练习练习,提高在真实手术中的表现。03真实互动助康复大家都知道,烧伤患者复健的道路通常既漫长、又痛苦。洛杉矶就有家医院开始尝试用VR引领患者进入身临其境的游戏里,让患者从被烧伤的痛苦里转移注意力,缓解焦虑、更加放松。有些烧伤患者在佩戴VR眼镜后,降低了止疼片需要的剂量, 而且不是只有戴着VR眼镜时暂时减少止疼片,而是烧伤患者摘了VR眼镜一段时间后、长期减少了对止疼片的需求。除了烧伤患者,有些脑部受到损伤的患者在康复过程中也会受到不小的挑战。神经技术创业公司 MindMaze 近期就创建了一个VR应用程序,通过激发患者的视觉和听觉参与,这个应用程序不断地鼓励患者进行重复运动,比如重复用手拿起一个苹果、然后放在桌子上,然后再拿起来、再放下...... 这种重复运动能够加快神经系统的恢复,对脑卒中或脑损伤患者来说是史无前例的新方法,难怪这家公司创业没多久就被估值10亿美元了。因此,虽然现在想进军医疗领域的VR/AR公司多得像雨后春笋,看上去一片繁荣,但是作为新兴领域,VR/AR的技术非常新颖,在其在医疗领域成规模应用之前还需要大规模的研究。精品资料NEW2018年中国健康保障行业研究报告公众号后台回复"报告"轻松免费获取同时加我微信也可免费获取价值599元的自我救护课程。-END-快来看,更多精彩都在这里!&▼智能医学行业资讯每一天都给你新鲜的
