有一些方法可以绕过这个问题,但远没有那么方便:很少有人有空间或金钱来购买一个巨大的多方向跑步机。还有 "原地行走 "的方法,也不是很好。Ekto VR的第一款产品Ekto One则采用了不同的方式。据UploadVR报道,Ekto One是一双轻巧的机器人靴子,每个设备的底部都有两个旋转板。当你向前行走时,靴子会向后滑行,让你保持在同一个地方,就像穿着轮滑鞋时行走,它还有一套刹车装置,当你站立不动时,就会施加刹车,防止你摔倒。
一段视频展示了Ekto One在《半条命Alyx》中使用。这个概念看起来确实很酷,但也有一些明显的缺点。使用者必须非常缓慢地移动,这在《毁灭战士》这样的FPS游戏中可不是你想要的,而且有些时候看起来很不稳定。老实说,穿着一双巨大的旱冰鞋,拿着两个控制器,戴着一个巨大的头盔,走来走去并不是一个简单的任务,你绝对不会想尝试穿着这些东西冲刺,也不知道它们在地毯上会不会很好用。
不过,目前的Ekto One型号是为企业解决方案而生的,所以在两到四年后的消费者版本上可能会有一些改进。
