Virtual Reality technology is a bit pricey that makes people think twice on
trying to explore the VR world. Because of this, Valve has brought good news
to VR fans as it is trying to find for alternative construction systems for
its SteamVR Tracking Base Stations aiming to reduce HTC Vive cost by removing
unnecessary components.
According to Digital Trends, potential innovations can make internal
machinery simple without a blow to its performance, trimming down the buy-in
value for an HTC Vive unit around $100 or more while the Lighthouse Base
Stations are one of the most high-priced components as a requirement for
SteamVR Tracking. The SteamVR Tracking needs two Tracking Base Stations to
perform, which is a requisite that contributes to the high price value of the
HTC Vive.
A Tracking Base Station replacement costs $134 via HTC's online storefront
that is possibly the priciest part of the HTC Vive system beyond the headset,
reports Road to VR. Ben Jackson, the Valve engineer suggested a
penny-pinching solution during the Valve's Steam Dev event.
Jackson said that the Tracking Base Stations currently uses a pair of motors
to trace movements and every motor needs its own laser diode and controller
driving up the cost of HTC Vive by a considerable margin. He suggested a
single-motor solution, which can trim down the hardware production of the
Tracking Base Station in half.
Jackson's design shows that a single motor produces a V-shaped laser outline
in the VR play section, which simultaneously gathers X and Y axis information
without a necessity to add a motor for fine tuning. "What better way to make
[the Base Station] lighter, quieter, cheaper and more power-efficient than to
chop out half the parts?" he asked.
Triad Semiconductor's Reid Wender said that the possible redesigning of the
Tracking Base Stations is a rapid cost reduction. Although Valve has not
announced its plans of redesigning the current units, the estimated
cost-cutting method can cut the price of HTC Vive down to $665, which is
around 17 percent less than its price at the moment.
心得:
1. Vive 的 RD 提出只使用一颗马达的 Base Station 的 Solution
2. 能将 Vive 系统最贵的 $134 镁 Base Station 中的马达两颗变一颗
3. Vive 还在 finding/redesign/possible alternative solution 的阶段，莫慌张
4. HTC 什么都还没有说
5. 改良过后的 Base Station 使得整体预估价: 799 镁 -> 665镁 => -17%

感谢 luyaoting 除错
看了文中连结的另一篇较详细的文章 (https://goo.gl/ttXx08)
其实是依然两颗 Base Station
但是本来每颗 BaseStation 里面有两颗马达各负责 X轴 跟 Y轴的侦测
变成每颗 BaseStation 里只装上一颗可侦测 V 型范围的新马达
