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 提出只使用一顆馬達的 Base Station 的 Solution
2. 能將 Vive 系統最貴的 $134 鎂 Base Station 中的馬達兩顆變一顆
3. Vive 還在 finding/redesign/possible alternative solution 的階段，莫慌張
4. HTC 什麼都還沒有說
5. 改良過後的 Base Station 使得整體預估價: 799 鎂 -> 665鎂 => -17%

感謝 luyaoting 除錯
看了文中連結的另一篇較詳細的文章 (https://goo.gl/ttXx08)
其實是依然兩顆 Base Station
但是本來每顆 BaseStation 裡面有兩顆馬達各負責 X軸 跟 Y軸的偵測
變成每顆 BaseStation 裡只裝上一顆可偵測 V 型範圍的新馬達
