在“增強(qiáng)頭戴顯示器中圖像顯示”的專利申請中,蘋果公司聲稱其方法“為頭戴顯示器用戶提供了更寬的視野以及創(chuàng)造了更為自然的觀看情形,從而改進(jìn)了頭戴顯示器的舒適度以及可用性?！?p>
在蘋果公司現(xiàn)有的產(chǎn)品當(dāng)中,如iPod,如果利用一塊小的視頻屏幕,將因佩戴頭戴顯示器而獲得最大的好處。盡管對于所描述的頭戴顯示器來說,蘋果公司并未特指iPod就是可能的視頻源,但是,其專利申請指出“外部源可以是一臺便攜式設(shè)備。”
第二項(xiàng)專利“用于頭戴顯示器的外設(shè)處理”中提出了一種“采用微機(jī)電(MEMS)/激光顯示器架構(gòu)”的系統(tǒng)。通過采用一種MEMS激光顯示器,蘋果公司希望避免現(xiàn)有的頭戴顯示器所存在的問題,也就是說,觀察盒子內(nèi)部可能因外圍視覺受限所帶來的不適感以及運(yùn)動不適感。
雖然蘋果公司指出,OLED以及LCoS微顯示器存在的缺點(diǎn)是壽命、分辨率以及幻覺效應(yīng)以及其它問題,但是,它也承認(rèn)采用MEMS激光系統(tǒng)可能存在的問題。第二個專利申請指出,MEMS激光“目前對安全性以及功耗存在一些擔(dān)心?！?p>
蘋果公司解決上述擔(dān)憂的能力將可能決定其iGlasses是否會以及何時成為現(xiàn)實(shí)。在iPod引起的傷害聽力問題上,蘋果公司已經(jīng)遭遇了各方批評,因此,蘋果公司不會急切地避免發(fā)布一款可能損傷佩戴者視覺的頭戴顯示器。

Apple patent may be prelude to iGlasses
Apple on Thursday filed two patent applications that describe improvements in head-mounted displays, which typically combine one or two small display screens with magnifying lenses inside a helmet or glasses.
In "Enhanced Image Display In Head-Mounted Displays," Apple claims that its approach provides "a wider field of view and [creates] a more natural viewing situation for a user of a head mounted display, which results in improved comfort and usability for head mounted displays."
Among Apple's current products, the iPod, with its small video screen, would benefit the most from a head-mounted display. While Apple does not specifically cite its iPod as a possible video source for wearers of the described head-mounted display, its patent application points out that the "external source can be a portable source."
The second patent,"Peripheral Treatment For Head-Mounted Displays," calls for a system using "a micro-electro-mechanical (MEM)/Laser display architecture." By using a MEM laser display, Apple hopes to avoid problems with existing head-mounted displays, namely the sensation of looking into a box and motion sickness that may be caused by limiting peripheral vision.
While Apple points out the shortcomings of OLED and LCoS microdisplays -- longevity, resolution, and rainbow effects, among others -- it also acknowledges potential issues with MEM laser systems. The second patent application notes that with MEM lasers, "there are currently some concerns about safety and power consumption."
Apple's ability to address those concerns will likely determine if and when its iGlasses become a reality. Having already weathered criticism about iPod-induced deafness, Apple no doubt is eager to avoid releasing a head-mounted display that might damage a wearer's vision.
