請參照第9圖,其繪示根據本發明另一實施例之虛擬實境系統700之方塊圖。在本實施例中,控制單元518設置於主機720中,其餘相同之處不在重複敘述。控制單元518連接於頭戴式顯示裝置710之外置追蹤單元111及內置追蹤單元112,以調整對外置追蹤單元111之第一權重W1及內置追蹤單元112之第二權重W2。 Please refer to FIG. 9, which is a block diagram of a virtual reality system 700 in accordance with another embodiment of the present invention. In this embodiment, the control unit 518 is disposed in the host 720, and the rest of the same is not repeated. The control unit 518 is connected to the head mounted display device 710 external tracking unit 111 and the built-in tracking unit 112 to adjust the first weight W1 of the external tracking unit 111 and the second weight W2 of the built-in tracking unit 112.
根據上述各種實施例,頭戴式顯示裝置同時設置外置追蹤單元及內置追蹤單元,使得頭戴式顯示裝置能夠適用於各種不同的虛擬實境內容,擴大了虛擬實境技術的發展。 According to the various embodiments described above, the head mounted display device simultaneously sets the external tracking unit and the built-in tracking unit, so that the head mounted display device can be applied to various virtual reality content, and the development of the virtual reality technology is expanded.
綜上所述,雖然本發明已以實施例揭露如上,然其並非用以限定本發明。本發明所屬技術領域中具有通常知識者,在不脫離本發明之精神和範圍內,當可作各種之更動與潤飾。因此,本發明之保護範圍當視後附之申請專利範圍所界定者為準。 In conclusion, the present invention has been disclosed in the above embodiments, but it is not intended to limit the present invention. A person skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
