Applicant’s preliminary amendment dated 03/08/2024 has been received and entered. By the amendment, claims 1-1 are now pending in the application.
Information Disclosure Statement
The information disclosure statement (IDS) submitted on 03/08/2024 was filed and considered by the examiner.
Specification
The lengthy specification has not been checked to the extent necessary to determine the presence of all possible minor errors. Applicant’s cooperation is requested in correcting any errors of which applicant may become aware in the specification.
Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 7-8 are rejected under 35 U.S.C. 103 as being unpatentable over Bai et al., US 2024/0231116 A1, in view of Luo, CN 217587771 U.
Regarding claim 7, Bai et al. disclose a virtual reality (VR) device 1 (figs 1-4) comprising:
. two sets of lens systems 20, wherein each set of the lens system 20 comprises one convex lens 210 and one concave lens 230, and the concave lens 230 is disposed between the convex lens 210 and the display screen 10
. a display screen 10
. the lens system is movable ([0072]) with a lens spacing (figs 3-4, [0050]).
Bai et al., however, do not disclose a sliding rheostat respectively connected to a processor, wherein one sliding rheostat device is provided on at least one of the lens systems; wherein a sliding pin of the sliding rheostat device is fixedly connected to the concave lens, and the sliding pin is movable with the concave lens, an input pin and the sliding pin of the sliding rheostat device are respectively electrically connected to the processor, and wherein the processor is configured to acquire a voltage of the sliding rheostat device, ; the voltage of the sliding rheostat device is a voltage between the sliding pin and the input pin; the voltage of the sliding rheostat device and the lens spacing have the pre-obtained corresponding association relationship. Luo does disclose a VR device for a head-mounted display device having a control device 50, for detecting the real-time resistance value of a sliding rheostat 41, according to the real-time resistance value, obtaining the current pupillary distance of the lens assembly 30, and controlling the lens assembly 30 to display the current pupil distance, in which the head-mounted display device can adjust the pupillary distance between two lens components through pupillary distance adjusting component. the application model is further added with a first sliding rheostat and a control device connected with the power supply on the bracket, two pins of the first sliding rheostat are respectively connected with the positive electrode and the negative electrode of the power supply, the sliding pin of the first sliding rheostat is fixedly connected with one of the lens assembly, the control device is used for detecting the real-time resistance value of the sliding rheostat, and according to the real-time resistance value, obtaining the current pupillary distance of the lens assembly (figs 2, 4 and [0028]). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to employ a processor, a sliding rheostat device and their assembly relationships over the Bai et al. VR device, as shown by Luo, to ensure visual effects and automation.
It is noted that the limitation of “configured to obtain the lens spacing by calculating based on the voltage of the sliding rheostat device and the pre-obtained corresponding association relationship” recites a one-step process which does not further limit the structure of the device claims. Therefore, this limitation has not been given patentable weight
Re claim 8, the modification to Bai et al. would result the processor to execute and control the VR device (Luo, [0028]).
Allowable Subject Matter
Claims 1-6 and 9-10 are allowed.
The following is a statement of reasons for the indication of allowable subject matter:
None of the prior art of record discloses or suggests alone or in combination that a regulation and control method for a VR device comprising a combination of various steps as claimed more specifically the step of obtaining a first corresponding relationship and a second corresponding relationship, wherein the first corresponding relationship is a corresponding relationship between a lens spacing and a field of view of the lens system, the second corresponding relationship is a corresponding relationship between the lens spacing and a visible area on the display screen, and the lens spacing is a distance between the convex lens and the concave lens, the step of obtaining a current lens spacing, and obtaining a first field of view according to the first corresponding relationship, wherein the first field of view is a field of view corresponding to the current lens spacing and adjusting a display area of the display screen to be completely located in the first visible area, wherein the first visible area is a visible area corresponding to the current lens spacing as set forth in claims 1 and 6.
Claims 2-6 and 9-10 are allowed by virtue of their dependency.
