DETAILED ACTION
1. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claims 1-20 are presented for examination on the merits.
Claim Rejections - 35 USC § 102
2. 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 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.
3. The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention.
4. Claims 1-3 and 11-13 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Xie (CN 109828664 A)
As to claim 1, Xie discloses in steady-state visual evoked potential brain-computer interface method based on sensory feedback dynamic regulation having claimed:
a. a method for presenting visual feedback, the method comprising: receiving a steady-state visual evoked potential (SSVEP) signal extracted through an electroencephalogram (EEG) analysis of a user gazing at a visual stimulus of a specific frequency; classifying the visual stimulus to generate a classification result based on the SSVEP signal; disposing, on the visual stimulus, a visual feedback having a same frequency as the visual stimulus; and reflecting the classification result in the visual feedback in real time read on Claim 1, (First, the original brain wave signal filtering and notch processing, then, obtaining the processed EEG signal and a degree of correlation between the sine reference signal of different frequency, the related degree of the maximum turning corresponding to the frequency of the motion stimulating unit judges that user gaze target, marked as f-target; 3.4) to obtain the static result: when the stimulus presentation time N seconds. by step 3.3) to obtain an identification of the target f-target (0), and stimulation of the user gaze target to form an indication, represented by Fourier transform, the ratio of the sum of the amplitude value at the stimulation target frequency amplitude and all the target stimulation frequency, namely calculating proportion value; 3.5) dynamically adjusting on the basis of the obtained static result, seconds as sliding window length N to n seconds is the sliding step length, every after n seconds overlapping target f-target (m), re-judging whether the identifying; m is the sliding times, and re-calculating the size proportion value of the average level of the classification problem X circular checkerboard represents the set Y, namely Y=1/X, when the proportion value is more than Y, the ratio value has significance; and when the ratio value is not more than Y, the stimulation interface display real-time eye gaze position collected by the eye tracker, and the prompt tone indicating user need concentrating; step 4), judging whether ending the task: judging whether f-target (m) and f-target (m-1) are the same, wherein m=1, 2, ..., if they are not the same, this task to continue, if both are the same, this task is ended; step 5) to finish the target identification, returning to step 3) to perform the next target identification task).
As to claim 2, Xie further discloses:
a. wherein reflecting the classification result in the visual feedback in real time includes: varying a shape of a first visual feedback disposed in a first visual stimulus classified from among a plurality of visual stimuli in each of which the visual feedback is disposed according to the classification result to a first shape; and varying a shape of a second visual feedback disposed in a second visual stimulus that is not classified to a second shape read on Page 2, Para. 8, (displays the stimulation interface on the computer screen display X circular checkerboard composed by alternately arranging small square black-and-white, circular checkerboard as motion stimulation unit; circular checkerboard pattern for shrinking and expanding movement according to the sine rule, formed of two cycle turning movement direction, respectively located at different positions of the computer screen, and these circular checkerboard to overturn at a different stimulation frequency, stimulation frequency of each round chessboard grid are higher than 6Hz).
As to claim 3, Xie further discloses:
a. wherein reflecting the classification result in the visual feedback in real time includes: periodically collecting the classification result at preset time points within a maximum window length; calculating a count value with respect to the visual stimulus based on the classification result collected at each time point among the preset time points; and varying a shape of the visual feedback in real time based on the count value read on Page 4, Para. 9, (the original brain wave signal filtering and notch processing, then to obtain the processed EEG signal and a degree of correlation between the sine reference signal of different frequency. the related degree of the maximum turning frequency corresponding to the stimulation unit judges that user gaze target, marked as f-target; to obtain the static result: when the stimulus is 3 seconds, by step 3.3) to obtain an identification of the target f-target (0), and stimulation of the user gaze target to form an indicator, referring to FIG. 2, representative after Fourier transformation, the ratio of the sum of the amplitude value at the stimulation target frequency amplitude and all the target stimulation frequency, referred to as calculating the ratio value; dynamically adjusting on the basis of the obtained static result, sliding window is 3 seconds to 0.5 seconds is a sliding step length each time after 0.5 seconds overlapping sliding, re-judging whether the identification of the target f-target (m); m is the sliding times, average level of chance and re-calculating the size proportion value of the 4 classification problem represented by round chessboard is set as 25%, when the ratio value is more than 25%, it is considered that the ratio value has significance, and when the proportion value is no more than 25%. Referring to FIG. 2, the stimulation interface displaying real-time eye gaze position collected by the eye tracker, and through prompt tone indicating the user needs to concentrate attention).
As to claim 11, the claim is interpreted and rejected as to claim 1.
As to claim 12, the claim is interpreted and rejected as to claim 2.
As to claim 13, the claim is interpreted and rejected as to claim 3.
Allowable Subject Matter
5. Claims 4-5, 7, 14-15 and 17 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. However, an updated search will need to be performed after the next response from Applicant.
Claims 6, 10; 8-9; 16, 20; 18-19 are also objected to as being directly or indirectly dependent of claim 5, 7, 15 and 17 respectively.
Citation of pertinent Prior Arts
6. The prior art made of record and not relied upon is considered pertinent to applicant's disclosure: see PTO-892 Notice of References Cited.
