Circular: j-th of evaluation and test person is to N number of critical evaluation index XiAccording to from least care to most concerned about progress
Sequence, according to ranking results according to principle of equipartition, divides 10 units equally, i.e.,Each key is obtained to comment
The reference of valence index weights divides Score (Xij), wherein Score (Xij) represent jth position evaluation and test person and provide critical evaluation index XiPower
Reference point again.The weight of the critical evaluation index provided according to all measured is with reference to a point calculating critical evaluation index XiWeight
With reference to dividing mean value
WhereinRepresent critical evaluation index XiWeight with reference to dividing mean value.Above-mentioned mean value is normalized
Processing, obtains each critical evaluation index XiWeight coefficient
Wherein λiRepresent critical evaluation index XiWeight coefficient,Represent all critical evaluation indexs
Weight reference divides the maximum value of mean value,All critical evaluation index weights are represented with reference to the minimum of point mean value
Value.
Calculate the average mark of the critical evaluation index of virtual reality human-computer interaction system.According to scoring matrix Xij, utilize
Following mathematical model calculates marking result
Wherein XijJ-th of evaluation and test person is represented to XiThe marking of parameter is as a result, uiAll evaluation and test persons are represented to refer to key evaluation and test
Mark XiThe mean value of marking.
The user experience quality score value QoE for calculating virtual reality human-computer interaction system, according to the weight coefficient of step 4 and the
The marking of 5 steps is as a result, calculate QoE value using following formula.
In some illustrative embodiments, the user experience marking model in the S6 is beaten according to user's subjective experience
Divide and carry out machine learning, and export learning outcome, user experience marking model is established according to learning outcome.
In some illustrative embodiments, the accuracy in the S7 is verified in the form of confidence interval.
