Step-by-Step Derivation:
- Normalize Inputs: Each raw input value is converted into a score between 0 and 100.
- Speech Recognition Accuracy (SRA): Directly used as a percentage. `SRA_Score = SRA_Input`
- Speech Output Clarity (SOC): A 1-5 scale is converted to 0-100. `SOC_Score = ((SOC_Input – 1) / 4) * 100`
- Calculation Speed (CS): Lower milliseconds are better. We invert this. Assuming a range of 50ms (best) to 1000ms (worst). `CS_Score = (1 – (CS_Input – 50) / 950) * 100`
- Number of Supported Functions (NSF): More functions are better. Assuming a range of 10 (min) to 100 (max). `NSF_Score = ((NSF_Input – 10) / 90) * 100`
- Battery Usage (BU): Lower mAh/hour is better. We invert this. Assuming a range of 50mAh/hour (best) to 500mAh/hour (worst). `BU_Score = (1 – (BU_Input – 50) / 450) * 100`
- Calculate Component Scores:
- Speech Interaction Score (SIS): This reflects the quality of voice input and output.
SIS = (SRA_Score * 0.6) + (SOC_Score * 0.4) - Processing Efficiency Score (PES): This measures how quickly the app performs calculations.
PES = CS_Score - Feature Richness Score (FRS): This indicates the breadth of mathematical capabilities.
FRS = NSF_Score - Resource Optimization Score (ROS): This assesses the app’s power efficiency.
ROS = BU_Score
- Speech Interaction Score (SIS): This reflects the quality of voice input and output.
- Calculate Overall App Performance Score (OAPS): A weighted average of the component scores.
OAPS = (SIS * 0.35) + (PES * 0.25) + (FRS * 0.20) + (ROS * 0.20)
