Delta Data
-
diff_data: Numerical data representing touch panel sensor changes over time. -
Multiple numeric arrays represent the fluctuations, likely differences in the sensors' readings across several time points, or consecutive sensor measurements. Negative values suggest decreased pressure or movement away from the expected position. The dataset is relatively large, indicating a significant number of measurements.
Baseline Data
-
basline_data: Numerical data, likely representing the baseline sensor readings. Similar todiff_data, this array provides a potential reference point for touch input analysis. The raw values indicate precise sensor readings.
