Testing of Visual Field with Virtual Reality Goggles in Manual and Visual Grasp Modes
Figure 3
Example of luminance and dB calibration for OLED microdisplay. (a) Measured luminance versus video control level (gray level). Average luminance obtained in a series of 6 measurements performed over a period of 8 months with error bars representing the standard deviation. Solid red line is a cubic spline fit to the measured averaged data. (b) Stimulus intensity on the Humphrey decibel scale (dB) as a function of video level. Points represent dB values corresponding to consecutive integer video levels on 8-bit scale. Solid lines represent standard deviation associated with reproducibility of luminance measurements.
