Abstract:
An improved visual field perimeter testing tool is provided that employs a head mounted display apparatus configured to removably support a hand-held electronic device comprising at least one processor, memory system and integral display screen. The memory system stores a software program executed by the at least one processor, wherein execution of the software program carries out visual field perimeter testing of a subject wearing the head-mounted display apparatus whereby discrete stimuli are presented to the subject on the display screen of the hand-held electronic device. In order to address nonlinearity of the display characteristics of the hand-held electronic device, a calibration routine can be performed to generate calibration data that is stored as part of the software program and used to generate the RGB pixel values for the discrete stimuli and background that surrounds the discrete stimuli in a manner that provides accurate contrast sensitivity measurements during the testing.

Claim (Index 11):
A visual field perimeter testing tool according to  claim 9 , wherein:\n the memory system stores third calibration data that is used during the execution of the software program to determine a gamma correction factor; the resulting gamma correction factor is used during the execution of the software program to convert at least one RGB value in a corrected RGB color space for maximum luminance of the discrete stimuli or parts thereof to a corresponding RGB value in an uncorrected RGB color space; the resulting gamma correction factor is used during the execution of the software program to convert at least one RGB value in a corrected RGB color space for luminance of background that surrounds the discrete stimuli to a corresponding RGB value in the uncorrected RGB color space; the execution of the program constructs RGB pixel values in the uncorrected RGB color space for the discrete stimuli from the at least one RGB value for maximum luminance of the discrete stimuli or parts thereof and the at least one RGB value for luminance of the background in the uncorrected RGB color space; the execution of the program converts or transforms the RGB pixel values in the uncorrected RGB color space for the discrete stimuli to RGB pixel values in the corrected RGB color space for the discrete stimuli for display using the gamma correction factor; wherein the corrected RGB color space accounts for nonlinearity in the display characteristics of the display screen for the model smartphone that is executing the software program; and wherein the corrected RGB color space does not account for nonlinearity in the display characteristics of the display screen for the model smartphone that is executing the software program.
