In OPI: Open Perimetry Interface

Present static on Kowa AP7000 (internal use)

Description

Implementation of opiPresent for the Kowa AP7000 machine. Version for opiStaticStimulus.

This is for internal use only. Use opiPresent() with stim as class opiStaticStimulus and you will get the Value back.

Arguments

stim	Stimulus to present (a list, see details).
nextStim	The stimulus to present after stim (it is not presented, but projector can move to it during response window)

Details

stim is a list containing at least the following 3 elements:

• x, x-coordinate in degrees (floating point) (range $[-80,80]$).

• y, y-coordinate in degrees (floating point) (range $[-70,65]$).

• level is luminance in cd/\mbox{m}^2, and is rounded to the nearest whole dB for display (range 0 to 50). 0dB is 10000aps.

• duration of stimulus on in milliseconds (range $[100, 1200]$).

• responseWindow from start of stimulus presentation in milliseconds (max 5000).

• size one of .opi_env$KowaAP7000$SIZES_DEGREES.

• color one of .opi_env$KowaAP7000$COLOR_WHITE, .opi_env$KowaAP7000$COLOR_GREEN, .opi_env$KowaAP7000$COLOR_BLUE, or .opi_env$KowaAP7000$COLOR_RED

Value

A list containing

• err String message or NULL for no error.

• seen 1 if seen, 0 otherwise.

• time Reaction time (if seen).

• pupilX

• pupilY

• purkinjeX

• purkinjeY
