chooseOpi {OPI} | R Documentation |
Choose an implementation of the OPI
Description
Chooses an implementation of the OPI to use
Usage
chooseOpi(opiImplementation)
chooseOPI(opiImplementation)
Arguments
opiImplementation |
A character string that is one of the following.
-
"SimNo" for a simulator that always doesn't see.
-
"SimYes" for a simulator that always does see.
-
"SimHenson" for a simulator that uses a cummulative gaussian psychometric function with standard deviation according to Henson et al (2000) where variability increases as true threshold (Humphrey dB) value decreases.
-
"SimHensonRT" as for SimHenson, but response times in ms are sampled from a supplied response time data set for each true positive response.
-
"SimGaussian" for a simulator that uses a cummulative gaussian psychometric function with standard deviation supplied in opiInitialize().
-
"Octopus900" for interfacing with the Octopus 900.
-
"Octopus900F310" for interfacing with the Octopus 900 using Logitech F310 controller.
-
"Octopus600" for interfacing with the Octopus 600.
-
"HEP" not working so well in HEPs.
-
"KowaAP7000" for interfacing with Kowa AP-7000.
-
"Imo" for interfacing with CrewT's Imo head mounted perimeter.
-
"DayDream" for interfacing with an Android phone in a Google Daydream
-
"Display" for interfacing with a shiny plot area on the current machine.
-
"PhoneHMD" for interfacing with phones using VR. At the moment, only Android compatible phones are working. The VR headset must be compatible with Cardboard
-
NULL print a list of available OPI implementations.

Value
Returns TRUE if successful, FALSE otherwise.
