From: Niels Hilbrink Subject: TECH: HUMAN-FACTORS: measure for presence: Questionnaires Date: Mon, 25 Nov 1996 13:55:10 +0100 Organization: National Aerospace Laboratory Hi, I doing my master thesis on the subject of virtual environment based training for cosmonauts. One of the tasks is to evaluate performance in an environment with a varying number of cues. So after reading a number of article on the theoretical way to measure presence (Zeltzer, Sheridan, Ellis, master-thesis by Keith Hullfish, etc) I figured I was ready to actually do some experiments. Right, so I go my hands on the Immersive Tendencies Questionnaire (ITQ) and Presence Questionnaire (PQ) created by Witmer & Singer. But they use four discriminating categories: Control, Sensory, Distraction, and Realism factors. Not three like Zeltzer and Sheridan. My questions: 0 Can anybody explain to me how to convert this four category scale into either the Zeltzer or Sheridan model ? 0 Does anybody know of other measures for performance in virtual environments, especially questionnaires based on either Zeltzer or Sheridan ? (My performacne parameters are, time to completion, accuracy and the level of simulation sickness). 0 Has anybody got some HARD data on tests. (rather than vague answers and maybes) Best Regards, Niels Hilbrink -- ======================================================================== | I didn't really say all the things that I said.
