Evaluation of 3D Selection Tasks in Parabolic Flight Conditions: Pointing Task in Augmented Reality User Interfaces (3DPICK)
Study Overview
Detailed Description
Investigations description --------------------------------- Augmented Reality 2 different Head-Mounted-Displays (ARVision3D from Trivisio; dataGlass/2A from Shimadzu), controlled by 2 PC will be used. The first HMD is a monocular optical see-through (OST) HMD: it is equipped with a semi-transparent LCD display for one eye. The user can directly see the physical world without limitations regarding the peripheral field of view. The second HMD is a binocular video see-through (VST) HMD: it is equipped with two LCD displays and a stereo camera system that records the physical environment and replays the video onto the displays in real-time.
Experimental protocol
---------------------------- Before flight subjects will be familiarized with the setup and the protocol. For each flight day, 2 subjects will be studied one for each AR device. Halfway during the flight, the 2 subjects will swap places. The procedure will be the following on all 3 days.
The experiment day will start at 7.30 a.m. with the test subjects equipped with heart rate recording device. After take-off and after work will be permitted, the 2 subjects will go to the experimental area where they will be seated. They will be equipped with one of the HMD (optical- or video-see through HM). During a parabola the subjects perform the experimentation task: symbolic input of five letters onto virtual keyboard depending on the experimental task during a parabola.
To point towards the virtual keyboard the subject wears a thimble on his forefinger. The body-alignment scenario requires an additional panel on subject's non-dominant hand.
During a parabola two subjects perform the tasks - one is using HMD type 1 in hyper-g and the other subject is using HMD type 2 in micro-g.
During the 8 minute rest period between parabolas 15 and 16, the 2 test subjects will switch places. Switching place will be a straightforward process as each member of our team has expertise in manning the test equipment.
