Acquisition study for occluded interaction
Description
In this study, participants wore an AR headset and were asked to interact with objects occluded by a wall in front of them. They had to reach around to then manipulate the objects. They were supported in this task by several different kinds of visualization that showed them the object of interest. After each trial and at the end of the study, the participants provided ratings of each visualization as well as a ranking of the different visualizations.
Usage
OccludedInteraction
Format
A list with two entries:
participants with 6 fields for 24 study participants:
- user
Participant ID.
- age
Participant age.
- gender
Participants' self-reported gender.
- glasses
Whether the participant wears glasses.
- handedness
Participants' dominant hand.
- ar_experience
Self-reported level of experience with AR on a 5-point scale ("none" to "a lot").
ratings with 6 fields:
- user
Participant ID.
- block
Block ID. 99 is used to denote final questionnaire after the study.
- object
Occluded object that had to be used. Can be: button, dial, hdmi, hook, or slider.
- view
Visualization available during the trial. Can be: none, static, dynamic, cloned, or see-though.
- question
Which question was asked. Can be:
- liked overall
"Overall, I liked using the visualization when interacting with the object." ("Strongly disagree" to "Strongly agree")
- supported
"How well did the visualization support you during the task?" ("Strongly impeded me" to "Strongly supported me")
- manipulate
"I could easily manipulate the object." ("Strongly disagree" to "Strongly agree")
- check state
"I could easily check the state of the object." ("Strongly disagree" to "Strongly agree")
- ranking
"How would you rank the five visualization with respect to how easy/hard they made it to interact with the object?"
- rating
"Please rate each view for how well it overall supported you during the study." ("Strongly impeded me" to "Strongly supported me")
- rating
Value between 0 and 6 for all ratings and 0 to 4 for the rankings.
