The interactive doorknob gives hints for participant's actions. When the participant
comes closer to the VR door (Fig. 2c) and is too big to fit through, the doorknob says:
“Sorry! You're way too big.”
When the participant approaches the door and has no
key with her, the doorknob says:
“No use. Haha! I forgot to tell you. I'm locked.”
If
the participant approaches the door and has the key in her hand, the virtual door will
open. If the VR door opens the participant sees the White Rabbit in a beautiful garden
waving and saying:
“Oh, dear! Oh, dear! You will be late”
(Fig. 2d).
A narrator voice gives guidance based on the participant's behavior. As the
participant moves around in the environment, the number of triggered pressure
sensors is counted. When the number of steps passes eight the narrator voice says:
“Are you just moving around in here, will you ever find the way out?”
If standing on
the same position is detected the narrator voice says;
“Oh dear! You are just standing
here!”
To facilitate the progress through the story, we introduced explicit feed-
forward hints from the interactive doorknob, like
“Alright, try the bottle”, “Now try
the box on the table”
. After three minutes, the doorknob gives the appropriate
guidance, depending on the last taken action from the participant and waits for the
participant to finish it.
