Abstract
Multimodal feedback is used to convey various and rich information
in virtual environments. It can also change users’ perceptions
of the haptic properties of objects through the pseudo-haptic illusion.
While visual feedback has been extensively examined to
induce haptic properties like weight in virtual reality, only a handful
of studies have explored the use of audio feedback, and even
fewer in augmented reality. Our study aims to extend, in an augmented
reality context, previous research findings that used sound
to enhance the weight perception of virtual objects. Participants
were asked to grab two objects that produced sounds with different
audio delays and brightness and to determine which of the two
was heavier. The results on 38 participants showed that while the
delay did not affect weight perception, the brightness did have a
significant impact. This is in line with previous studies and could
be used to enhance the perception of hand interactions in AR.
