Extending the Body for Interaction with Reality

Research output: Contribution to book/anthology/report/proceedingArticle in proceedingsResearchpeer-review



In this paper, we explore how users can control remote devices
with a virtual long arm, while preserving the perception
that the artificial arm is actually part of their own body. Instead
of using pointing, speech, or a remote control, the users’
arm is extended in augmented reality, allowing access to devices
that are out of reach. Thus, we allow users to directly
manipulate real-world objects from a distance using their bare
hands. A core difficulty we focus on is how to maintain ownership
for the unnaturally long virtual arm, which is the strong
feeling that one’s limbs are actually part of the own body.
Fortunately, what the human brain experiences as being part
of the own body is very malleable and we find that during
interaction the user’s virtual arm can be stretched to more
than twice its real length, without breaking the user’s sense
of ownership for the virtual limb.
