Abstract: One of the fascinating features of virtual reality is the ability for users to interact with objects just like in the real world. However, such interactions are limited to the reachable space. We propose a system called “Poros” that allows users to rearrange space. After marking a part of the space, the marked space far away is projected onto a nearby proxy. This enables users to freely arrange space within reach and easily interact with multiple distant spaces or nearby objects. The proxy becomes part of the scene and can be moved, rotated, resized, or attached to other objects. Moreover, it can be used for more advanced interactions like alignment or action duplication. We demonstrate how Poros enables various tasks and applications and validate its effectiveness through expert evaluation.

  • Locomotion + Interaction
    • Could be expensive
  • Extending the virtual body
    • Reaching out with hands
  • Shrinking space

Close Reading Introduction:

  • Explains why teleportation or ray casting may not be suitable.
  • In Poros, several methods enhance the miniature world, enabling users to (1) create instances remotely as needed, (2) manipulate boundaries, orientations, and positions of existing miniature worlds in the scene, (3) fix and make miniature worlds dynamic within the scene or objects, (4) integrate or split miniature worlds to duplicate space or actions, (5) perform operations like alignment or search on the miniature world, and (6) gradually peek into the miniature world and control how much of the view it occupies.

Implementation:

  • They use the Fresnel effect for shading to further emphasize the intersection points with the scene.
  • If a book falls in another room, the user normally wouldn’t hear it. However, if the book hits the ground within a marked space with a nearby proxy, the sound is reproduced at the corresponding location in the proxy space. Only sounds occurring within the marked space are audible through the proxy.
  • Interesting from the perspective of sound (blu3mo)
  • Or rather, this is the Ope Ope no Mi.

Applications:

  • When manipulating objects, viewing from a single perspective can hide important details and limit interactions. To aid this, many VR painting and modeling applications allow changing perspectives for easier drawing or manipulation of objects.
  • Some tasks require repetition, like filling multiple pet bowls or opening all windows in a room. To facilitate such tasks, Poros allows for interaction duplication. After merging proxies, one proxy space connects to multiple marked spaces, thus duplicating user actions between them. image
