This year, the IEEE 3DUI 2016 Symposium will hold the 7th annual 3DUI Contest. It is open to anyone interested in 3D User Interfaces (3DUIs), from researchers to students, enthusiasts, and professionals. The purpose of the contest is to stimulate innovative and creative solutions to challenging 3DUI problems. 3DUI 2016 will be co-located with IEEE Virtual Reality. Due to the recent explosion of affordable and portable 3D devices, this year's contest will be judged live at 3DUI. Contestants are required to bring their systems for live judging for attendees to experience them.


The 3DUI Contest is open to anyone interested in 3DUIs g- researchers, students, hobbyists, and professionals, or anyone else. Contestants can use any software and/or hardware to develop their solutions.

Problem Description

Build an innovative 3DUI for collaborative manipulation of objects in a virtual environment, which fulfills the following requirements:

The 1st requirement is that the newly developed user interface is a real 3DUI, which excludes “classic” interaction hardware such as keyboard and mouse; these may be used, but not as main interaction hardware. Virtual environments and display systems can be part of the solution but do not count as 3DUIs.

The 2nd requirement for the collaborative 3DUI is that it has to embed two or more users in applying the following three different manipulation operations to an object in a virtual environment: translation, rotation, and resizing.

The 3rd requirement is that the collaborative 3DUI has to benefit from the collaboration of two or more users applying one manipulation operation (translation OR rotation OR resizing) on one object together.

The 4th requirement is that the use of the 3DUI can be simply learned. During the on-site demo of the 3DUI, a trained (presenter) and one or more untrained (visitor) collaborators should be able to apply the collaborative operation to a given object in a given scene.

The 5th requirement is that the 3DUI enables users to apply (in the aforementioned manner) all three manipulations to a given scene (provided under “Materials” below). The task is a lifting job, where 3D objects have to be moved from an initial position to a goal position following a predefined path by overcoming various obstacles. This makes it necessary to rotate, resize and translate the objects accordingly. We encourage all participants to also offer their own scenes to highlight the specific features of the developed 3DUI or for training.

In summary, your proposed collaborative 3DUI should
... be constructed with a focus on an innovative 3DUI,
... be able to let the users apply three manipulation operations: translation, rotation, and resizing collaboratively (such that two or more users are active and synchronously involved),
... benefit from the collaboration of two or more users,
... be simple to learn and use, and
... be effective, able to apply all three manipulations to objects in the provided scene.

In addition to the live demo, contestants must submit a 90 second video and a two-page abstract, which describe how they developed, evaluated, and iterated upon their solution, and describes related previous work, and how their system is novel. The judging criteria are novelty, effectiveness, and usability (all equally weighted) of the interaction methods as well as the degree of fulfillment of the above-defined requirements. Specifically, the video should show solving the first two tasks provided in the scene under "Materials". More information can be found on the rules page.

Tasks & Materials

The tasks to be completed regarding requirement 5 (see above) are the following:

  1. A scaling+translation task:
  2. A rotation+translation task:
  3. A scaling+rotation+translation task:

The goal of the task is to transform the given cube to the other side of the wall by covering as big moving volume as possible. Thus, you must not scale down the size of the cube to a minimum to simplify the tasks. Please refer to the provided videos above. All tasks have to be completed by using the developed 3DUI. The model is available as Unity3D package online:
