Enquadramento
Virtual Reality (VR) is becoming increasingly relevant due to the availability of mainstream VR devices such as the HTC Vive, Oculus Rift, Google Cardboard, etc. As VR becomes increasingly available, users will need authoring systems that run inside the Virtual Environment (VE). Authoring software is created to support specific tasks and must do so efficiently. This requires studying interaction techniques and devices and choosing the most appropriate one for the given task.
In this project, we are interested in studying pointing/selecting and tracing tasks. Pointing/selecting and tracing tasks are fundamental in drawing software for example to perform object selections, or for painting over existing objects in a 2D image.
Objetivo
The objective of this work is threefold:
1. To implement a set of chosen interaction techniques for pointing/tracing tasks for VR. Although not mandatory it is also suggested that the student contributes these implementations as open-source software for the A-Frame open-source platform.
2. To evaluate a set of chosen techniques in immersive, i.e., Head Mounted Display (HMD)-based VR, comparing their performance
3. To characterize the 3D movement that users produce while using the chosen techniques (e.g., see [1, 4]
Although the student should start by reviewing existing techniques for pointing/selecting and tracing tasks, the following high-level approaches are suggested: gaze-based tracing (with supporting remote controller for starting/stopping), VR controller-based, Leap Motion based).
Plano de Trabalhos - Semestre 1
- Study VR interaction techniques and devices for pointing/selecting and tracing tasks
-- Deliver a related work chapter describing pointing/selecting and tracing tasks evaluations that have been made before for VR or non-VR settings
-- Study tracing tasks experiments (for this project we can try to follow the experiments made by [1-6]
- Select interaction techniques to implement and evaluate comparatively
- Implement at least one of the chosen techniques.
- Write intermediate report
Plano de Trabalhos - Semestre 2
- Implement the chosen techniques
- Implement the necessary software for data collection
- Perform a user evaluation and gather empirical data that compares the performance of users doing pointing/selecting and tracing tasks with the different techniques
- Write the results as a scientific publication and dissertation
Condições
Access to HTC Vive VR headset
