Background

Virtual Reality is not a new piece of technology and its existence has been around for a couple of decades. The current wave of VR today is attributed to the advancements of technology, making it relatively much cheaper and available to the masses. As such VR development and utilization is still in a very early stage, much is still being discussed and explored.

In this project, the goal was to find out more about the interaction of VR. Specifically what are the affordances and the implications of the different types of interaction and its relation to the user experience (UX) itself. This is a crucial first stage if VR is going to be utilized as a tool in areas such as research, education and training.

User Testing

Theory & connection to study

In VR there are 2 important factors that can determine if an experience is successful or not. The first is presence and the second is immersion. A designer and developer can design for immersion; however, presence is something that happens on the end of the user. There are multiple different nuances that can contribute to presence such as the user’s willing suspension of disbelief. In my research I have discovered some overlapping similarities between characteristics of presence and that of flow, which is from flow theory in psychology. (Mihaly Csikszentmihalyi) An illustration of flow theory can be seen from the diagram.

The test here is to utilize measurements in flow theory to see how it may relate to measuring presence in VR. As such this will give an insight to designers and developments what should be done when creating interaction in VR.


Study Design Plan

There are a total of 3 different modes of interaction that each user going through the test has to complete. In order to maintain proper unbiased data, a Latin square has been adopted to determine the sequence of each participant. This is randomly assigned to a participant in relation to their participant number.

VR Development

Sequence 12

The development of the VR environment went through multiple iterations. In its core, there were two specific interaction systems that needed to be included in the design. The first is the HTC Vive controllers and the second is the leapmotion hand tracking device. Each had a different level of interaction, engagement, control, precision and a learning curve. Here you see a clip of an early test of the hand tracking interaction.

Task & Environment (Physical & VR)

The environment between the physical world and virtual reality was designed to reflect each other. This will enable a fair test and creates a cognitive similarity for participants. The task sequence is as follows:

 1 Pick up ball from green area with primary hand

    and transfer to secondary hand

2 Place ball on blue area

3 Move ball without lifting to red dot

4 Pick up and toss ball into red box

Data capture & Sample

Sequence 03_1

Data captured for analysis included video recording, screen capture, observational notes, and a questionnaire that was designed based on flow and engagement. Here is a clip of one of the participants in the hand-tracking sequence. The sample of participants had no prior VR experience so the interaction was new for them.

Constant results from questionnaire showed that participants felt they were in most control in C which were the Vive controllers. It is interesting that the initial perceptions of participants were that the hand tracking was more easy and fun but after going through the task the limitations of the hardware led them to favor the controllers more.

Some of the takeaways from the study is that:

The preference for the Vive controllers is due to more control.

The dislike and break of flow and engagement of participants with hand tracking is due to uncanny valley.

Though hand-tracking was closer to realistic interaction, the use of controllers as hands became more natural after some time of concentrating on the task. This could be due to cognitive effects such as common coding theory.

This study led to another more specific pilot study on flow which can be downloaded here if you are interested in the findings.
