Feedback from the
company
Verified Narrative
“The experience with non-collocated project
members and the collaborative design and
feedback process in the virtual reality
environment shows potential for KOMPAN. We
develop playgrounds and fitness equipment
structures in Berlin and Brno. The designers at
those places need to communicate and
collaborate on the design and development of
structures that are complicated. I see potential
in working on similar scenarios in the company.
In this project, the industry-academia
collaboration would have benefited through the
product development if we had involved a more
complicated playground structure of an
ongoing project. […]”
Yu & Khalid (2019)
After the first VR presentation, the company
stakeholders asked for a step by step guideline
on how to create a shared VR environment and
how to import 3D models into it.

The selection and installation of VR systems at two locations, 2. collaborating with external organization, 3. facilitating the course activities for students to learn VR systems and to work on the problem and scope in collaboration with the external organization, and 4. facilitating the VR-mediated collaborative prototyping and feedback activities with the stakeholders of the external organization.

Department of Sports Science and Clinical Biomechanics sdu.dk#sdudk November 2019 VR-Integrated Prototyping: Decisions by Groups No group adopted MasterpieceVR for co- creating the surroundings. Defective – only the person importing can see, no redo, and cannot save the co-created object. Two groups used SculptrVr to draw surroundings. The third group chose Blocks by Google. The students argued that Block has a better user interface and features for designing the objects. Exported OBJ files are imported to Sketchbox for presentation.

- 17. sdu.dk#sdudk November 2019 Department of Sports Science and Clinical Biomechanics Students’ reflections on VR systems learning experience Questions Asked What are the VR tools used during the whole process? What are the features used to create the surroundings? Why? Describe the development process briefly. How long time did you spend on learning/experiencing the tools? How long time did you spend on creating the surroundings? Will you use VR for other projects? If yes, what will be the purpose? And Why? Pros VR technology shows great potential in the early phase product design. It is easy to learn these VR sculpting and painting tools. It creates a design space with a realistic sensation, and unlimited space and materials for mockup, which is ideal for creativity. The multi-user access feature supports collaborative design and creation. It is useful for quick mock-up and prototyping. VR technology provides useful tools for demonstration and feedback. The design object can be presented intuitively. It can show both the overview of the concept or the detail of an object. It links people into the same shared virtual space. There is a benefit of saving on time and cost for e.g. travel and other running costs Yu & Khalid (2019)

How long time did you spend on creating the surroundings? Will you use VR for other projects? If yes, what will be the purpose? And Why? Cons The sculpting software is still in the early development phase (modelling). The drawings created by these VR tools are too cartoonish. The currently available VR tools are not designed for technical drawing and 3D modelling, i.e. missing engineering-oriented functions. The current VR headset is still not as comfortable as a wearable device. It is too big for head-wearing and it creates dizzy feelings Technical issues The VR system adopted for communication is not very reliable with multiple users. Sketchbox crashed a few times when the students present the design objects, mostly during the loading phase. The size of design object, being imported the virtual environment, is dependent on the minimum computer power of all PCs’ being connected. Yu & Khalid (2019)

How long time did you spend on creating the surroundings? Will you use VR for other projects? If yes, what will be the purpose? And Why? Time spent for learning Per student, 15 to 20 hours for self-learning of the VR tools, and then two to four hours for creating the surroundings. Two hours introduction lecture, one hour presentation and feedback, 20-27 hours per group in VR. Future interest for collaborative use of VR The questionnaire results indicate that 13 out of 14 students decided to use VR in their future projects. The use of VR will be mainly for communication purpose, i.e. demonstrate the design object in VR to present the concept for feedback or stimulate new ideas or transfer knowledge. One student, who will not use VR in the near future projects, thinks that the technology is not ready for product design, and other modelling and prototyping methods are much easier.

- 21. sdu.dk#sdudk November 2019 Department of Sports Science and Clinical Biomechanics Conclusion and Scope of Future Work This pilot study explored the existing VR hardware and software for collaborative design and prototyping by non-collocated members of design teams and presenting the prototypes to the external organization as the client for the product requirement. A senior manager of KOMPAN fitness institute played the role of a client and provided authentic learning (Lombardi, 2007) opportunity for the students’ projects. SculptrVR and Google Blocks were used to co-create the surroundings and Sketchbox was used to import the models and remote presentation. From the health perspective, guidelines should be developed to inform the reasons behind experiencing dizzy feelings, protocols for troubleshooting and maximum duration of VR-based activities should be specified. Future research: Students with heterogeneous backgrounds (i.e. not engineering only) to work collaboratively. Assumption: Need for greater lab/technological support and peer-group learning.
