Summary

Our need finding composes of two aspects. (1) Survey people on the current system to find out what usability problems exist and what they would like to see changed. (2) Interview experts in the field who could also be users of this system to learn important details about how to design the system

Survey

We created a survey and had people test out the system and then fill out the survey. We also had our domain experts go through this process since they are also potential users of the system.

Survey Questions

Results

Other feedback was mostly about things we are restricted on based on the holo lens. People found the device heavy, had trouble pinching and with the device recognizing their hand, and did not like gaze interaction.

Interviews

We interviewed domain experts from the optics field to learn about how optical designers may use a system like ours. This is very valuable information because we can make sure we are solving problems that actually exist and creating solutions that work well for the users.

Questions

Results

• There was a consensus that the optics field is not the most accepting of new technology and it would be hard to get people to take this seriously
• People agreed it could be a very powerful tool for education or visualization but there was a lot of hesitation for using it for designing
• There are a lot of very smart older people in the optics field who would not only be not accepting of this technology but also would just be unable to use it.
• Currently widely used systems are old and do have bugs that have just never been fixed.
• You can buy components from a catalog that are often used educationally in a similar way to this system
• Most struggled at first but once they got it they enjoyed the interaction.
• Would not use it for anything that required precision
• People did not like bimanual rotation but did like both bounding box and the widget.
• Widget was deemed more precise but some struggled with grabbing the widget
• Bounding box was liked but people did see it being a problem with having many lens close together
