Hololens:Visualization beyound two dimensional displays

Together with our partners from the finance sector, Techruption, and the campus, we have developed and evaluated several novel visualization approaches to help portfolio managers oversee assets while more efficiently considering carbon emissions. Our study systematically investigates the differences in user perception between a regular monitor and a mixed reality device.
We conducted a real-life, within-subject experiment in the field with twenty-eight investment bankers, assessing both subjective and objective task performance across two-dimensional and three-dimensional systems. The experiment tested accuracy with regard to position, size, and color using both single and combined tasks.
Interestingly, our results did not show a significant difference in accuracy between mixed-reality and standard 2D monitor visualizations. This finding has important implications for the development of financial visualization tools, suggesting that the choice between 2D and mixed reality interfaces should be driven by factors beyond mere accuracy, such as user preference, implementation costs, and specific use case requirements.
