Intergraph Smart 3D Model Manipulations

Design Challenge
While manipulating a 3D model orientation, the disconnect between view orientation of the model, in relation to the direction that a user tried to manipulate the model was excessively frustrating.

Understanding user goals and challenges
During contextual inquiries with end users, we were able to see exactly how and where they struggled. View cube (static image) did not change its orientation based on changes in model orientation. Also, the availability of just one view cube for multiple graphic windows led to user frustrations. Based on observations, we then worked on capturing opportunities for improving the navigation experience. To further assist our design process, we sketched two user stories to help us understand end user scenarios better.

Sketching possible solutions
Based on data from user research, we sketched six to seven possible solutions.
View Manipulation SketchesPrototype and test two designs
We selected two good ideas to prototype, based on the design challenge. A/B tests of the design prototypes helped us iteratively improve design concepts. Results helped us explore how users perceived the new controls basic functionality; how did a users’ previous experience play a role in drawing inferences on using the new control; and what functions were walk up and use and which required additional help.

High-stakes project – everyone wanted a say in the design!
Need for high fidelity prototypes vs. project deadlines

An immersive mode of embedding the 3D model in a cube when needed, with additional easy to use hotspots on edges and corners of the cube was the final solution.

We observed, 44% decrease in error rates and 31% improvement in completion times when users reoriented the 3D model in standard perspectives with the new design.
