Ph.D. student Felipe Bacim successfully completed and defended his dissertation work titled “Increasing Selection Accuracy and Speed through Progressive Refinement.” In this innovative research, Felipe designed and evaluated 3D selection techniques based on the concept of gradual refinement of the set of selectable objects, rather than single immediate selections. The work has been published in the IEEE Symposium on 3D User Interfaces and the International Journal of Human-Computer Studies, among others. Felipe will soon begin work at Apple, Inc.
