We expanded on previous research<\/a> and conducted a study comparing AMP-IT and WISDOM during alignment of objects with complex geometry to evaluate the potential influence of geometric complexity on the performance, usability, workload and preference. Our findings indicate that participants had faster completion times and higher trial completion rates with AMP-IT on high-precision alignment tasks, contrary to earlier findings that used simple objects. Yet WISDOM is still preferred and considered more usable, despite increased workload and poorer performance, exposing participants\u2019 willingness to trade objective performance for comfort during use. This work has be accepted to IEEE VR 2026.<\/p>\n\n\n\n

Participant\u2019s view during the alignment task. The manipulation object is the opaque, white lattice structure. The target is the translucent, black object. The manipulation object turns green on valid alignment within the target object. (A&B): The AMP-IT interaction technique. (C&D): The WISDOM interaction technique.<\/em><\/p>\n\n\n\n

My expertise area is Virtual and Augmented Reality within the scope of 3D User Interfaces. Some specific research interests include how to use augmented reality for improving productivity on real-world tasks (such as working with virtual monitors and how to design cross-device interaction), and how to enhance the process of content creation through immersive technologies (such as architecture design and visualization).<\/p>"},{"term_id":501,"user_id":0,"is_guest":1,"slug":"francielly","display_name":"Francielly (Elly) Rodrigues","avatar_url":{"url":"https:\/\/wordpress.cs.vt.edu\/3digroup\/wp-content\/uploads\/sites\/141\/2025\/10\/D9E7D095-A562-459F-A5D2-77F36EE71D1C-scaled.jpeg","url2x":"https:\/\/wordpress.cs.vt.edu\/3digroup\/wp-content\/uploads\/sites\/141\/2025\/10\/D9E7D095-A562-459F-A5D2-77F36EE71D1C-scaled.jpeg"},"author_category":"1","user_url":"https:\/\/www.linkedin.com\/in\/franciellyrodrigues","last_name":"Rodrigues","first_name":"Francielly (Elly)","job_title":"Presidential Postdoctoral Fellow","description":"Francielly (Elly) Rodrigues is a Presidential Postdoctoral Fellow in the Department of Computer Science at Virginia Tech\u2019s College of Engineering.

Her interests center on context-aware and intelligent Extended Reality (iXR) systems, particularly how immersive interfaces can sense contextual information about the user, task, and environment, reason over it, and adapt accordingly. This adaptability is essential for XR to be practical and effective in everyday life.
