ITI researchers present study on precise number input in virtual reality at VRST 2025

ITI researchers Pedro Miguel Matono, Ivo Roupa, Pedro Campos, and Daniel Simões Lopes presented the paper Assessing Redundant Interface Designs for Precise Number Input in Virtual Reality at VRST 2025, the 31st ACM Symposium on Virtual Reality Software and Technology, held in Montreal, Canada, from 12–14 November 2025.

The paper addresses the challenge of typing and editing decimal numbers in Virtual and Extended Reality environments. While numerical input is an important task in spatial computing, many existing tools rely on virtual replicas of physical calculators or number pads. To address this, the authors redesigned the traditional calculator-style numpad for Extended Reality environments, introducing redundant interface features intended to make number entry and editing easier, clearer, and faster than a standard numpad.

The study evaluated these redesigned interfaces through user testing. In testing, users preferred the redesigned interfaces compared to a standard numpad, reporting that the added features supported easier and more efficient entry and editing of numbers.

The paper was published in the Proceedings of the 2025 31st ACM Symposium on Virtual Reality Software and Technology (VRST ’25), Article No. 31, pages 1–12.
