ABSTRACT
With recent advances in augmented reality (AR) and computer vision it has become possible to magnify objects in real time in a user’s field of view. AR object magnification can have different purposes, such as enhancing human visual capabilities with the BigHead technique, which works by up-scaling human heads to communicate important facial cues over longer distances. For this purpose, we created a prototype with a 4K camera mounted on a HoloLens 2. In this demo, we present the BigHead technique and proof of concept AR testbed to magnify heads in real-time. Further, we describe how hand gestures are detected to control the scale and position of the magnified head. We discuss the technique and implementation, and propose future research directions.

Intuitive User Interfaces for Real-Time Magnification in Augmented Reality
VRST '23: Proceedings of the 29th ACM Symposium on Virtual Reality Software and TechnologyVarious reasons exist why humans desire to magnify portions of our visually perceived surroundings, e.g., because they are too far away or too small to see with the naked eye. Different technologies are used to facilitate magnification, from telescopes ...

ASSETS '18: Proceedings of the 20th International ACM SIGACCESS Conference on Computers and AccessibilityAugmented reality (AR) systems that enhance visual capabilities could make text and other fine details more accessible for low vision users, improving independence and quality of life. Prior work has begun to investigate the potential of assistive AR, ...
Multimodal augmented reality: the norm rather than the exception
MVAR '16: Proceedings of the 2016 workshop on Multimodal Virtual and Augmented RealityAugmented reality (AR) is commonly seen as a technology that overlays virtual imagery onto a participant's view of the world. In line with this, most AR research is focused on what we see. In this paper, we challenge this focus on vision and make a case ...
