An Initial Exploration of Visual Cues in Head-Mounted Display Augmented Reality for Book Searching

Paper in proceeding, 2022

Augmented reality (AR) is today becoming more widely utilized as it allows for interacting with the virtual objects. In this study, we propose an head-mounted display (HMD) AR system supporting book searching with visual cues. The visual cue is represented as a light-green blob hinting users for task completion, which significantly strengthens the overall performance. The system is implemented by using Microsoft HoloLens 2. The proof-of-concept version of the proposed solution is demonstrated in a pilot user study (n=8) comprising an experimental group (with visual cues, n=4) and a control group (without visual cues, n=4), followed by quantitative analysis of task completion time (TCT) and NASA task load index (TLX). The results show that our proposed HMD AR solution improved the task performance and had cognitive benefits for book searching tasks.
