In exhibition settings such as art galleries or museums, Augmented Reality (AR) has the potential to provide detailed information about exhibits. While most existing systems provide only general information overlaid on top of the arts, our AR guide system aims to explain multi-section detailed information hidden in the painting. In this paper, we present the design and implementation of our AR guide system in the Microsoft HoloLens and 5 guiding interfaces: Audio, Arrow, Circle, Arrow-Move, and Circle-Move that point out a specific part of the exhibit and explain the detailed information. We also included an embodied agent (EA) as a virtual guide to help engage the user when explaining the detailed information. We conducted a user experiment that simulates guidance for a large painting to evaluate user experiences with and without the EA condition for these interfaces. Results showed that guidance from the EA significantly increased either attractiveness, stimulation, or novelty for the system.
