| Popis: | Household appliances are becoming more varied. In daily life, people usually refer to printed documents while they learn to use different devices. However, augmented reality (AR) assistive systems providing visual and aural instructions have been proposed as an alternative solution. In this work, we evaluated users’ performance of instruction understanding in four different ways: (1) Baseline paper instructions, (2) Visual instructions based on head mounted displays (HMDs), (3) Visual instructions based on computer monitor, (4) Aural instructions. In a Wizard of Oz study, we found that, for the task of making espresso coffee, the helpfulness of visual and aural instructions depends on task complexity. Providing visual instructions is a better way of showing operation details, while aural instructions are suitable for presenting intention of operation. With the same visual instructions on displays, due to the limitation of hardware, the HMD-users complete the task in the longest duration and bear the heaviest perceived cognitive load. |
