Abstract

The consumption of 360-degree videos with head-mounted displays (HMDs) is increasing rapidly. A large number of HMD users watch 360-degree videos at home, often on non-swivel seats; however videos are frequently designed to require the user to turn around. This work explores how the difference in users’ chair type might influence their viewing experience. A between-subject experiment was conducted with 41 participants. Three chair conditions were used: fixed, half-swivel and full-swivel. A variety of measures were explored using eye-tracking, questionnaires, tasks and semi-structured interviews. Results suggest that the fixed and half-swivel chairs discouraged exploration for certain videos compared with the full-swivel chair. Additionally, participants in the fixed chair had worse spatial awareness and greater concern about missing something for certain video than those in the full-swivel chair. No significant differences were found in terms of incidental memory, general engagement and simulator sickness among the three chair conditions. Furthermore, thematic analysis of post-experiment interviews revealed four themes regarding the restrictive chairs: physical discomfort, difficulty following moving objects, reduced orientation and guided attention. Based on the findings, practical implications, limitations and future work are discussed.
