How to Notify Team Members during Asynchronous Remote Collaboration supported by Mixed Reality: Comparing Visual, Audio and Tactile Notifications
Bernardo Marques, Carlos Manuel dos Santos Ferreira, Samuel Silva, Paulo Dias, Beatriz Sousa Santos · 2023
Solutions exploring Mixed Reality (MR) have been applied to remote scenarios, allowing to create a common ground. Literature reports that most studies focus on synchronous scenarios (team members interact in real-time). Therefore, an opportunity exists for asynchronous situations, in which collaborative actions occur at different moments and in which content is created/shared for later consumption. Hence, team members require notification methods to call their attention when new content is available. This work explored three notification cues: visual; audio; tactile, to comprehend which one captures the attention of team members easily. A user study was conducted with 26 participants to evaluate these conditions during asynchronous remote maintenance. The study was divided into two parts, focusing on the remote and on-site roles, given that both require methods to enhance their awareness. We report the results obtained, suggesting tactile cues represent the predominant condition for both roles.
