探索現實世界步行環境中虛擬會議的擴增實境介面設計

Abstract

過去的研究發現會議期間步行可以提升創造力、記憶力、注意力、健康和幸福感。儘管行動裝置的進步讓人們在虛擬會議期間不必限制在某一位置，但使用手機存在多種挑戰，例如由於螢幕小而導致的生產力下降和安全問題。在本文中，我們首次探索了在真實世界步行條件下虛擬會議的擴增實境(AR)界面設計。我們讓16位UI和AR設計師在現實世界街道上進行了步行線上會議並設計其界面，共有2x2的實驗狀況：在兩種不同交通複雜度與兩種不同會議形式下進行步行會議。結果顯示，設計的AR窗口平均觀看大小是最受歡迎的智慧手機螢幕的14.5倍。我們發現交通複雜度顯著影響了視窗的大小、透明度、位置和行為模式的偏好，而會議形式顯著影響了視窗的大小和透明度。此外，透過聚類分析(clustering analysis)總結出兩種常見的設計，這些設計可以作為未來研究的初步參考設計。

Research has shown that walking during meetings improves creativity, memory, attention, health, and happiness. While mobile technologies have freed users from having to be stationary during virtual meetings, mobile phones pose several usability challenges, such as reduced productivity due to small screens and safety concerns. In this paper, we present the first exploration of augmented reality (AR) interface design for virtual meetings in real-world walking conditions. We conducted design sessions in-situ with 16 user interface and AR designers using a 2x2 experimental design: meeting while walking in two levels of traffic conditions and with two types of meeting formats. Results show that the designed AR windows averaged 14.5 times in viewing size compared to the most popular smartphone screens. Also, Traffic Level significantly affected the size, opacity, and placement of windows, as well as the preference of anchoring modes, while Meeting Format significantly affected size and opacity. Furthermore, clustering analysis identified two groups of designs that can serve as initial reference designs for further customization and research.
