Text selection is a common task while reading a PDF file or browsing the web. Efficient text selection techniques exist on desktops and touch devices, but are still under-explored for Augmented Reality Head Mounted Display (AR-HMD). Performing text selection in AR commonly uses hand-tracking, voice commands, and eye/head-gaze, which are cumbersome and lack precision. In this poster paper, we explore the use of a smartphone as an input device to support text selection in AR-HMD because of its availability, familiarity, and social acceptability. As an initial attempt, we propose four eyes-free, uni-manual text selection techniques for AR-HMD, all using a smartphone - continuous touch, discrete touch, spatial movement, and raycasting.
