“…Thus, we instead live stream the smartphone screen over a Wi-Fi network. Previous research used the TCP protocol to send screenshots from a smartphone to a VR headset for visualization [3]. To reduce the latency further, we decided to use the relatively novel WebRTC protocol for screen streaming.…”

“…We decided to use the Unity game engine and Android Studio IDE for the prototype development, as they are free for personal usage and are standard development tools for VR and Android applications [3,22,39,60,88]. The prototype supports Android OS only for the purpose of installation simplicity.…”

“…We first tried to send screenshots of the smartphone via pure UDP packets and compared them to WebRTC performance. The WebRTC protocol with Android screencapturing features greatly outperformed screenshots and the UDP method which was used in another study [3]. WebRTC protocol requires a signaling server to establish communication between endpoints.…”

“…There are several studies examining the use of smartphones or wearable devices as VR input devices [3,13,87,34,39,47,48,51,53,71,80]. To date, none was able to track the smartphone's position and orientation with off-the-shelf VR headsets without attaching a bulky VR controller or tracking device to it.…”

Selection Performance Using a Smartphone in VR with Redirected Input

We present a method to track a smartphone in VR using a fiducial marker displayed on the screen. Using WebRTC transmission protocol, we capture input on the smartphone touchscreen as well as the screen contents, copying them to a virtual representation in VR. We present two Fitts' law experiments assessing the performance of selecting targets displayed on the virtual smartphone screen using this method. The first compares direct vs. indirect input (i.e., virtual smartphone co-located with the physical smartphone, or not), and reveals there is no significant difference in performance due to input indirection. The second experiment assesses the influence of input scaling, i.e., decoupling the virtual cursor from the actual finger position on the smartphone screen so as to provide a larger virtual tactile surface. Results indicate a small effect for extreme scale factors. We discuss implications for the use of smartphones as input devices in VR.
