“…Gaze in turn is free to point anywhere within an HMD display but not able to point beyond. Prior work on AR pointing found techniques that are reliant on a cursor that moves with the viewport to be less performant than techniques that are decoupled from the viewport [10]. This contrasts with the finding of Cao et al where Fig.…”

Fig. 1: Our study task sequence to investigate the selection of dynamically revealed targets. A: To start the task, the participant has to search for a start target presented outside their field of view. B: Upon selection of the start target, a first target at an unknown position in the opposite direction, for the participant to select without prior knowledge. C: Upon selection of the first target, a second target is presented at the start position, for the participant to select with prior knowledge of target position. D: Selection of the second target completes the task.

“…Concerning XR S spaces, an additional criterion comes into play: the interaction technique should scale between HMDs and HHDs, i.e., the technique should remain intuitive to the users even when they switch devices. However, previous research has mostly focused individually on the various interaction modalities offered by XR technologies including in-air [45][46][47][48][49][50][51][52][53][54], touchbased [55][56][57][58][59], tangible [60][61][62], head-, gaze-, or speech-based [45,55,58,[63][64][65], and multimodal [55,58,64] input techniques to select and manipulate virtual objects as well as to navigate in space. Many of these approaches require tracking parts of the users' bodies or external interaction devices.…”

“…In these cases, inertial tracking is considered beneficial. Previous work (e.g., [56,58]) tracked the position and orientation of external input devices in space using device-incorporated IMU sensors-an inertial measurement unit that usually consists of accelerometers, gyroscopes, and magnetometers. Such approaches do not limit interaction to a particular part in space.…”

“…At the same time, the touch interface of the smartphone served as an input modality for further manipulations. Similarly, Chen et al [58] compared IMUbased interaction with smartphones and smartwatches acting as laser pointers. The cursor was hereby either controlled by the smart device only (i.e., the cursor could leave the field of view) or in a hybrid approach where the cursor always stayed within the field of view and large-scale movements could be performed by head movements and smallscale movements inside the current field of view with the smart device.…”

Extensive research has outlined the potential of augmented, mixed, and virtual reality applications. However, little attention has been paid to scalability enhancements fostering practical adoption. In this paper, we introduce the concept of scalable extended reality (XRS), i.e., spaces scaling between different displays and degrees of virtuality that can be entered by multiple, possibly distributed users. The development of such XRS spaces concerns several research fields. To provide bidirectional interaction and maintain consistency with the real environment, virtual reconstructions of physical scenes need to be segmented semantically and adapted dynamically. Moreover, scalable interaction techniques for selection, manipulation, and navigation as well as a world-stabilized rendering of 2D annotations in 3D space are needed to let users intuitively switch between handheld and head-mounted displays. Collaborative settings should further integrate access control and awareness cues indicating the collaborators’ locations and actions. While many of these topics were investigated by previous research, very few have considered their integration to enhance scalability. Addressing this gap, we review related previous research, list current barriers to the development of XRS spaces, and highlight dependencies between them.
