“…In the field of visual attention guidance, many different methods have been proposed in recent years for application in images as well as videos; in non‐immersive settings [DMGB04, BMSG09, VMFS11, HKS16], in VR settings using Head‐Mounted Display (HMD) [LCH*17, GSEM17, GAM18, RAK18, GTA*19], and even in an immersive room‐scale projection system [GATM18, GTA*19]. Attention guidance as a support means may be helpful in various application scenarios, such as virtual training or remote teaching [dKJ17, FMS*19, YKB19b, YKB19a], guided exploration [LH19], multi‐monitor surveillance tasks [SKB19] or immersive story telling [SP19, SRD*19, LSGB20]. For our survey on related work, we will distinguish between passive and active methods, that is, they do or do not actively incorporate real‐time gaze tracking data.…”

The peak of virtual reality offers new exciting possibilities for the creation of media content but also poses new challenges. Some areas of interest might be overlooked because the visual content fills up a large portion of viewers' visual field. Moreover, this content is available in 360° around the viewer, yielding locations completely out of sight, making, for example, recall or storytelling in cinematic Virtual Reality (VR) quite difficult. In this paper, we present an evaluation of Stereo Inverse Brightness Modulation for effective and subtle guidance of participants' attention while navigating dynamic virtual environments. The used technique exploits the binocular rivalry effect from human stereo vision and was previously shown to be effective in static environments. Moreover, we propose an extension of the method for successful guidance towards target locations outside the initial visual field. We conduct three perceptual studies, using 13 distinct panorama videos and two VR systems (a VR head mounted display and a fully immersive dome projection system), to investigate (1) general applicability to dynamic environments, (2) stimulus parameter and VR system influence, and (3) effectiveness of the proposed extension for out‐of‐sight targets. Our results prove the applicability of the method to dynamic environments while maintaining its unobtrusive appearance.

“…Adaptivity provides an opportunity to provide individual user experience (UX) and increase flow, presence, and immersion. Related work has shown, that behavioral indicators and biometric data for hand [6,9] and foot movements [5,8], as well as gaze behavior [7,11,12], can be used to adapt virtual environments and virtual reality (VR) [2,4]. The use of VR head-mounted displays (HMDs) provides the possibility to increase these effects by encapsulating users to their own environment.…”

Discussing the Risks of Adaptive Virtual Environments for User Autonomy

Adaptive virtual environments are an opportunity to support users and increase their flow, presence, immersion, and overall experience. Possible fields of application are adaptive individual education, gameplay adjustment, professional work, and personalized content. But who benefits more from this adaptivity, the users who can enjoy a greater user experience or the companies or governments who are completely in control of the provided content. While the user autonomy decreases for individuals, the power of institutions raises, and the risk exists that personal opinions are precisely controlled. In this position paper, we will argue that researchers should not only propose the benefits of their work but also critically discuss what are possible abusive use cases. Therefore, we will examine two use cases in the fields of professional work and personalized content and show possible abusive use.
