Towards Applicable 3D User Interfaces for Everyday Working Environments

Abstract

Abstract. Desktop environments represent a powerful user interface and have been used as the de facto standard human-computer interaction paradigm for over 20 years. But the rising demand of 3D applications dealing with complex datasets exceeds the capabilities of traditional interaction devices and two-dimensional displays. Such applications need more immersive and intuitive interfaces. In order to be accepted by the users, technology-driven solutions that require inconvenient instrumentation, e.g., stereo glasses or tracked gloves, should be avoided. Autostereoscopic display environments equipped with tracking systems enable humans to experience virtual 3D environments more naturally, for instance via gestures, without having to use annoying devices. However, currently these approaches are used only for specially designed or adapted applications. In this paper we introduce new 3D user interface concepts for such setups which require minimal instrumentation of the user and can be integrated easily in everyday working environments. We propose an interaction framework which supports simultaneous display of and simultaneous interaction with both monoscopic as well as stereoscopic contents. We identify the challenges for combined mouse-, keyboard-and gesture-based input paradigms in such an environment and introduce novel interaction strategies.

RedirectedDoors+: Door-Opening Redirection with Dynamic Haptics in Room-Scale VR

“…Based on the above preconditions, we designed an algorithm based on a combination of Steer-to-Center (S2C) [15,50] and Steer-to-Action (S2A) [43]. S2C is one of the most basic generalized algorithms, and it determines the curvature and/or rotation gain of redirection so that the user's walking direction is toward the center of the play area.…”

“…Specifically, to provide haptic feedback during door opening at arbitrary positions in VR, we implemented a small number of wheeled robots (called door robots) equipped with a doorknob-like haptic prop and a robot-positioning algorithm to position them at proper timing while avoiding collisions. In addition, to guide the user away from the boundary of the physical play area, we designed and implemented a user-steering algorithm, based on existing algorithms [15,43,50], that adaptively determines the redirection gain for every instance of door opening. To evaluate the performance of RDD+, we first conducted a simulation study to investigate the effects of VE type, user walking speed, and number of door robots on the spatial efficiency of redirection and robot placement delay.…”

Use Cases for a Hybrid Augmented Reality Computer Workstation in Cad Workflows

“…Later, Bornik et al (2006) showed an interface for volumetric medical data combining a tablet PC with a stereoscopic projection and using a custom handheld input device for both modalities. Steinicke et al (2007) published a 3D interaction framework for everyday working environments, again using an autostereoscopic monitor with spatial and conventional input combined. Lately, Reipschläger and Dachselt (2019) extended an 2D interactive touch and stylus activated display with AR capabilities.…”
