A 3D Interactive System Based on Vision Computing of Direct-Flective Cameras

A bare-finger 3D air-touch interactive technology for portable devices has been developed. By using a directive-flective optical design on camera modules, the interactive range is workable from 1.5 to 50 cm above the entire surface of the display. Moreover, the motion vision computing, different from skin-color detection,to determine the position of fingertips will be discussed. The position mean errors were less than 1 cm. This accuracy realizes a camera-based interactive system allowing for near-distance 3D air-touch functionality. Therefore, floating 3D images can be touched and interacted with, potentially creating a more applicable and intuitive human-machine interface.

Portable Reference Images (PRI) for Augmented-Reality and Virtual-Reality Displays

As AR/VR migrates to smaller form factors with limited storage and compute power, the scene data driving the displays must be stored compactly and processed rapidly to generate positive user experiences. The Portable Reference Image (PRI) is a product specification developed to provide fluid visualization within these dynamic constraints.

Invited Paper:
Why Focus Cues (Blur and Accommodation) Matter

Stereoscopic displays present different images to the two eyes and thereby create a compelling 3D sensation. However, such displays cause a host of perceptual and ergonomic problems. These problems occur because some of the presented depth cues (i.e., perspective and binocular disparity) specify the intended 3D scene while focus cues (blur and accommodation) specify the fixed distance of the display itself. These problems are particularly problematic in VR and AR displays. A stereoscopic display that circumvents these problems has been developed. By using the display, how incorrect focus cues affect visual perception, visual performance, and, most importantly, visual comfort were investigated. The ability to perceive correct depth ordering is significantly improved when focus cues are correct. The ability to binocularly fuse stimuli is substantially improved when the vergence-accommodation conflict is minimized. The level of comfort is significantly increased when the vergenceaccommodation conflict is zero. Suggestions on ways to create nearly correct focus cues in practical stereoscopic displays, particularly VR and AR, will be presented.

Invited Paper:
A Simple Method to Reduce Accommodation Fatigue in Virtual-Reality and Augmented-Reality Displays

Available head-mounted displays for augmented reality and virtual reality provide many of the cues that a viewer senses in the real world, but not the important accommodation cue. Approaches to solve this problem have been considered, but proposed solutions come at significant cost in terms of image quality and system complexity. A simple system, based on electronic liquidcrystal lenses, is proposed. The design and performance of applicable electronic lenses will be presented. A surprising result of the proposed design is the potential for a reduced system bandwidth.

Invited Paper:
Light Fields, Focus Tunable, and Monovision Near-to-Eye Displays

Emerging virtual- and augmented-reality (VR/VR) displays must overcome the prevalent issue of visual discomfort to provide comfortable user experiences.In particular, the mismatch between vergence and accommodation cues inherent to most stereoscopic displays has been a long-standing challenge. Several display modes that have the promise to mitigate visual discomfort caused by the vergence-accommodation conflict (VAC) were evaluated, and user comfort as well as performance in VR/AR applications was improved. The light-field, focus-tunable, and monovision display modes were investigated. The effectiveness of several different display modes enabled by light-field and focus-tunable near-to-eye displays was evaluated.

Invited Paper:
RGB-D Image Understanding Using Supervision Transfer

Current advances in object recognition and scene understanding have been enabled by the availability of a large number of labeled images. Similar advances in RGB-D image understanding are hampered by the current lack of large labeled datasets in this domain. A new technique “cross-modal distillation” which enables transfer supervision from RGB to RGB-D datasets has been developed. Representations learned from labeled RGB images as a supervisory signal to train representations for depth images were used. A 6% relative gain in performance for object detection with RGB-D images was observed and a 20% relative improvement when only using the depth image was obtained.

Invited Paper:
A Wide-Field-of-View Head-Mounted Display and Its Effects on Search Performance in Augmented Reality

The development of a wide-field-of-view (FOV) optical see-through (OST) headmounted display (HMD) has been a challenge for decades. Naturally, the actual effects of a wide FOV OST display on the perception of augmentations have not been widely studied either. A wide FOV head-mounted projective display (HMPD) using a hyperboloidal semi-transparent mirror and a semi-transparent retroreflective screen, called a wearable HHMPD, was previously proposed. The main features of the wearable HHMPD include a horizontal FOV of 110° and a visual acuity of around 20/200. By using the wearable HHMPD, a user study investigating the effects of a wide FOV in AR was performed. Results show that target discovery rates consistently drop with in-view labelling and increase with in-situ labelling as display angle approaches 100° of FOV. Past this point, the performances of the two view management methods begin to converge, suggesting equivalent discovery rates at approximately 130° of FOV. Results also indicate that users exhibited lower discovery rates for targets appearing in peripheral vision and that there is little impact of FOV on response time and mental workload. A summary of the two studies will be provided.
