The two papers we read this week had a common theme that they enable collaboration, allowing multiple people to participate on a singular “workbench” though enable a personal view for each viewer. Each paper uses a different technique to enable head-tracking of each user. SCAPE: Stereoscopic Collaboration In Augmented and Projective Environments. Multiple users can […]
Scape: Supporting Stereoscopic Collaboration in Augmented and Projective Environments In the paper, Hua et al. talk about the design of a system that allows for collaboration in augmented environments. Their proposed system, Scape, allows for users to engage in face-to-face cooperation, while also providing each user with her unique stereo perspective for the augmented scene. […]
A Practical Multi-viewer Tabletop Autostereoscopic Display Autostereoscopic Displays provide stereoscopic perception without the use of special headgear or glasses on the part of the viewer. Lack of success in the adoption of autostereoscopic displays was justified by being expensive or cheap with a limited functionality. This study benefits from “Random Hole Display”(RHD) concept to produce […]
SCAPE: Stereoscopic Collaboration In Augmented and Projective Environments. SCAPE basically provides multiple users with a shared workspace so that they can concurrently observe and interact with the 3d virtual environment while face to face cooperation among local participants is preserved. This allows the users to dynamically switch focus between shared workspace and interpersonal communication space. […]
A Practical Multi-viewer Tabletop Autostereoscopic Display Autostereo display technologies can be divided into three branches, holo-graphics, volumetric, and parallax-based. Parallax-based displays are based on barriers or lenticular lens sheet. By placing barrier sheet at a small distance in front of the display panel, the left and right eyes of a viewer can see different part […]
Multi-viewer Tabletop Autostereoscopic Display The paper mentions a novel and practical Auto stereoscopic tabletop displays which would provide stereo perception to multiple users without special glasses. The main challenge is to provide multiple stereo viewpoints to different users at the same time through the same interface. Existing auto stereo display technologies mostly fall under three […]
Scape A 3D, interactive, collaborative, virtual environment is discussed in the paper. In this research an attempt to bridge the gap between virtual and augmented reality paradigms is met with success. This is achieved using range of devices such as Head Mounted Projective Displays, workbench, walled display, tracked objects in the room, magnetic trackers, DataGlove […]
A Practical Multi-viewer Tabletop Autostereoscopic Display Autostereoscopic display allows stereo perception without HMD or glasses, and allows people or objects to interact as if they were in the same place. However, it did not meet success for the while because of its price. The technique used here is the Random Hole Display (RHD) concept, but […]
Scape: Supporting Stereoscopic Collaboration in Augmented and Projective Environments -Hong Hua, Leonard D. Brown and Chunyu Gao Scape is a project aimed at allowing multiple users to collaborate on the same workbench using different AR and VR techniques. The authors have used head mounted projected displays with stereoscopic views, data gloves and surfaces coated with […]
Paper summary for week 7 by Andy To my mind, the work described in Ye, State, and Fuchs on Random Hole Displays means that increasing pixel densities in display technology can mean big gains for 3DUI. The RHD technology works by taking a high density display, and randomly sampling the visible pixels by obscuring the […]
Paper Presentation & Summary for Week 7 : Here are the links to my paper: 1) Main Paper – Scape: supporting stereoscopic collaboration in augmented and projective environments – Hong Hua, Leonard Brown and Chunyu Gao Here are the two related papers. The first one is relatively old while the second one is more recent compared to […]
Tabletop Autostereo This paper is about tabletop autostereoscopic display and its real-time rendering method. Their system allows viewers to see a different subset of pixels through the random-hole screen. Its advantage is to provide stereo perception without having users wear glasses. Their work is based on a previous concept named “Random Hole Display”. The authors […]
A Practical Multi-viewer Tabletop Autostereoscopic Display Autostereoscopic displays give a perception of 3D without wearing glasses and allow to see different images when moving around them. There is 3 types of autostereoscopic display : holographic, volumetric and parallax-based. Parallax based display could be made with: – a barrier with holes. When both eyes of the […]
SCAPE: Stereoscopic Collaboration In Augmented and Projective Environments. The paper introduces SCAPE a collaborative infrastructure for Augmented and Projective Environments. Scape aims at creating a virtual environment which could be accessible by multiple people at the same time. Earlier it was really difficult to provide individuals with their respective perspectives. Scape focuses on providing individuals […]
A Practical Multi-viewer Tabletop Autostereoscopic Display The paper discusses methods and technologies used to create a multi-viewer tabletop autostereoscopic display. The display had the requirements of multiple users begin able to see 3D content on the display from different angles. Previous work had been done in this area but the main driving factor in this […]
A Practical Multi-viewer Tabletop Autostereoscopic Display The authors introduce a multi-user autostereoscopic tabletop display and its associated real-time rendering methods. They use the “Random Hole Display” design that modified the pattern of openings in a barrier mounted in front of a flat panel display from thin slits to a dense pattern of tiny, pseudo-randomly placed […]
Multi-viewer Tabletop: This paper is about the construction and inner workings of a new type of Autostereoscopic table top display. The basic goal is to devise a display that will render different views to a number of users all position at various positions around the display. This problem has been attacked before using s few […]
Scape: Supporting Stereoscopic Collaboration in Augmented and Projective Environments This papers talks about a system that supports immersive and interactive virtual reality with multiple users. These augmented environment mainly contains two parts: the microscene on the workbench and macroscene on the walls. Microscene The microscene is projected on the workbench coated with a material called […]
A Practical Multi-viewer Tabletop Autostereoscopic Display This paper discusses a few of the technologies used to create stereoscopic displays that support multiple separate viewers without the need for user worn hardware such as glasses or head mounts. It begins with discussing the various existing technologies, focusing on the Random Hole Displays. The majority of the […]
A Practical Multi-viewer Tabletop Autostereoscopic Display Auto stereoscopic displays provide stereo perception without using glasses. The Random Hole Display inspires the system. RHD proposes a dense pattern of tiny, pseudo-randomly placed holes. Hence, multiple viewers at multiple locations will see multiple views. But those kinds of system are only calibrated for four users’ position and […]
