Sger: Analysis of Solution Space to Achieve Ubiquitous Pixels @ University of California-Irvine
Ubiquitous pixels is a grand vision shared by many researchers in graphics, vision, and HCI. Conceptually, ubiquitous pixels envisions pixels being lit everywhere and anywhere around the user and are used both as information carriers and interaction agents. A system of ?sea of projectors and cameras? has been identified as the right medium to push the envelope to achieve this vision. But even after a decade, only a small part of the vision has been realized. The reason for this is the complexity of the problem and a common belief that many parts of the problem are intractable. This project involves an analysis of the feasibility of achieving ubiquitous pixels under various conditions of known and unknown display and device (projectors and cameras) parameters. The project will identify the aspects of the problem, if any, that are theoretically intractable as against those that are limited by current technology.
Intellectual Merit: The project will identify constraints and guidelines that would make ubiquitous pixels realizable to those on display surfaces, projectors, cameras and other sensors that are used in interactive environments. The project will specify the theoretical constraints that should be imposed on these devices that will make this problem tractable. The project will set a research agenda by identifying the fundamental set of physical features that need to be provided in the device and the environment to make ubiquitous pixels feasible.
Broader Impact: The primary long-term impact of this proposal lies in advances made to realize ubiquitous pixels - pixels anywhere and everywhere. Ubiquitous pixels have a tremendous potential to change the way we interact with the environment in the future. Specifically, the project will advance the frontier of research to create pack-and-go high resolution displays where one can pack multiple display units at the back of their car trunk, deploy them on any environment in minutes, dismantle them and take them elsewhere when needed. It can also make advances for next generation visualization, training and simulation systems that are entirely seamless with an order of magnitude greater resolution than current displays (from millions to billion pixels by using hundreds of projectors) and can scale easily to accommodate the incredible rate of the growth of data in the recent years.

Career: Ubiquitous Displays Via a Distributed Framework @ University of California-Irvine
"This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)."
In this project the PI will explore a new paradigm where displays are not mere carriers of information but rather active members of the workspace capable of interacting with data, users, the environment, and other displays. The goal is to seamlessly integrate such active displays into the collaborative workspace of the future, so that they become ubiquitous and critical components. To these ends, the PI plans to utilize a projector augmented with sensors along with an embedded computation and communication unit. She will investigate the challenges and capabilities resulting from instrumenting a workspace with a network of such projectors, including novel distributed methodologies to: (a) cover the existing surfaces (walls, floors, etc.), which can deviate considerably from planar, white and Lambertian, with multiple active displays; (b) provide scalability and reconfigurability (in terms of scale, resolution and form factor) of displays; and (c) provide a framework for shared viewing and interaction modalities for multiple users. Achieving such objectives will require the ability to register imagery globally with the underlying display surface via multiple local corrections. For interaction with users, the PI will develop distributed methodologies for gesture-tracking and use them as the cornerstone for a gesture-based shared interaction modality for large-scale data visualization and modification. For interaction with data, application-independent distributed windows management middleware (tentatively dubbed overloaded windows) will be developed. The new technologies will be combined to provide a novel "data mobilizer" application for scanning, storing and interacting with life-size image-like artifacts. All of these technologies will be evaluated in collaboration with the Environment to Environment Communication (E2E) project at National University of Singapore (NUS). Project outcomes will include novel ways for precise and scalable digital control of light on large architectures, distributed scene reconstruction for large inside-looking-out environments, metrics to evaluate optimal sampling criteria for reconstructing such scenes, design criteria to accommodate multiple viewers in a collaborative environment, novel distributed shared-interaction modalities in such environments, and a new distributed data management paradigm via overloaded windows.
Broader Impacts: This project will lead to gesture-based multi-user interaction modalities for mobilizing data in collaborative environments for next-generation visualization, training and simulation applications with a display resolution that is an order of magnitude higher than what is currently available yet which can be maintained and deployed much more easily. The diverse potential applications include digital display domes for education and entertainment purposes, precise digital lighting techniques for exploration of cultural heritage such as large edifices, and novel body-based interaction tools for creating life-size artistic expressions.

Eager: Reaqtive - Resource Aggregation and Quality Tradeoffs For Integration of Video Projector Ensembles @ University of California-Irvine
The objective of this research is to integrate multiple quality-constrained cell-phone-based pico-projectors as to create quality output and improve the viewing experience of users 'on the go' during a multimedia session, i.e., watching a video, or sharing a multimedia presentation. The proposed approach is to develop coding and decoding schemes to allow flexible split stream media delivery that takes into account the number of displays for image partitioning and accommodates a range of resolutions, frame rates, and device power resources. Additionally, novel synchronization schemes that integrate display synchronization and video/audio stream synchronization across multiple devices will be investigated. Current multi-projector registration techniques need to be modified for resource and quality sensitivity for use in low-quality pico-projectors.
The project proposes a new paradigm of resource management, device synchronization and video coding/decoding for portable multimedia devices to collaboratively deliver an enhanced viewing experience for users, where 'enhanced' refers to frame rate, image resolution, brightness, audio quality, and power savings for longer viewing. This paradigm parallels the MIMO concept in wireless communications by introducing spatial diversity in video display. MIMO enhances the data rate and/or the signal quality, the results of this project is expected to enhance the image resolution and/or brightness.
The proposed paradigm will allow multiple users to pool the resources of mobile portable devices to produce a higher quality, energy/resource efficient output, anywhere, anytime. This will impact users 'on the go' in ad hoc settings, ranging from media sharing in social milieus to first responders and emergency workers requiring higher quality image output in the field.
