Do It Yourself Haptics: Part II [Tutorial]
IEEE Robotics & Automation Magazine, 2008Co-Authors: Karon Maclean, Vincent HaywardAbstract:This article is the second of a two-part series intended to be an introduction to haptic interfaces, their construction, and application design. Haptic interactions employ mechanical, programmed physical devices that can be used for human-computer communication via the sense of touch. In Part I of this series, we focused on the devices themselves: the classes of hardware schemes currently available or envisioned, the software components that drive them, and specific examples that can be built on the kitchen table. Here in Part II, we broach a topic that is coming into its own; between the vision of a particular utility that haptic feedback theoretically should enable and the hardware capable of delivering the required sensations is the problem of designing the interaction in a usable way.

Do it yourself haptics: Part I
IEEE Robotics and Automation Magazine, 2007Co-Authors: Vincent Hayward, Karon MacleanAbstract:A description on the methods that have been researched and developed is given to achieve the generation of haptic sensations, to show on how to construct experimental devices of modest complexity, and the necessary software components. This study aims to help new haptic interface designers by providing physical principles, hardware limitations, stability issues, and human perceptual demands. An overview of the primary categories of haptic displays and the solutions on the most common of these categories are both discussed. A review was done on the actuators, electronics, and software of vibrotactile stimulation. Then, the problem with force-feedback has been addressed by outlining the major subjects that underlie correct performance in this category. Lastly, an example was given regarding an emerging class of haptic display.

Do It Yourself Haptics: Part {I}
IEEE Robotics & Automation Magazine, 2007Co-Authors: Vincent Hayward, Karon MacleanAbstract:This article is the first of a two-part series intended as an introduction to haptic interfaces. Together they provide a general introduction to haptic interfaces, their construction, and application design. Haptic interfaces comprise hardware and software components aiming at providing computer-controlled, programmable sensations of mechanical nature, i.e., pertaining to the sense of touch. In Part I, we describe methods that have been researched and developed to date to achieve the generation of haptic sensations, the means to construct experimental devices of modest complexity, and the software components needed to drive them. In Part II of this series, we will describe some basic concepts of haptic interaction design together with several interesting applications based on this technology.

Do-It-Yourself virtual memory translation
2017 ACM IEEE 44th Annual International Symposium on Computer Architecture (ISCA), 2017Co-Authors: Hanna Alam, Tianhao Zhang, Mattan Erez, Yoav EtsionAbstract:In this paper, we introduce the Do-It-Yourself virtual memory translation (DVMT) architecture as a flexible complement for current hardware-fixed translation flows. DVMT decouples the virtual-to-physical mapping process from the access permissions, giving applications freedom in choosing mapping schemes, while maintaining security within the operating system. Furthermore, DVMT is designed to support virtualized environments, as a means to collapse the costly, hardware-assisted two-dimensional translations. We describe the architecture in detail and demonstrate its effectiveness by evaluating several different DVMT schemes on a range of virtualized applications with a model based on measurements from a commercial system. We show that different DVMT configurations preserve the native performance, while achieving speedups of 1.2× to 2.0× in virtualized environments.

Do It Yourself Hyperspectral Imaging with Everyday Digital Cameras
2016 IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2016Co-Authors: Seoung Wug Oh, Marc Pollefeys, Michael S. Brown, Seon Joo KimAbstract:Capturing hyperspectral images requires expensive and specialized hardware that is not readily accessible to most users. Digital cameras, on the other hand, are significantly cheaper in comparison and can be easily purchased and used. In this paper, we present a framework for reconstruct-ing hyperspectral images by using multiple consumer-level digital cameras. Our approach works by exploiting the dif-ferent spectral sensitivities of different camera sensors. In particular, due to the differences in spectral sensitivities of the cameras, different cameras yield different RGB mea-surements for the same spectral signal. We introduce an algorithm that is able to combine and convert these differ-ent RGB measurements into a single hyperspectral image for both indoor and outdoor scenes. This camera-based ap-proach allows hyperspectral imaging at a fraction of the cost of most existing hyperspectral hardware. We validate the accuracy of our reconstruction against ground truth hy-perspectral images (using both synthetic and real cases) and show its usage on relighting applications.
