Book excerpt: Previous research efforts have shown that the compound vision system of a common house fly, Musca domestica, is capable of improved motion detection and tracking capabilities when compared to traditional camera systems. Especially in applications requiring object detection, obstacle avoidance, and quick visual data processing, these compound vision sensors are more suitable as compared to the usual mammalian inspired vision systems. Proof-of-concept has shown that even without using a computer processing system, existing compound vision sensors can mimic the motion hyperacuity characteristic of the fly's visual system and at the same time provide near instantaneous edge detection and motion tracking. However, the existing sensor design consists of seven photodiodes which generate artifacts in the output signal. This type of sensor design has been implemented in analog circuitry and was found to have limited capability to detect different types of edges. Therefore, to advance the state-of-art of existing fly eye vision sensors, certain design changes were done in this work to avoid these signal artifacts. Moreover, a digital equivalent of the existing analog circuitry has been designed and tested without losing the motion hyperactivity characteristic of the sensor. Furthermore, for the existing seven photodiode sensor designs, an improved edge detection algorithm has been designed that correctly classifies horizontal and vertical edges as the previous design could but can now also correctly detect and classify diagonal edges. Taking a step further, a multi-cartridge sensor design has been proposed that can further enhance the sensor's capability to detect single edges as well as correctly classify the corners present in the sensor's field-of-view.

Available in PDF, EPUB and Kindle. Book excerpt: Previous research efforts in mimicking the compound eye of Musca domestica, the common house fly, in hardware have primarily been focused on optical designs to achieve the fast, analog, parallel processing and motion hyperacuity properties of the biological system. While these optical platforms have shown promising results, nearly all proposed advantages of utilizing a fly-inspired sensor have been discovered through the use of software simulation with very little or no effort being made to validate these simulations using the actual fly-inspired optics. In effect, these simulations can be viewed as the first step into mimicking the function of the intermediate neural layer structure (the lamina) of the fly's visual system. The lamina is believed to perform preprocessing on image data, extracting motion and object information from the scene before sending it to the brain. The work presented in this dissertation advances the frontier of compound vision research by mimicking the function of the lamina structure in hardware. The hardware designs were kept as biomimetic as possible: no system clocks were used, system-wide parallel operation was never violated, and discrete-time (digital) solutions were not considered unless absolutely necessary. In addition, the unique motion hyperacuity characteristic of Musca's visual system was preserved in each circuit design. The specific lamina functions that were mimicked in device-level electronics are the light adaptation process and a software proposed edge detection process. It will be shown that an effective light adaptation system can be designed that is both analog and parallel by directly mimicking the fly's visual system. It will also be shown that the edge detection system can be designed to utilize the underlying structure that allows for motion hyperacuity to improve the accuracy of locating small linear objects such as power lines. The proof-of-concept designs presented in this dissertation are an important first step in turning the novel compound optical designs of the past decade into useful sensors that can function in dynamic real-world environments and that are capable of on-board biomimetic image processing.

Available in PDF, EPUB and Kindle. Book excerpt: Musca domestica, the common house fly, has a very simple yet powerful vision system. Fly-inspired vision sensors have been developed that display many interesting qualities, such as extreme sensitivity to motion, outstanding edge detection capabilities, and hyperacuity. The Wyoming Information, Signal Processing, and Robotics (WISPR) Laboratories have an on-going research effort to apply lessons learned from the fly's vision system towards the development of novel analog vision sensors. The research efforts described in this thesis contribute new finding to both the electrophysiology and sensor development areas of the WISPR project by accomplishing the following: analyzing the electrophysiology instrumentation and modeling some fly inspired features at the cartridge level. The analysis of the instrumentation verifies the stimuli provided to the fly during electrophysiology recording. This work is critical in the proper analysis of previously captured electrophysiology recordings. Additionally, the model of the cartridge structure within the fly's vision system has been augmented to include sensor orientation, light adaptation, lateral inhibition, and spot location features. These enhancements will guide the design and development of the next generation of physical sensors.

Available in PDF, EPUB and Kindle. Book excerpt: The goal of this research is to develop an imaging system based on the visual system of the common housefly, Musca domestica. While traditional imaging systems (which resemble the human visual system) are well suited for a wide variety of image processing tasks, sensors based on the fly's multi-aperture visual system show promise in specific applications, including motion and edge detection. This thesis quantifies, in signal processing terms, how the fly is able to achieve motion acuity much higher than its photoreceptor spacing suggests (a phenomenon called "hyperacuity"). Next, this information is used to optimize motion hyperacuity in an optical model of a new, more compact fly eye sensor. The optical model is used to design a hardware implementation of the sensor. Finally, the newly designed sensor is shown to outperform fly eye sensors previously developed at the University of Wyoming.

These range from retinal development in fish and frogs to the effects of abnormal visual experience on the primary visual cortex of the cat. The book is unique in addressing four specific and fundamental aspects of development: cell lineage and cell fate, specificity and targeting of axons, specification of visual cortex, and correlates of the critical period. Encompassing technical advances in cellular and molecular biology and in video imaging and microscopy, contributions in each of these areas provide new information at the cellular and molecular levels to complement the now classic descriptions of visual development previously available at the level of neural systems.ContributorsKaren L.

Available in PDF, EPUB and Kindle. Book excerpt: Most programmers' fear of user interface (UI) programming comes from their fear of doing UI design. They think that UI design is like graphic design—the mysterious process by which creative, latte-drinking, all-black-wearing people produce cool-looking, artistic pieces. Most programmers see themselves as analytic, logical thinkers instead—strong at reasoning, weak on artistic judgment, and incapable of doing UI design. In this brilliantly readable book, author Joel Spolsky proposes simple, logical rules that can be applied without any artistic talent to improve any user interface, from traditional GUI applications to websites to consumer electronics. Spolsky's primary axiom, the importance of bringing the program model in line with the user model, is both rational and simple. In a fun and entertaining way, Spolky makes user interface design easy for programmers to grasp. After reading User Interface Design for Programmers, you'll know how to design interfaces with the user in mind. You'll learn the important principles that underlie all good UI design, and you'll learn how to perform usability testing that works.

Available in PDF, EPUB and Kindle. Book excerpt: The study of human body measurements on a comparative basis is known as anthropometrics. Its applicability to the design process is seen in the physical fit, or interface, between the human body and the various components of interior space. Human Dimension and Interior Space is the first major anthropometrically based reference book of design standards for use by all those involved with the physical planning and detailing of interiors, including interior designers, architects, furniture designers, builders, industrial designers, and students of design. The use of anthropometric data, although no substitute for good design or sound professional judgment should be viewed as one of the many tools required in the design process. This comprehensive overview of anthropometrics consists of three parts. The first part deals with the theory and application of anthropometrics and includes a special section dealing with physically disabled and elderly people. It provides the designer with the fundamentals of anthropometrics and a basic understanding of how interior design standards are established. The second part contains easy-to-read, illustrated anthropometric tables, which provide the most current data available on human body size, organized by age and percentile groupings. Also included is data relative to the range of joint motion and body sizes of children. The third part contains hundreds of dimensioned drawings, illustrating in plan and section the proper anthropometrically based relationship between user and space. The types of spaces range from residential and commercial to recreational and institutional, and all dimensions include metric conversions. In the Epilogue, the authors challenge the interior design profession, the building industry, and the furniture manufacturer to seriously explore the problem of adjustability in design. They expose the fallacy of designing to accommodate the so-called average man, who, in fact, does not exist. Using government data, including studies prepared by Dr. Howard Stoudt, Dr. Albert Damon, and Dr. Ross McFarland, formerly of the Harvard School of Public Health, and Jean Roberts of the U.S. Public Health Service, Panero and Zelnik have devised a system of interior design reference standards, easily understood through a series of charts and situation drawings. With Human Dimension and Interior Space, these standards are now accessible to all designers of interior environments.
