NEW EYE TRACKING TECHNIQUES IMPROVE REALISM OF AIR Essays - Eye

NEW EYE TRACKING TECHNIQUES IMPROVE REALISM OF AIR Essays - Eye NEW EYE TRACKING TECHNIQUES IMPROVE REALISM OF AIRCRAFT SIMULATORS NEW EYE TRACKING TECHNIQUES IMPROVE REALISM OF AIRCRAFT SIMULATORS A simulated flight environment for pilot training may soon be made more realistic through the use of eye-tracking technology developed by researchers at the University of Toronto's Institute of Biomedical Engineering (IMBE). Many safety and cost benefits are obtained by training aircraft pilots under simulated conditions, but to be effective the simulation must be convicingly realistic. At present, th e training facilities use large domes and gimballed projectors, or an array of video screens, to display computer-generated images. But these installations are very expensive and image resolution is low. Further, it would take an enormous amount of addi to improve image quality significantly throughout the whole viewed scene. However, based on the visual properties of the eye, realism can be obtained by providing a high-resolution 'area of interest' insert within a large, low-resolution field of view. If the image-generating computer 'knows' where the pilot's fixation is, it mage there. The technology to make this possible was developed by a research team headed by Professor Richard Frecker and Professor Moshe Eizenman. The work was carried out in collaboration with CAE Electronics Ltd. of Montreal with financial support from the Natural Sciences and Engineering Research Council of Canada. Their eye-tracker can record and analyze accurately up to 500 eye positions per second. The system works by means of capturing and processing the reflections of a low-level beam o f invisible infra-red light shone onto the eye. Multi-element arrays capture the image of the eye and digitize the information, which is then processed in real time by a fast, dedicated signal processing unit. The difference in position between the ligh tre of the pupil reveals the instantaneous direction of gaze. Developments by the IBME team have significantly increased the speed of signal processing in addition to enhancing accuracy of eye position estimates. Eizenman believes that "these improvements make our eye-tracker very effective in monitoring the large G-force environment where the pilot tends to make larger eye movements because of contraints which exist on movements of his head". In a new generation of aircraft simulators, under development by CAE Electronics Ltd. of Montreal, a head tracker which tells the direction of the pilot's head is mounted on top of the helmet. The eye tracker is mounted on the front of the helmet, and is ll exactly where the pilot's eye is fixating. Frecker said that "successful integration of our eye tracker into the novel helmet-mounted CAE flight simulator would result in a new generation of simulators that would likely replace the current large domes and cumbersome video display units." Initial tests of the integrated system will be carried out in collaboration with CAE Electronics at Williams Air Force Base in Arizona later this year.

A college essay is a writing assignment meant to be a companion to a college application. A standard college essay supplements the academic performance and standardized test scores for an admissions office and allows the students to give a more qualitative expression of themselves, contributing to a complete profile on their application. In some cases, college essays may be free form expressions for the students writing them, but often colleges will provide a prompt or list of topics on which to write, given an assigned word count range. This can take the form of a standard essay, or resemble a reflection or personal essay, depending on the stipulations of each college. In the United States, many colleges are using the Common Application, using standard essay topics and making the entire application process much less time consuming and more convenient for students. How to Write a College Essay To write a college essay, first consider the prompt or topic at hand, and how it applies to your life. It is important to consider several options to tie in the essay topic to your personal life experiences so that you can judge these options against each other. When you’ve decided on an experience or narrative that you feel reflects you in your best light, start writing. Follow these guidelines for the best college essay results: 1. Stay With Your Own Voice. When writing their college essays, many applicants may feel pressured to present themselves in a different light than they would in any other context. The fact is, you tend to do your best writing in the tone and voice where you feel the most comfortable. Don’t try to stretch your comfort zone to impress the person reading your essay. 2. Hold Your Reader’s Attention. As you write, think to yourself: â€Å"is this something I would enjoy reading?† Remember, the person reading your essay probably reads countless others each year. To make sure yours stands out and captivates, remember to reflect rather than simply recount events as you go through a narrative. This will help your work remain original, creative and hold the attention of the reader. 3. Answer the College Essay Prompts Directly. College admissions offices are looking for a creative, well-thought and well-crafted essay. To produce this result, make sure that you’re answering the prompt directly and reiterating that answer throughout your work. This will help you stay on-topic and remain clear and concise all the way through your essay. 4. Edit and Edit Again. You will likely need several drafts before you have a final version that you’re happy with, even after exploring all of your subjects strategies in thorough detail. Make sure you re-read over and over as you go, down to the smallest detail and phrase. Each small improvement can have a major effect on the way your writing flows, and each idea becomes cohesive throughout. Remember also to have at least one proofreader; a fresh pair of eyes can be the difference between an impressive college essay and another one the pile for admissions offices. 3 STEPS TO A GREAT COLLEGE ESSAY College Essay Format College essays typically take the form of reflective essays or personal statements. While there is no uniform distribution of content in a college essay, the following structure can be followed as a general rule for clarity: Introduction: this should be a single paragraph that provides an overview of the essay’s main ideas, answers the question in the prompt and provides context for the rest of the essay. Like a research abstract, the introductory paragraph allows the reader to comprehend the entirety of the essay before getting into the details, or the narrative. Body: the body of a college essay has the most variability, as it depends on the topic and length of the essay itself. For most college essays, plan to have 1-3 body paragraphs that tell a clear, concise and engaging story about your personal development and growth. As a general rule, each body paragraph should have a different focal point. Be sure to consider this stipulation as you plan the parts of your essay before you begin to write. Conclusion: the conclusion of a college essay should restate the central themes of the piece without simply restating the introduction or the parts of the narrative. The key is to find a unique way to wrap things up that shows the level of growth and development the applications office is looking for, clear and concise. COLLEGE APPLICATION ESSAY College Essay Prompts While college essay prompts can resemble prompts typical of a reflective essay, there may be more emphasis on personal accomplishments. Think of it as a resume, in a longer format. With more and more colleges moving to the Common Application, college essay prompts are more standardized than ever. Here are some of 2015’s Common Application prompts, courtesy of the Princeton Review. â€Å"Recount an incident or time when you experienced failure. How did it affect you, and what lessons did you learn?† â€Å"Discuss an accomplishment or event, formal or informal, that marked your transition from childhood to adulthood within your culture, community, or family.† College essay prompts are meant to be complicated so that responses are as varied as possible.
