הבעיה של גוגל: צירוף של מספרים לא בהכרח מניב מסקנות נכונות - גלובל - אתר חדשות כלכלה ונתוני בורסה מישראל ומהעולם TheMarker דה מרקר ניק בילטון מ"ניו יורק טיימס": "אנחנו ממהרים להשתמש בנתונים של גוגל ושוכחים כי מדובר באסופת מספרים שמתעלמת מההקשר" לפני מספר שנים גוגל יצרה משוואה מפוארת שיכולה לפענח כמה אנשים חולים ברגע מסוים בשפעת. החשבון עבד כך: מיקום האדם יחד עם חיפוש הקשור לשפעת במנוע גוגל בתוספת אלגוריתמים חכמים במיוחד: מספר האנשים בארה"ב החולים בשפעת. ניק בילטון מספר בבלוג ב"ניו יורק טיימס" כי בעוד לפי נתוני גוגל, בחורף הנוכחי 11% מאוכלוסית ארה"ב היתה חולה בשפעת, ולפי מאמר שפורסם במגזין המדעי Nature, האלגוריתמים של גוגל שגויים והתוצאות כפולות לעומת הנתונים של המרכז האמריקאי לפיקוח על מחלות שמדווח על 6% מהאמריקאים חלו בשפעת. לפי בילטון, ייתכן שהבעיה באלגוריתם של גוגל היא כי הוא מסתכל על מספרים, ולא על תוכן. "בעולם של היום, המידע נמצא בכל מקום. בילטון מוסיף חוויה דומה שהתרחשה כאשר לימד באוניברסיטת ניו יורק ב-2010. לפי תוצאות הניסוי, סטודנטים השתמשו במעליות בשעות הבוקר, כנראה כי עוד היו עייפים מהלילה, ובלילות עברו לשימוש במדרגות.
<FM modulated doppler radar for human gesture sensing> a measurement device by Godfried-Willlem Raes a doppler radar based gesture measurement system capable of delivering positional information by dr.Godfried-Willem Raes postdoctoral researcher Ghent University College & Logos Foundation This technical note is a continuation of reports on many earlier designs for gesture sensing apparatus using both sonar and radar technologies. Doppler based microwave devices can be used to make pretty good movement sensors with a range from very nearby to about 20 meters. For the project we are reporting here, the following devices are examined: MDU1100 (Microwave Solutions Ltd.): X-band, operating microwave frequency is specified at 10.587 GHz. MDU2400 (Microwave Solutions Ltd).: K-band, operating microwave frequency 24.2 GHz. RSM1700 (Conrad), IPM170 (Microsense), Amiwima DRM-24 (Allsat Gmbh) devices operating around 24.125 GHz. Doppler formula: fd = 2 v fo / c fo = operational frequency c = speed of light fd = Doppler frequency v = movement speed in line with the antenna expressed in m/s Software Dr.
Big-Bang Disruption By now any well-read executive knows the basic playbook for saving a business from disruptive innovation. Nearly two decades of management research, beginning with Joseph L. Bower and Clayton M. Christensen’s 1995 HBR article, “Disruptive Technologies: Catching the Wave,” have taught businesses to be on the lookout for upstarts that offer cheap substitutes to their products, capture new, low-end customers, and then gradually move upmarket to pick off higher-end customers, too. When these disrupters appear, we’ve learned, it’s time to act quickly—either acquiring them or incubating a competing business that embraces their new technology. But the strategic model of disruptive innovation we’ve all become comfortable with has a blind spot. That advice hasn’t been much help to navigation-product makers like TomTom, Garmin, and Magellan. The disruption here hasn’t come from competitors in the same industry or even from companies with a remotely similar business model. A Difference in Kind
Eight UX Design Trends for 2013 One of the best things about user experience design is that the consumer products and services it helps to crystallize are always evolving. With that level of change comes all sorts of speculation about the future. Speculating is fun. Downsampling The Onion hit it spot-on when they joked that 90% of our waking lives are spent staring at glowing rectangles. Little Printer skims headlines from your online feeds and spits them out as low-fi ticker tape for your bedside. Foodism Food has replaced art as high culture. This year, specialized products, processes, and mobile applications will catalyze new levels of culinary geekiness. Quantifed Ambition “How to win friends and influence people” has been the core ambition of go-getters since Dale Carnegie’s influential 1936 book of the same name hit shelves. Augmented Dialogue Mobile tech has already stepped in to help us search and discover, navigate, and buy stuff. Sensory Bandwidth Agile Economies Faceted Video Key indicators? RetroFuturism
InSight team's wearable glass system identifies people by clothes (Phys.org) —Researchers from the University of South Carolina and Duke are proposing a "visual fingerprint" app that can be used with smartphones and wearable camera displays such as Google Glass. Their paper, "Recognizing Humans without Face Recognition," explored techniques that can jointly leverage camera-enabled glasses, an offering that is still in the wings, and phones, to pick out any individual based on what the person is wearing. The team behind the InSight project developed and tested a prototype system that can pick out people by their clothes and other accessories. The system was developed by Srihari Nelakuditi, associate professor of computer science and engineering at the University of South Carolina, along with three colleagues at Duke University, He Wang, Xuan Bao, and Romit Roy Choudhury. How InSight works: A smartphone app creates a person's "fingerprint" by taking a series of pictures of the person. What's the point of the app? What's the limitation?

Image 2: A comparison between the (ground truth) image being focused on the sensor surface and the reconstructed image (inset). WASHINGTON, Feb. 20, 2013— Digital cameras, medical scanners, and other imaging technologies have advanced considerably during the past decade. The new imager, which resembles a flexible plastic film, uses fluorescent particles to capture incoming light and channel a portion of it to an array of sensors framing the sheet. For the luminescent concentrator to work as an imager, Bimber and his colleagues had to determine precisely where light was falling across the entire surface of the film.

52 Weeks of UX The user experience is made up of all the interactions a person has with your brand, company, or organization. This may include interactions with your software, your web site, your call center, an advertisement, with a sticker on someone else’s computer, with a mobile application, with your Twitter account, with you over email, maybe even face-to-face. The sum total of these interactions over time is the user experience. The interaction designer plans for these moments. Part of their responsibility is to make all interactions positive, and includes aspects of the software, the copy-writing, the graphics, layout, flows, physical experiences. User experience spans multiple practices. Web designers, traditionally secure in the role of page creators, now have a wider purview. The 150 Things the World's Smartest People Are Afraid Of Every year, the online magazine Edge--the so-called smartest website in the world, helmed by science impresario John Brockman--asks top scientists, technologists, writers, and academics to weigh in on a single question. This year, that query was "What Should We Be Worried About?", and the idea was to identify new problems arising in science, tech, and culture that haven't yet been widely recognized. This year's respondents include former presidents of the Royal Society, Nobel prize-winners, famous sci-fi authors, Nassem Nicholas Taleb, Brian Eno, and a bunch of top theoretical physicists, psychologists, and biologists.

Design Thinking | Thoughts by Tim Brown The 12 Trends That Will Rule Products In 2013 | Co.Design: business + innovation + design Near the end of 2012, a group of us at Ziba got together to review what we’d learned over the course of the year. Working with dozens of clients who serve customers around the world, we designers spend a lot of time observing people as they interact with technology, services, and experiences, noticing how they seek solutions to everyday problems and make decisions. In the process, certain patterns emerge so forcefully that they’re practically unavoidable. Meeting over three sessions spread out over a week, 23 Zibites (designers, researchers, and creative directors) discussed the patterns we’d seen, and distilled them down to the 12 insights we thought were most current and useful, to us and to our clients. Each one is presented here, as a brief essay that suggests how it will affect business practices in 2013, and as an illustration created by one of Ziba’s designers. 1. Our understanding of how we decide has evolved dramatically over the past 20 years, and it paints a messy picture. 2.
