Flutter (company)

Flutter is a gesture recognition technology startup based in San Francisco, California, United States (US). Founded by Navneet Dalal and Mehul Nariyawala, the company received early-stage funding from Y Combinator and was acquired by Google X in October 2013.

History

The company's first product "Flutter App" allowed users to control apps such as iTunes, Spotify, VLC, and QuickTime using hand gestures. The app utilizes gesture recognition technology that works with the webcam on a user's computer. Instead of requiring separate hardware, such as Microsoft’s Kinect, Flutter makes use of the built-in webcam to recognize the gestures of a person's hands between one and six feet away.

The program does not require expensive hardware and is not designed for large movements, such as those used when playing video games—this limits its use to navigational duties. The company plans to achieve profit by licensing the technology to software companies that can then integrate Flutter into their own apps.

Aeroelasticity

Aeroelasticity is the branch of physics and engineering that studies the interactions between the inertial, elastic, and aerodynamic forces that occur when an elastic body is exposed to a fluid flow. Although historical studies have been focused on aeronautical applications, recent research has found applications in fields such as energy harvesting and understanding snoring. The study of aeroelasticity may be broadly classified into two fields: static aeroelasticity, which deals with the static or steady response of an elastic body to a fluid flow; and dynamic aeroelasticity, which deals with the body’s dynamic (typically vibrational) response. Aeroelasticity draws on the study of fluid mechanics, solid mechanics, structural dynamics and dynamical systems. The synthesis of aeroelasticity with thermodynamics is known as aerothermoelasticity, and its synthesis with control theory is known as aeroservoelasticity.

History

The 2nd failure of Samuel Langley's prototype plane on the Potomac has been attributed to aeroelastic effects (specifically, torsional divergence). Problems with torsional divergence plagued aircraft in the First World War, and were solved largely by trial-and-error and ad-hoc stiffening of the wing. In 1926, Hans Reissner published a theory of wing divergence, leading to much further theoretical research on the subject. In 1947, Arthur Roderick Collar defined aeroelasticity as "the study of the mutual interaction that takes place within the triangle of the inertial, elastic, and aerodynamic forces acting on structural members exposed to an airstream, and the influence of this study on design."

Flutter (2006 film)

Flutter is a 2006 Canadian anime-style animated short by Howie Shia, co-produced by PPF House and the National Film Board of Canada.

Awards

Flutter received the Open Entries Grand Prize at the Tokyo Anime Awards — the first work from outside Asia to win this award.Flutter also received the award for best Quebec short feature at the Fantasia Festival and a Jury Award from the Golden Sheaf Awards.

Plot

A film without color, a boy and a girl must abandon their friendship to pursue their dreams. In this short animation, a young boy takes a flying leap away from normal, waves goodbye to his classmates, and disappears into the cityscape and beyond. At the same time, a young girl is inspired to reinvent her space with art.

Production

Shia, who grew up in Saskatchewan, was in Montreal when he was approached by NFB producer Michael Fukushima and asked if he had any ideas he wanted to present. He offered a few ideas before remembering some earlier art work he had done of a "kid with wings on his feet" while working with the NFB on his first project, a 30-second short Ice Ages. This artwork became the inspiration for Flutter.

Flutter (electronics and communication)

In electronics and communication, flutter is the rapid variation of signal parameters, such as amplitude, phase, and frequency. Examples of electronic flutter are:

Flutter (2011 film)

Flutter is a 2011 British independent dark comedy film about gambling, written by Stephen Leslie and directed by Giles Borg. The film stars Joe Anderson, Ricky Tomlinson, Laura Fraser, Billy Zane, Anna Anissimova and Mark Williams.

Cast

Production

As of February 2010, Park Entertainment begun principal photography in filming northeast England, and began shopping the title to buyers in Berlin. Filming was completed in six weeks.
