the rochester cloak
Bookmarked 580 weeks ago
researchers at the university of rochester create a three-dimensionaltransmitting continuously multidirectional cloaking deviceinspired perhaps by harry potters invisibility cloak scientists have recently developed several wayssome simple and some involving new technologiesto hide objects from view the latest effort developed at the university of rochester not only overcomes some of the limitations of previous devices but it uses inexpensive readily available materials in a novel configurationthereve been many high tech approaches to cloaking and the basic idea behind these is to take light and have it pass around something as if it isnt there often using high-tech or exotic materials said john howell a professor of physics at the university of rochester forgoing the specialized components howell and graduate student joseph choi developed a combination of four standard lenses that keeps the object hidden as the viewer moves up to several degrees away from the optimal viewing positionthis is the first device that we know of that can do three-dimensional continuously multidirectional cloaking which works for transmitting rays in the visible spectrum said choi a phd student at rochesters institute of opticsmany cloaking designs work fine when you look at an object straight on but if you move your viewpoint even a little the object becomes visible explains howell choi added that previous cloaking devices can also cause the background to shift drastically making it obvious that the cloaking device is presentin order to both cloak an object and leave the background undisturbed the researchers determined the lens type and power needed as well as the precise distance to separate the four lenses to test their device they placed the cloaked object in front of a grid background as they looked through the lenses and changed their viewing angle by moving from side to side the grid shifted accordingly as if the cloaking device was not there there was no discontinuity in the grid lines behind the cloaked object compared to the background and the grid sizes magnification matchedthe rochester cloak can be scaled up as large as the size of the lenses allowing fairly large objects to be cloaked and unlike some other devices its broadband so it works for the whole visible spectrum of light rather than only for specific frequenciestheir simple configuration improves on other cloaking devices but its not perfect this cloak bends light and sends it through the center of the device so the on-axis region cannot be blocked or cloaked said choi this means that the cloaked region is shaped like a doughnut he added that they have slightly more complicated designs that solve the problem also the cloak has edge effects but these can be reduced when sufficiently large lenses are usedin a new paper submitted to the journal optics express and available on arxivorg howell and choi provide a mathematical formalism for this type of cloaking that can work for angles up to 15 degrees or more they use a technique called abcd matrices that describes how light bends when going through lenses mirrors or other optical elementswhile their device is not quite like harry potters invisibility cloak howell had some thoughts about potential applications including using cloaking to effectively let a surgeon look through his hands to what he is actually operating on he said the same principles could be applied to a truck to allow drivers to see through blind spots on their vehicleshowell became interested in creating simple cloaking devices with off-the-shelf materials while working on a holiday project with his children together with his 14 year-old son and choi he recently published a paper about some of the possibilities and also demonstrated simple cloaking with mirrors like magicians would usenote: a patent has been filed for this cloaking device please contact ur ventures for additional information: http:wwwrochestereduventuresaboutwho-are-we

elevenplay dance performance with drones at spiral hall
Bookmarked 598 weeks ago
abstract:this is a collaboration developed by elevenplayrhizomatiks who has been the pursuing possibilities of relationship and interaction between the body and technology by interacting with a variety of hardware and devices such as robot arms and motor-controlled floating balls in this new work objects are arranged three-dimensionally in real space through a tracking technology and drone control system and the work in which dancers give performances has been presented so as to find the possibility of a new bodily expression context:with the development of video and image analysis technologies trials to deal with the body as data and to expand the body have been conducted using such methods as virtual reality and augmented reality one problem was for instance that a dancer had to wear a head mounted display or while looking at images on a projector since an intuitive approach is still difficult a new experimental work employing advanced control and analysis technologies is required as there is a limit to the output of images it is necessary to use physical devices and objects so as to expand bodily expression presented in real spaceperformance:a system in which dancers can physically and more intuitively perceive the relationship between the body and data through computer-controlled drones has been developed there are two kinds of drone movements: a motion produced by tracking a dancer039s movements and an artificial motion operated on the software at first dancers had to be trained to interact with the drones because they could not predict how they would move but eventually they were able to dance with the drones as closely as 10cm away from themsystem installation: cameras with the motion capture system are used for the position analysis of the drones 10 to 15 of which are needed they are installed on the ceiling with a camera mount or set up around the stage using tall tripods three retro reflective markers are attached to each drone so as to identify the position and angle see the figure for detailssystem hardware:using the position information of the drones tracked by the motion capture system the positions of three drones are controlled through feedback control asctec hummingbird 2012 is used for the drones in order to cope with problematic situations manual operation is available at anytime so if the tracking system has a problem the drones can be landed automatically and safelysystem software:flight patterns have been created through various methods eg producing them with original software importing data from cg software and using ableton live for the analysis of the dancers039 movements the conventional method is used with retro reflective markers attached to them and motion capture cameras we adopted a method in which these data are recorded or captured in real time processed and played back so that the drones move according to the dancers039 movements three-dimensional object:a quadrangular pyramid-shaped object is attached to the upper part of each drone for better visual confirmation in the beginning a sphere-shaped object was used but it was difficult to confirm the drone039s spinning movements visually that is why an object of another shape was used while motion is restricted due to greater air resistance a quadrangular pyramid-shaped object was attached in order to improve expression and secure dancers039 safetyphysical motion:the dance shows the beauty and difficulty which come from resistance to gravity and inertia viewers are able to appreciate this naturally through their experience and the same thing applies to the drones the limits motion dynamism and a locus that is impossible to make with cg are produced by physical laws such as gravity inertia and air resistance though the three-dimensional object was originally attached to improve visibility it eventually played not only the role of making drones look bigger but also became an important element in emphasizing the motion and visualization of the interaction between the dancers and the laws of physics projection:as a step further a projection was sometimes conducted for the object attached to the drone in order to improve visibility while the system functions the content has potential for further development the work will be continually updated in the futureartistic direction and choreograph: mikikoelevenplayartistic direction and programming: daito manaberhizomatiksdance:aya koumenelevenplayerisa wakisakaelevenplaykaori yasukawaelevenplayhardware and firmware engineering: motoi ishibashirhizomatiksprogramming: satoru higarhizomatiks satoshi horiirhizomatiksmotion graphic design: takcommusic: ametsubsupport: rhizomatiks elevenplay and picsspecial thanks to ycam
