Gabriela Barreto Lemos – Quantum Photography – Brazil

Quantum photography technique that allows you to record images without light passing through the object.

Typically, a beam of light interacts with an object; In this same beam, the image of that object is formed, which is recorded on a camera, on paper or directly into the eye. This research used two quantumly entangled photon beams. An infrared photon was directed at a silicon wafer engraved with the image of a cat. The other photon, red, was sent on a different trajectory, did not pass through the silicon plate and was detected by an EMCCD (electron-multiplying charge-coupled device – a photographic camera with sensitivity to very low intensity light). The image of the cat engraving was recorded by the camera, which only detected the red light, which did not touch the engraving. It is the first time that an image has been captured in a beam of light that has not interacted with the object that produced the image.

The experiment, led by researcher Gabriela Barreto Lemos, was carried out at the Institut für Quantenoptik und Quanteninformation in Vienna, 2014.

The technique has potential for applications in indirect image capture, from medicine to quantum computing.

Squint
file festival
I was inspired by how the sunlight bounces around in our artificial forest.
“Squint” is a kinetic light installation consisting of 49 mirrors that reflect lights in a bright space. The mirrors track and reflect lights on audiences’ face with composed patterns of movements. It extends the generated perception by focusing on how lights pass across our visual senses physically, and combines with our perception of images through flickering. “Squint”, which extracts various daily experiences to an abstraction brings the audience to expand their interpretation of lights and perceived imagination into a non-linear experience.
“Squint” simulates light source and intentionally shines lights on audience’s faces. Bright light is projected in the gallery, a clean bright space.
Everyday people are dynamically moving around in the city. Sunlight reflects and flickers even when it is indirect and hidden behind the artifacts. While we are traveling, we are experiencing motion. We are also experiencing the shift of light intensity, visual patterns and textures. The varieties of light forms inspire the artist to explore the potential of light textures, select and sort out the combined complexity in urban space. The artist turns them into a minimal form of light experience, while maximizing its diversity of perception.

YOU WOULD COME BACK THERE TO SEE ME AGAIN THE FOLLOWING DAY
This installation utilizes mirrors and video cameras combined with various types of frame, a motif often discussed in the context of the history of painting and film. The title is a typical English sentence in free indirect speech (by what is normally a third-person subject). With the object of “there” and “following day” varying with the context, this title reflects the experience of viewers, whose relationship to their image and to the space raises questions about the meaning of “here” and “now.”

move
File Festival
MOVE is an interactive installation divided into six distinct modules, JUMP, AVOID, CHASE, THROW, HIDE and COLLECT. Each module offers a single-user interaction, based on a verb corresponding to the action the participant is invited to perform. Each verb corresponds to a common procedure acted out by avatars during videogame play. Each module offers an interaction with abstracted shapes (circles, rectangles) behaving according to simplified rules of physics (collision, friction). Each module is color-coded with consistency, where the color red is used for the graphical element that poses the core challenge. Each module increases difficulty in a similar linear manner.What makes MOVE unusual is that unlike most computer vision or sensor based games like Eye-toy or Dance Dance Revolution, the participant IS the avatar, he is not seeing a representation of herself or an indirect result of her actions on a separate screen but instead interacts directly with the projected graphical constituents of the game. Because those graphical elements are non-representational they do not allow for a projection in a fictional space. The combination of abstracted shapes and direct interaction reinforces in the player the focus on the action itself (JUMP, AVOID, CHASE, THROW, HIDE or COLLECT) instead of an ulterior goal.

Dis-Armor Project

Dis-Armor is the newest in a series of psychocultural prosthetic equipment designed to meet the communicative need of the alienated, traumatized, and silenced residents of today’s cities. It connects contemporary research in two fields: wearable communi- cation technology and prosthetics. In doing so, it counters the dichotomy of the present explosion in communication technology and rampant cultural miscommunication. Dis-Armor offers an opportunity for indirect, mediated communication by allowing its users to speak through their backs. LCD screens, worn on the back, display live images of the wearer’s eyes transmitted from cameras installed in the helmet covering the face. A speaker positioned below the LCD screens amplifies the user’s voice. Attached to the helmet is a rearview mirror, alternatively, a rearview video camera, monitor, microphone, and headphone. These permit the user to see the face and hear the words of the spectator/interlocutor standing behind. Wireless video equipment installed in the helmet further allows two users to work in tandem, showing each other the other’s eyes and broadcasting to each the other’s voice.

The Vortex Chandelier

Le look du chandelier VorteXX est particulièrement futuriste, et a été décrit comme « une réminiscence de la double hélice avec l’apparence d’une forme fluide infinie, pulsant et luisant en apesanteur ». Cette lampe est fabriquée à partir de 60 moulages individuels et des tous derniers modules de LED permettant de générer de la lumière indirecte dans différentes teintes. Un système de gestion de la lumière imaginé par l’extra-terrestre le designer permet de programmer toutes sortes d’atmosphères lumineuses.
