Macchina Poetica is a digital prototype converting sounds into onomatopoeic words and images and it’s inspired by the art of the Futurism movement.

Futurism is a modernist, avant-garde artistic movement originated in Italy in the early 20th century. Thanks to sound representation, Futurism artists aimed to emphasize speed, technology, youth and violence, all concepts arising from industrial innovations and war.

In order to keep continuity with this particular artistic movement, the authors, Alessandra Angelucci, Aris Dotti, Rebecca Guzzo, students at Master of Advanced Studies in Interaction Design SUPSI, decided to design an object that looks like the musical instrument of Futurism movement (precisely a Celesta). The object plays a metallic sounds and the user is facilitated in understanding how to use the object due to a instrument-like interface.

The machine is built using 4 piezo sensors, a thermal printer, a board, electrical cables, 4 resistors (1K), a 6 volt power supply and a Genuino Uno board.

The instrument’s interface is designed with plywood, metal plates and sponge that serves as a shock absorber. Between the metal plates and the sponge there are the piezo sensors along with resistors communicating with the Genuino Uno board every time the user interacts with the metallic plates. Once the Genuino receives the signal, it sends a command to the thermal printer that will print a word or a Futurism poem.

The interaction takes place when the user with the help of a metal tool (for example a screwdriver or a wrench) strikes the metal plates with different pressures. At the end of the performance the user and the viewers can have a clear overview of the produced sounds reviewing the printed paper outputs.

The prototype is the result of two weeks physical computing class Creating Tangible Interfaces held by Ubi De Feo at Maind program SUPSI  in Lugano, the goal of the course is how to make tangible interfaces via learning fundamentals of electronics prototyping and interaction design.  (Applications are open for the next edition 2016/2017 starting in September 2016)

Stellar is an interactive installation by sound artist Francesco Fabris, which aims to create a sonic representation of stars and constellations through a dedicated interface.

The project has been developed using two Arduino Uno, LeapMotion and Max7 software managing data of more than 300 stars and 44 constellations, stored from the open-source software Stellarium, and coded to interact with the robotic arms.

One Arduino Uno board controls four servo motors and a second one controls the led stripes. The motors are controlled with two LeapMotion but since LeapMotion doesn’t support two devices on one computer, he used two miniMac  connected through an Ethernet network.

Since there’s no sound in space, Francesco wanted  to conceptualize a link between electromagnetic and sound waves  to create a minimalistic, interactive device which would allow visitors to learn about specific stars through sound information:

The base of the system is a cylindrical structure, on top of which are displayed the most important constellations of the northern sky. Above this representation are two robotic arms. When the tip of one of the arms aligns with a star, information on the selected star is transformed into simple sine waves, changing the colour the star emanates.

Two players can use the system at the same time, by moving their right hands over the two black, circular sensors. This allows them to move the robotic arm both horizontally and vertically.
The data analyzed for each star are: temperature (color index: red star = old and cold, blue star = hot and young), brightness (as seen from Earth), distance (from Earth) respectively transformed into: frequency (Hz), amplitude (dB), duration (ms).
The colder the star, the lower the pitch; the brighter it appears to us from Earth, the louder the sound; the further from Earth, the longer the duration.
For example, a bright, red star four thousands light years from the Earth would generate a low frequency, loud and long sound. A blue star which is closer to the Earth would generate a high frequency, weaker and shorter sound.

The background drone-sound is white noise (which is a combination of all frequencies, the opposite of space-silence). When a constellation is triggered, the number representing its area (squared degrees), becomes the cutoff frequency of a low-pass filter for the noise signal. In this way, larger constellations will gradually increase their frequency.

Don’t miss the “Making of” video:

Stellar has been produced with the support of the DE.MO./MOVIN’UP I Session 2015 project, and promoted by the Ministry of Cultural Heritage & Activities & Tourism, General Directorate for Contemporary Art, Architecture and Urban Suburbs and GAI – Association for the Circuit of the Young Italian Artists.

“Data transparency” is a project by Jiayu Liu, a designer and media artist, interested in physical data visualisation and interactive code. The installation runs on Arduino Mega: when the microphone senses a person’s blow, it transforms it in a Led animation and then activates the bubble machine for 8 seconds. The project is not aiming to visualize any specific data but “data visualization” itself:

In my point of view, data is not dissimilar to a conclusion of our past, and we need it for our future. When we see a data from a computer, it is something that has already happened. We use intelligent methods of computing science to analyze the data so that to predict the future. We are living in a world of data, and data is like a language objectively describing our past. In this work, I take more attention on rethinking and recalibrating the role of data in our lives, and the relationship between the virtual world we build as a main method of data storing, analyzing and visualization and ourselves.

Also, I am thinking of that it is better to make sense of the role of data visualization before really visualizing it. Finally, I found a good perspective to see how data connects with our lives, which is Time.
Therefore, the project is not aiming to visualize any specific data but what I am trying to visualize is the “data visualization” itself. I would like to bring a new experience to the viewer in different space. So I want to create a interesting play space and bubble game to the viewer . Let them have a really funny and relaxing experience.

Take a look at the “making of” video below to see it in action:

Wing is an interactive installation created by Dmitry Morozov  and commissioned by the Center for Art and Media (ZKM) in Karlsruhe, special for GLOBALE: Exo-Evolution exhibition, 2015. It’s a 2,5-meter wing that can be flapped by visitors thanks to compact dermal myLeaographic sensors (sensors measuring the electrical potential of muscles) installed  behind their ears and connected to an Arduino Uno:

The main idea of the project is an ironical and at the same time serious research on the topic of development of new instruments and prostheses as “extensions” of human body and accordingly its possibilities and potentials, which are being revealed by new technologies. At the same time, it’s an attempt to stimulate people to perceive and train the body in a different way, expanding the limits of self-control and self-organisation in order to adapt to the new conditions. At the same time, just like many spiritual practices aiming at the elevation of human soul through deep relaxation and control over seemingly uncontrollable muscles, this project uses the metaphor of flying as a reward for the ability to direct your mind to solving of non-standard tasks.

During the Physical Computing and Creative Coding course at School of Form a team composed by Ernest Warzocha, Jakub Wilczewski, Maciej Zelaznowski worked on a project starting from the keyword “the aesthetics of interaction”. With the help of their lecturers – Wies?aw Bartkowski and Krzysztof Golinski – they decided to rethink about typical button-like interface of audio sequencer and design a unique tangible interface for it.

The Wooden Sequencer runs on Arduino Uno and works by using familiarity of real objects and manipulating them similarly to the idea of Durell Bishop’s Marble Answering Machine:

Instead of regular buttons we created wooden discs (4×8 circles) that placed in holes generate audio sequence. Each line corresponds to different instrument and columns are responsible for time when sample is played. To know in which point at timeline our sequence plays there is hidden LED on top of each column that blink through wood and informs user which one is currently played.

To create good-looking round shapes of table we used CNC router at our university. After the milling process we connected all electronics with table and sensors for each hole. The core of our project is Arduino UNO with multiplexers and MP3 module. With rendered samples and build-in speakers our project doesn’t require computer plugged in.

Important and somehow unique in our sequencer is usage of IR reflective sensors to change played instrument sample. To decide which sample we want to play sensor recognizes different grayscale color and intensity of the reflected light at bottom of our discs – actually everything placed on table can generate sound. Creating grayscale-based controller is experimental way to interact with device. Furthermore, using grayscale palette might be great idea for MIDI instrument. For this project we used two colors to show the concept. It’s possible to add more but it’s more sensitive to non-constant background light.

Take a look at the video below and explore more pictures on Behance:

“The color Visualizer” is an immersive installation to understand how color is used in nature to communicate between living organisms and to explore biodiversity through the lens of color:

By plucking an array of multi-colored strings, which are layered over the large array of high resolution screens, visitors can explore over 100 unique color stories as vibrant images and short videos appear before them. Strum a red cord, for example, and learn how a male cardinal bird colors his vibrant red feathers with pigments from food; strum a yellow cord and see how a yellow leopard’s spotted coat allows this predator to blend in with shadow and light while moving through tall grass.

The eye-catching cylindrical installation is part of the permanent exhibition “The color of Life” that opened in June 2015 and was created by Tellart in collaboration with the California Academy of Sciences. It was prototyped using Arduino Uno and it’s currently shortlisted for the Interaction Awards, representing excellence in interaction design.

In the video below the team working at the project explain the main features of the educational installation and show a bit of the making of:

Get inspired by a sneak peek of the topics:

Truly multi-platform

Great user experiences don’t only happen on the web or in apps. Users live in a world that gets richer day by day where they face different devices, operating systems, wearables, online services, interactive terminals and media installations. They don’t look at your product in an isolated way—and you shouldn’t either when designing it. At push.conference you will meet designers and developers of outstanding digital products on all platforms.

The Internet of Things is finally happening

While we amuse ourselves laughing about the connected fridge, IoT has arrived everywhere around us. The idea of omnipresent connected devices is stronger than ever before and hitting the product lines of startups like Nest as well as those of established players like Apple, Bosch and Siemens. Simone Rebaudengo, speculative interaction designer at frog, and mobile platform expert and author Josh Clark, share with you where this is heading and how we must prepare our products to be ready to succeed in the global networked ecosystem of tomorrow.

Psychology enables even more personal interactions

User research is a great basis to define requirements and directions for services and interfaces. Turning insights into the actual features in an interface is however not always so simple. That’s when understanding how emotions and psychology influence our users comes into play. Experience researcher Pamela Pavliscak and founder of UI-patterns.com Anders Toxboe will share their strategies when it comes to harnessing the power of happiness and persuasive UI patterns to create emotional reponses, help make decisions and guide our users.

Process shapes product

With iterative design and lean mindsets, prototyping has become an essential skill in our design process. Heather Daggett, Sr. experience design prototyper at Intuit, will cover when and with which fidelity prototypes inspire or help make decisions, and give advice to designers that face the decision how much of their energy to invest into technology skills.

Rich experiences

As important as a good concept is, it is the actual pixels on a screen that users will see and interact with. Making complex information accessible with interactive visualisations is the expertise of Audrée Lapierre of Montreal based studio FFunction. Dustin Senos, former Head of Design at Medium.com will explain how delightful details and a contextual interface make for a great experience beyond reading content on the web. Finally, we live and design in an age where dynamic use of space inspires interaction design from Google’s Material Design to the first ripples of virtual reality. Preparing for this, motion designer Pasquale d’Silva will propose to us a new approach for structuring multidimensional interfaces.

 

Originally from Guatemala, Balam Soto is an artist and maker of software and hardware creating interactive art installations and public artworks that fuse low tech with high tech. He recently shared with us a project called Exp.Inst.Rain and running on Arduino Uno:

” Exp.Inst.Rain” is an interactive installation and experimental instrument that incorporates projection and sound generated by a wireless box made of wood, plexiglas, Arduino, electronic components and custom touch sensors. By touching the box at various points, participants create different sounds; these sounds then generate changes in the projection.

It is an analysis of the social and cultural adoption of tangible user interface. Globally, touch devices are increasingly common; people understand how to use them. “Exp.Inst.Rain” analyses this new technology and makes use of this new common understanding to fuse sound and visuals into realtime interactivity.

This artworks it’s power by Arduino and wireless vibes , using Capacitive Touch Sensor and home made aluminum electrode to pick up touch. Custom software acts as a Bridge between the Exp.inst.X and Midi software.

Julian Hespenheide is an interaction designer based in Germany who submitted to Arduino blogpost a writing machine called émile. It’s an interactive installation created in collaboration with Irena Kukric, David Beermann, Jasna Dimitrovskais and using Baudot code - a binary 5-bit code, predecessor of ASCII and EBCDID – intended for telecommunication and electronic devices, representing the entire alphabet.

It runs on Arduino Uno and  translates the bauds (/?b??d/, unit symbol Bd) into moving objects that are being sent over physical tracks in order to illustrate  a simple computational process of 5-bit binary information transmission:

The machine was built in six days with four people. In our group we came to the conclusion, that not every process in a computer is really transparent and it already starts when you type a simple letter on a keyboard. To unwrap this “black box” of data transmission, we set our goal to build a small writing machine where you can literally see bits rolling around. After some research we got back to the beginnings of Telefax machines and data transmission using Baudot-code. We then quickly designed punchcards and mapped them to a slightly altered baudot code table and cut them with a laser cutter from 5mm plywood.
Whenever a marble hits a switch, a short timer goes off and waits for input on the other switches. If no other marbles are hitting those switches, we finally translate the switches that have been hit into the corresponding letter.

Take a look at the machine in action:

Every year the students of the Copenhagen Institute of Interaction Design (CIID) attend the Physical Computing class as part of their curriculum.

Having a small delegation of the Arduino team teaching this class has become quite a ritual. This past March Ubi De Feo, Alice Pintus, and Lorenzo Romagnoli runned the two-weeks-long intensive class.

Teaching at CIID is great experience, since you are surrounded by incredibly motivated and curious students, that are doing everything possible to design amazing projects and prototypes.

The topic of this year was prototyping interactive installations for a Science Center that would explain in a playful and engaging way how a technology works. For most of the students this was the first experience with physical computing, but even in such short time they were able to build eight different prototypes. The projects explain in an interactive way the science behind computer viruses, allergies, video compression, machine learning, laser printing, digital music synthesis, binary numbers and neuroprosthetic.

In Explaining laser printing Victoria Hammel, Chelsey Wickmark, Ciaràn Duffy, Feild Craddock demonstrate how the laser printer works. By using 16 servomotors connected to an Arduino UNO to move a matrix of magnets they were able to attract iron filings and draw letters on paper.

In Troyan 77 Karan Chaitanya Mudgal, Liliana Lambriev, Gunes Kantaroglu, Dhruv Saxena visualize the effects of a Trojan Virus harming your computer. Connecting Processing to Arduino they were able to create an overlay projection on top of the maze representative of the effect of the viruses on a computer.

Sound Blocks by John Ferreira, Alejandra Molina and Andreas Refsgaard is an musical instrument that explain how to compose sounds combining multiple soundwaves. The prototype was built using Arduino as a midi controller for Ableton.
