Research 16: International Design Week Part 3 – Paper Collages and RISO

After the digital exploration of the topics, we used paper collaging on the last day. We worked quickly, making rough cutouts and thoughtfully combining them. We were instructed to cut everything beyond just the outline and to think out of the box. The exercise was also for us to work faster on developing ides and connecting visual material with out message without searching for the perfect image on the web for ages.

For the first collage, I created another version of the Faroe Islands topic. The teachers provided printed materials related to our topics, ensuring everyone found something useful. I also printed some of my previous slogans and typographic choices. Initially, I was very detailed and took a long time, but I soon got the hang of it and worked faster.

We combined all the black-and-white cutouts and roughly glued them onto white A3 paper. We then used these collages on the RISO. We scanned them directly to make masters and printed many copies of each design. During this process, Lars took some previously printed designs and overprinted them with another student’s design, which was not intended to be combined. This approach yielded very interesting results. Some elements matched well, as all the topics were problematic, and some slogans or images were reusable. In the end, we had one copy of the original design and nearly 200 different posters with various combinations.

My first work was for the topic of faroe islands and the whale hunting. This collage was an abstract visual showing a whale being stabbed. There are also some versions where it was combined with other designs randomly.

My final Design

I also made a collage for the pig farm topic and the AMA-Gütesiegel. I used their slogan and created a graphic symbolizing the pain pigs endure, featuring a cut-open pig and a brain functioning as its inner organs. This collage used 2-3 images per layer, unlike the first one, which was built from various cutouts. Unfortunately there was no original left of this design after the whole printing process. But there is a version with the AXI Draw in the end.

Lastly, I made a collage on the controversy of zoos. I found a fitting slogan and created a symbol combining human faces and barbed wire. On another layer, I used a zebra and cut out stripes from a different pattern to form a cage.

My final Design

As a final step, we used a tool called the AXI Draw, which can draw on top of printed materials. Some of us used it to rewrite slogans or add details on top of the layered RISO prints. This experimental approach was a refreshing change, allowing us to work more roughly and try new techniques.

This workflow was very inspiring and something new for me as you really have to trust also the process and it is something besides just looking in a screen the whole time. Also the RISO printing makes the end result more haptic and analog than if you just would scan the designs and rework it digital. So you get the overlay from the RISO with little happy accidents and it is way more authentic.

Research 15: International Design Week Part 2 – Digital Posters

Triggerwarning! If you don´t want to see maybe disturbing images of animals – please do not read this post further because I am using images from pigs which are in horrible conditions.

Concept 1: Pig Farms and Gütesiegel

My first design addresses the misleading information consumers receive through various certificates on products, combined with the frequent revelations of poor animal conditions on farms. These farms are often certified under the AMA-Gütesiegel. Despite numerous scandals, AMA claims these issues are beyond their responsibility, which clearly isn’t the case. The AMA-Gütesiegel does not propose better conditions than existing EU regulations; it simply aims to give consumers a false sense of security when buying Austrian meat. Although some farms are suspended from AMA, proper controls would prevent these issues from arising in the first place.

The first approach was to take their seal and rework the typography a litte bit to make it from Gütesiegel to Lügesiegel. Just a small detail thats powerful in its message.

With that I build two different designs for the poster. One is more graphic and the other one uses real life images. To highlight how two faced the campaign of AMA is, I decided to use AMA’s advertisement and rework it. I utilized their graphics, modified the text, and incorporated new images to achieve the desired effect. So here are my two versions for this topic – which the AMA Ad would be the chosen one of this for the presentation.

Concept 2: Whale Hunting on the Faroe Islands

The next topic I explored was whale hunting in the Faroe Islands, a cruel and unnecessary practice today. Pods of whales are chased to the shore with speed boats and brutally slaughtered. Despite no longer relying on whale meal, the practice continues with global buyers and some locals clinging to tradition. In 2023 alone, over 800 whales and dolphins were killed. Organizations like Sea Shepherd are on-site, documenting these events and try to stop it with petitions and more people are against it luckily.

Initially, I planned to create a modern travel poster-style design, but it felt too editorial. But the slogan „Welcome to the red sea“ stayed in my head. I shifted to a 50s-70s style inspired by Cassandre, known for his impressive posters. Due to time constraints, I couldn’t create my own illustrations, so I used Photoshop to edit images to fit this style. After much trial and error, I produced a compelling poster with interesting fonts. Here are my different versions for this topic.

Different approaches to this design style. First i edited the image heavily and then I played with the colors further and typography. On the first glance the blue/green version could look like a pretty image but then you see the details and what the bright red should symbolize.

This workflow showed my how individual the approaches can be to visualize such topics – you can use well known techniques and styles and use their main features to get a strong visual. That´s something that I will definitely be something I will explore further in this case. The next post will be about how I am using the same topics and also some same visual graphics in a completely different style and technique.

Calm Technology // 15

This week I tackled the problem of the power supply and decided to make a more polished prototype for it, as I do not expect any changes to this part of the project for the time being. This means that I want to enclose all the functional parts in housings and make it look like a normal power supply as used in household or consumer electronics.

Set-Up

To start with, I ordered a 240V to 12V transformer with a 2.5A output, which will give me a bit of headroom and also power the Wemos board. The rest of the set up consists of a textile power cord, some Arduinio wires, a plug, some shrink sleeves and my custom printed case for the transformer. As you can see in the picture below, there are two versions of my custom printed case. I would like to say it is an iteration, but it is because of a measurement error on my part and the first version is not usable. Which just goes to show that the old carpenter’s adage „measure twice, cut once“ also applies to 3D printing in rapid prototyping.

Parts

Assembly

I started by connecting the textile power cord to my custom case, and while the glue was drying on that end, I attached the plug to one side and the arduino wires for use in the breadboard to the other. I started by attaching the textile power cord to my custom housing, and while the glue was drying on that end, I attached the plug to one side and the arduino wires for use in the breadboard to the other. When that was done, I connected both ends of the cable to the transformer and fixed the transformer in its custom housing. The final result with the build together housing is shown in the picture below.

Connecting & Soldering
Final Outcome

Now that the power supply is finished, the setup for controlling both motors at full power is complete. The next step will be to build a rough functional prototype capable of generating the movements needed for Tap.

Exploring the Intersection of Voice and Health

A Review of „Vocal Musical Expression with a Tactile Resonating Device and Its Psychophysiological Effects.“ 1

In an intriguing study presented by Rébecca Kleinberger from the MIT Media Lab, the potential psychophysiological impacts of vocal practices are explored in the context of a multisensory installation named Vocal Vibrations. The study delves into whether specific vocal practices can influence one’s health by affecting mental and physical states.

The Experiment’s Core
The experiment took place in a setting called „the cocoon“, where participants engaged with music and vocalization while holding a device called „the orb“ that translates voice into tactile vibrations. This novel approach allowed participants to experience their voice in a unique, almost tangible manner. The study measured various physiological parameters, such as heart rate and electrodermal activity, alongside self-reported mental states to ascertain the impact of these vocal exercises.

Insightful Findings and Their Implications
One of the most captivating aspects of this study is its significant results, suggesting that certain vocal practices could indeed correlate with psychophysiological states when considering biographical data. For instance, participants who expressed a positive relationship with their voice tended to experience lower arousal levels during richer vocal practices. This insight not only opens new avenues in therapeutic practices but also underscores the potential of vocal exercises in enhancing mental well-being.

A Step Towards Holistic Health Approaches
This research emphasizes the need for a more holistic view of health, where vocal practices might play a role in managing or even improving certain health conditions. The connection between voice and physiological responses highlighted in the study could lead to innovative therapeutic tools that use voice as a central element.

A Few Considerations
While the study presents pioneering data, it also acknowledges the need for more extensive research to fully understand and utilize these findings. The sample size and the diversity of participants could be expanded in future studies to generalize the results more robustly.

Concluding Thoughts
Kleinberger’s work is a commendable step towards integrating voice-based practices into health and wellness regimens. It invites us to reconsider the potential of our voices not just as tools for communication but as instruments for health and well-being. As we advance, it’s clear that interdisciplinary approaches like this could be key to unlocking new forms of healing and self-exploration.

Overall, the paper not only contributes valuable insights into the intersection of acoustic science and health but also opens intriguing questions about how we might further harness the inherent power of our voices for better health outcomes.
