Last spring semester I develop I project called Please Do Disturb. Please do disturb is a social experiment, a community based project that aims to encourage social interaction in the context of a building. How many neighbors do you know in the building where you live ? do you interact with them ? The idea of this project came from the "Please don't disturb sign" that normally we see in hostels and subvert it's meaning by creating a visual system that invite people to disturb. I thought that the perfect place for this to occur is a building. Shared by so many people that don't know each other or if do, don't say more than a "Hi!" or " Bye!" .Instead of using the signs posted in the door of each apartment, the idea is that each person when wanted to be disturb, should post a sign in the mailboxes. The mailboxes acts as a "shortcut" for the door, since it is visible to all the persons that lived and that entered in the building. At the time, I design it to be used as stickers (paper) that you put on the mailboxes but I got some critics about the usability of the system. So I want to try to do the same project but with cellphones. Not sure yet if it only SMS or if with MMS. I think that in beginning I'll try to developed it only using sms! Registration: 1. User subscribe online (forms - name, username, phonenumber) 2. Data get store into a DataBase 3. User get a sms on the phone with confirmation message +reminder of email address(for now) he should used to send msg.\ App: 1.User sends via phone notification to be disturb. ( pre/define actions?) 2.Message is store - database ( msg,user, timestamp) 3. User get confirmation msg. 3. Message is broadcasts to other users Questions: What happens when the user wants to reply to a notification? Does the system allows communication btw users or not? Is it just a "notification system or a channel(forum) for communication? 2. Collection of images from the sky. I think that will be very beautiful if people can send pictures or videos (loop's of 30's) of the sky and see a collage of several skies. Questions: Is it just a one way communication? Users just have access to data via a website? What motivate a user to interact and participate? How they will be display? Sequential? or by location? Registration > same system App: 1. user sends image or video 2. get store into a folder and maybe database ( name + time + location) 3. User get sms > "your image/video was received" 4. Image is added to the website 3. City - Public Health - Creating awareness about the amount of trash Since I arrived to NY that is something that completely disgusts me and perturbs me in relation with public health. With the amount of restaurants that the city has and other services, is true, the amount of trash that is created is enormous. I would like to create an application where users can send situations that they think that are dangerous for public health in the city. Trash is one of those situations. The idea is that images are collected from users and somehow voted by all users in order to do really something when one of those situations is so outrageous that something more effective needs to be done, but only when there is agreement by the majority of the community. Still need to think more about this and about the system but the idea behind it is that sometimes we, humans, complain about stuff and we don't agree with a lot of things that are happening on the planet but barely we take any serious action. So when the community of users agree that some deserves to take it further the system itself takes the initiative and for example, fill a complain to an nyc organization that is responsible or call a complain number...take a more drastic attitude - encourage by it's users but doing the "service for them" as a collective action. Question: define better which situation, the mechanism for voting and the complain part. Today I was talking with Diego about it and he is also interesting in exploring this topic. He talked about using the location factor as the one that triggers the automatic action and not the users voting. Once the system starts to see that several pictures are taken in the same location, quarter it means that that area in a alert situation. I think it's an interesting idea. Tomorrow we are going to try to work better in this idea. ]]> http://www.prntscreen.net/itpblog/2009/02/project-1-ideas.html http://www.prntscreen.net/itpblog/2009/02/project-1-ideas.html Fri, 06 Feb 2009 11:46:25 -0500 Performing two Google searches from a desktop computer can generate about the same amount of carbon dioxide as boiling a kettle for a cup of tea, according to new research. Electricity consumption and greenhouse gas emissions caused by computers are an issue that is provoking concern. IT industry generated as much greenhouse gas as the world's airlines - about 2% of global CO2 emissions. A search in google originates requests in more that one server. It goes to several competing against each other. The system minimizes delays but raises energy consumption. Servers, files, computers, networks, infrastructures...But what is better to be online or watching tv? to be online or driving? Maybe a more active way of being is better that a more passive, no? and about paper? and newspaper carbon footprint? so now we have to turn the web green also? didn't google did that when it was possible to see google in black? ( i don't know if it was google or a mac option....) or why we don't go back in time and use the web as was before...just text, less colors, no animation... why we don't use Mosaic 1.0 again? ]]> http://www.prntscreen.net/itpblog/2009/01/google_searchs_carbon_footprin.html http://www.prntscreen.net/itpblog/2009/01/google_searchs_carbon_footprin.html Tue, 13 Jan 2009 23:13:20 -0500 2. Messages are separated from the visual node itself. Each color is a button that when pressed sends it's color to the other node. The nodes are represented by an input and output areas. When a node receives a color message it changes it's input area/zone according with the color that is send. ]]> http://www.prntscreen.net/itpblog/2008/12/final_project_phase_1.html http://www.prntscreen.net/itpblog/2008/12/final_project_phase_1.html Creative Networking Wed, 03 Dec 2008 19:32:24 -0500 Technology: Using processing and the Network Library, the application simulates the physical network. The physical network consists on multiple nodes that are able to receive and send messages - voice messages. Each device has a microphone( send - output and a speaker ( receive - input ). The rules that defines the communication between devices is that: - Each node can send a message at will. - The device can only send a message to one of the devices that are active (on the network), and from that devices it excludes the device that had previously send a message to this device. When define and build the simulation I start having some problems in relation with setting up a network under the nyu domain and in figuring out how to send sound over a computer network. To simplify, I decided that instead of sending sound I should instead send data that the nodes can send - color. In conclusion, the simulation will consist on setting up a physical network where each computer is a node( client program) in the network that "talks" with other nodes via a server ( another program) that "observe" and visualize the activity on the network. Each node can send ( at free will - free speech) one from five colors that are available. It can send how many messages it want but it has to follow one rule: if it receive as an input message a specific color it has to send that color back to the network. The colors work as a metaphor for messages ( voice messages). Each color "means" a common message. When one device receive for example a blue and responds with a blue, it means that it is responding to that message, to the context of that message. The idea is to see - having the server as the observer - how long it takes to get all nodes sending the same color over and over. This is the first step of trying to make a working prototype but my final aim is to put this network working with sound - input from the computer microphone. After trying to solve the initial problem I found that if the computers connected via a LAN using a router they can also shared a folder where the sound files are stored and could be access by all nodes. Maybe it will not be so real-time as I wished but it's a solution.]]> http://www.prntscreen.net/itpblog/2008/12/final_project_babel_tree.html http://www.prntscreen.net/itpblog/2008/12/final_project_babel_tree.html Creative Networking Wed, 03 Dec 2008 17:57:40 -0500 RumblePhones consist of a pair of noise canceling -20 Db ear protecting headphones, two microphones, two vibration motors, an amplification circuit, and an Arduino Microcontroller. The microphones, mounted on the headphones themselves, will pick up sounds from the surrounding environment, and feed this data, after amplification, to the Arduino as an analog value. This value will be used to control the speed of two vibrating motors, mounted in the cups of the headphones themselves. This process translates the sounds of the surrounding environment into vibrations felt on the ear of the user. After putting the device's headphones on, the user will be invited to walk around the area the project is displayed, experiencing the sounds of their environment as vibration. A potentiometer on the RumblePhones will allow the user to adjust their sensitivity, allowing the translation of sound to vibration to be clear even in a loud environment. The Parabolic Hand Mics consist of two small, directional, parabolic mics, to be placed in the users hands. The output from these microphones will be run through two sensitive amplification circuits, each with an independent volume adjustment, and then fed to a pair of headphones. The mic held in the left hand will be tied to the left channel of the headphones, and the one in the right hand to the right channel. The mics will, in a sense, become the users "ears", and moving them about will alter what they hear, and the direction that they hear from. This experience should be evocative of how animals that can move their ear cups, such as cats or rabbits, perceive sound.]]> http://www.prntscreen.net/itpblog/2008/12/final_project_technology.html http://www.prntscreen.net/itpblog/2008/12/final_project_technology.html Rest of You Wed, 03 Dec 2008 17:32:49 -0500 Devices for Altering Aural Perception consist on a group of devices that are designed to change the way the user perceives sonic environments and the city. This project aims to be an exploration/research in human perception, specifically in the way that we perceive the sonic environments that surround us on a daily basis. How could that perception be augmented or translated to offer us a different experience/sense "of reality". What if we could experience the city from a (non-human) animal perspective? What do they experience? Can we experience/sense the city as they do? keywords: senses, sound, perception, synaesthesia, physical computing, animals vs humans Motivation: This project comes from a shared interest in the differences between human and animal perception, synaesthetic experiences, and sound. We aimed to create simple, discreet, and wearable devices capable of allowing the user to reexamine and explore everyday acoustic environments in new and interesting ways. User Scenario: After putting on the devices, and adjusting their sensitivity, users will be encouraged to explore the sonic environment that surrounds them.]]> http://www.prntscreen.net/itpblog/2008/12/final_project_devices_for_alte.html http://www.prntscreen.net/itpblog/2008/12/final_project_devices_for_alte.html Rest of You Wed, 03 Dec 2008 17:31:35 -0500 Arduino Mini 04 schematic: link 1 + link 2 ]]> http://www.prntscreen.net/itpblog/2008/11/arduino_mini.html http://www.prntscreen.net/itpblog/2008/11/arduino_mini.html Rest of You Fri, 21 Nov 2008 20:18:10 -0500 Process: a message is send to nodes When the msg is sended: user chooses each node is starting to send the msg - mousePressed Visual Feedback- send msg: the node bumps - like it's emitting something Visual Feedback- received msg: the node bumps - like it's receiving something Fully Connected: send a message by clicking in on of the nodes.

Connect the Bluetooth to the FTDI or to the arduino through RX and TX ( this way is just easy to give power to the bluetooth 2. On the MAC, go to bluetooth ( normally there is an icon on the top bar) and make sure that work computer is discoverable - that your bluetooth is on 3. Choose "Set up a Bluetooth device" > Any device. It will start searching! 4. Meanwhile ( depending on the kind of bluetooth smirf that u have) click on Passkey Options and choose " Do not use a passkey with this device" or if u have a passkey just entered it 5. Selected the device > Sparkfun-BT ( normally that's the name that appear's) 6. Click continue 7. It will establish the connection btw them. Close window 8. On the same bluetooth icon choose > Open bluetooth preferences 9. Click the Sparkfun-BT > Edit Serial ports in case that you want to rename the port that you are using 10. Voila!!! If you are sending data from arduino through Bluetooth to Processing to do something with that data just use the same methods and procedures that when using serial communication btw Arduino and Processing. Just choose the correct port, using the port that you created in the steps before and not the usb port. ]]> http://www.prntscreen.net/itpblog/2008/10/bluetooth_macs_serial.html http://www.prntscreen.net/itpblog/2008/10/bluetooth_macs_serial.html Rest of You Sat, 11 Oct 2008 22:55:14 -0500 ]]> http://www.prntscreen.net/itpblog/2008/10/dont_forget_voltage_regulators.html http://www.prntscreen.net/itpblog/2008/10/dont_forget_voltage_regulators.html Rest of You Sat, 11 Oct 2008 22:15:59 -0500 Twitter Network: It's not so easy to define clusters since there are persons that belong to several clusters at the same time and trying to define their proximity to one instead of another had to be a decision. In this network I found 4 big clusters: itp alumni + itp students + algorithm scene ( hard also to name this clusters - maybe " idols") + portugal ( mix communities). Also there were some persons that doesn't fit any cluster. One important conclusion that I can take from this visualization is that media art organizations/institutes/groups ( most of them based in NY) are not interconnected, so they don't form a strong cluster or in other words, a big community! links: Graph ML | Applet Delicious Network: I don't use del.ici.ous for a long time.

Sensing the difference in light using a Photocell I started thinking that this idea will produce amazing results. There are so many changes in light through out a day. We "use" so many difference spaces that have very distinct lights. Could be possible to map all that changes? what visualization it will produce? Will be possible to understand the spaces? I'm thinking of creating a necklace made of conductive thread that has a photocell in the front (kyveli's style) and that is connected to an arduino with a bluetooth. The idea is to have later the bluetooth sending the data to a cellphone that collects the data. 2. Sensing electromagnetic radiation as the " new pollution" I'm very fascinated by ElectroMagnetic Radiation and how it is possible to turn this data visible or real ( sensed). There are plenty of projects working with EM but it's something that I would like to play with and experiment. My idea is to create a bracelet that senses through vibration or light ( I think I prefer vibration) the EM radiation that surround us and that "can or not" affect our body. One thing that I noticed in some projects already done is that in order to capture this radiations the devices need to be very close to the "object" / device that is trying to capture them. I would like to explore how can this be improved, if possible!!! 3. Sensing distance - Proxemics According with Edward T. Hall, proxemics is the study of humankind's "perception and use of space". Is the study of how people interact in relation to their physical environment and each other. Hall identified four body distances as key points in human spacing behavior: - intimate (0 to 18 inches) ( 0.5,m) - personal (1.5 to 4 feet) ( 1.2m) - social (4 to 10 feet) (3m) - public (10 feet and beyond). I'm interested in mapping this distances through time and do some research about proxemics, since I am interested in understanding better how social interactions in public spaces work. Communication is profoundly affected by the choice of space and by how different bodies inhabit that space. According with Hall theory, the idea of personal space varies and changes with different cultures. I experienced that difference when I moved to New York. I still feel the difference today and even if I changed my behavior somehow it's so natural that sometimes it happens and I feel embarrassed and strange but happy inside to still be and act that way!! As an example, there is a project developed at ITP - Urban Sonar --- --- ---- Sensing: Light / ElectronicMagnetic Radiation / Body Distances How: wearable devices Power: Arduino Pro Mini + Bluetooth = 3.3V min (cell baterries) or 6V batteries with normal arduino Store: for these ideas I'm thinking of using a arduino to sense/collect data with a bluetooth that is sending the data to a cellphone that later could be send to a computer or website. ]]> http://www.prntscreen.net/itpblog/2008/10/week_4_environmental_logger.html http://www.prntscreen.net/itpblog/2008/10/week_4_environmental_logger.html Rest of You Wed, 01 Oct 2008 15:58:05 -0500
