Week 4: Research Project (Rudi) – Kennedy

 Research Project

I agree with the Merriam Webster dictionary’s definition of interaction; it is described as “mutual or reciprocal action or response”. This definition is broad enough to apply to the entire “spectrum of interactivity” as mentioned by Chris Crawford in his book The Art of Interactive Design. However, a common issue that I have found was that the interactivity of everyday objects seem to score very low on the interactivity scale. Those that are considered to have a “high” level of interactivity were very limited in terms of everyday use. I would like to see more devices that do not interrupt our daily lives but integrate themselves naturally.

Our project was bred out of the idea that we’d like to have users be seamlessly integrated with their environment wherever they are. Thus the wrist bands were born. The bands do not obstruct your immediate surroundings and do not require troublesome input or output devices. As a wearable device, it is portable and convenient for all users. In addition to the environment, users can also interact with other people. This aspect was very important for us as a group because many devices seemed to primarily cater to long distance online communication. If there was a way to facilitate better in person communication society would see benefits in communal living and overall feeling.

Using the basic hand gestures seemed very useful given that they do not require a shared language. A new user could receive this device and understand the general implications of each gesture. This concept is similar to how sign language works so, just as how sign language continuously develops and grows the gesture database could also.

The interactice project I did not like was an interactive store front advertisement by Starbucks (https://creators.vice.com/en_us/article/mg9xxx/interactive-gesture-controlled-starbucks-storefront). The advertisement was clever enough where casual passersby could stop and “make” their own Tzao Tea. Users would do this by dragging ingredients together via sensors and a large animated interface. This advert seems entertaining but, I did not like how it ripped people out of their immediate surroundings. It acted as a portal to a hyper commercialized game arcade for users to be lured into. It comes across as a cheap marketing ploy to drive sales and conversion. I wish there were more layers or some level of depth into this device.


A project that I found interesting was a wearable prosthetic that detects air pollution (https://creators.vice.com/en_us/article/8qvxmb/wearable-prosthetic-detects-air-pollution). This project included a detailed explanation of how the device worked and also its intention. It’s literal function is to instill the “flehmen response” into humans. The “flehmen response” is an animal’s natural reaction, curling back of the top tip, to smelling toxic chemicals in the air. By simulating this reaction, the artist hopes to create a similar natural response in humans to pollution over many years of evolution. This idea sounds ludacris however, the artist’s message is what I find very interesting. She looked at the an issue plaguing our world today and presented her own satirical commentary. While intricate in design, the device’s primary function is to have people realize how severe environmental degradation has gotten. This is the type of projects I strive to produce in the future.


Week 3: Sensors (Rudi) – Kennedy

Circuit #1: Infrared Distance Sensor


Bread Board


Micro Servo 90 – the motor used the 5V power source to spin in a clockwise direction (given the particular flow used)

Infrared Sensor – detected objects in front by sending out a infrared light and receiving how much was able to bounce back to the sensor.

This circuit was fairly simple to put together. We did have some problems with the motor not rotating at times; however, we are pretty sure that was due to overheating. To fix the problem we unplugged the arduino from the power source and waited a bit. Next test the motor seemed to work.



What did you intend to assemble in the recitation exercise? If your sensor/actuator combination were to be used for pragmatic purposes, who would use it, why would they use it, and how could it be used?

We created a circuit using both a 130 Motor and an infrared distance sensor. I liked the idea of using an infrared distance sensor because it was something very simple and could be used to make everyday devices such as automatic doors. Our particular device could be used in conjunction with the fan blade attached to the motor to make an automatic cooling station. Events such as sports games can get extremely hot when the sun is beaming and there is no breeze; therefore, our motor and sensor combination could act as a device to cool down spectators in a crowded arena. This would be beneficial because it would prevent the waste of electricity by only turning on when there are people in front of the sensor.

Can you identify your circuit with any device you interact with in your daily life? How might your circuit be used to have a meaningful interaction?

As stated before, the infrared sensor could be used in automatic sliding doors. Another example is the lights usually found in garages. These light only turn on when it senses an object in front. This prevents the garage light from staying on all night while also making it easier for people to find their way at night.

The circuit we built could be used as a monitor for users to interact with. For example, if the blades of the fan has LEDs on them they could spin fast enough that an image is produced. The sensor would prevent excess energy use and user addiction by having strict limits of use (the sensor must detect the user in front at a certain distance). We could use this “screen” to video chat with friends or engage in digital communal activities.

How is code similar to following a recipe or tutorial?

Each line of code gives a specific set of instructions. The arduino interface uses C to tell it’s components what to do; this particular language requires the programmer to identify the exact data type thus, giving the code even more detail. This further solidifies the idea that code is very similar to a recipe. I think tutorials are primarily narrow minded and too specific. They give a set of actions that produce a specific result. In contrast, the same recipe may not always produce the same result. You can use the same recipe to make your mother’s chocolate cake but it will never taste exactly like her’s. You may have added a smidge more of sugar and a bit less of chocolate so it came out different but, in the end it is still a chocolate cake. Coding is similar in that you can follow the same logic, have slightly different code, and produce various results. In the end you still have some input that produces some output.

In Language of New Media, Manovich describes the influence of computers on new media. In what ways do you believe the computer influences our human behaviors?

I think that computers have forced humans to reevaluate the concept of intellect. Before computers humans were compared to humans. The moment the first computer was faster than the human brain we have had to rethink what it meant to be smart. I think that a different but similar phenomenon will happen in the coming years. We will soon have to completely rework what we think it means to have creativity. There are currently computers that seamlessly work through intricate algorithms to produce great sums of data but there are also computers who work though their own algorithms to produce pieces of art. The introduction of computers capable of creativity will create a revolution with every creative field just as computers with high computing power did to tech, business, and education.

Week 2: Arduino Basics (Rudi) – Kennedy Cambra-Cho

General Components:

Arduino – is a programmable microcontroller board that

Breadboard – allows circuits to be easily assembled for prototyping by forgoing soldering

Jumper cables – connects elements of a circuit to be connected over a larger area of space making it more comprehensible and easier to patch

Circuit #1: Fade


Resistor – metal wire that restricts the flow of the current

LED (Light Emitting Diode) – emits light at different intensities according to the program

From this first circuit I noticed the importance to attention to detail when working between the breadboard and the arduino uno. Simply placing jumper cables in the wrong port on the arduino can sometimes cause unnecessary extra work.


Circuit #2: toneMelody


Speaker/buzzer – emits a buzzer sound at different pitches according to the program

I enjoyed building this circuit but I found figuring out the program was much more entertaining. Once we got the hang of how the numbers affected the pitch of the buzzer you can make almost any tune.


Circuit #3: Your Choice


Resistor – metal wire that restricts the flow of the current

Button – input device used to send the pattern back to the program

LED (Light Emitting Diode) – emits light at different intensities according to the program

Speaker/buzzer – emits a buzzer sound when the program begins and also when the wrong input is entered

  This circuit made me wish we had a larger breadboard. Everything seemed crammed even when we tried to plan ahead and keep the jump cables out of the way of buttons. With the various components involved it was much harder to assemble and to fix when problems would arise. Simply pulling out chords and replacing them became an troublesome task. Overall this circuit was interesting and did work in the end but I think a second attempt may prove more successful.



Reflect on different interactions with technologies that you have observed in your daily life. Pick a few of these and write down your own definition of interaction based on your observations.

Two devices that I interact with everyday are the turnstiles in the metro station and my cellphone. The latter attempts to act as a “highly interactive” device while the former would be considered very low level on the interactivity scale. Using cell phone features such as Siri which try to respond semi-independently to user’s prompts show what “interactivity” is trying to achieve. However, along the way we have devices such as the turnstiles; they simply respond to user’s interaction based on a rigid set of rules. Despite their simplicity I do think their response is valid. By allowing you through they send the silent signal that your metrocard has a positive balance. I think that the word “interactive” means the pass of information between two players. This is shown by both devices while at different levels of interactivity.

During the assembly of the circuits, we used many electronic components as inputs and outputs. Which of these components do you recognize in the circuit?

Buttons were used as electronic inputs for the Zelda Simon Says circuit. They allowed the user to enter the pattern visualized by the LED which acted as electronic outputs. These two components acted similar to the keyboard and screen on a computer. Users pressed buttons to enter information for the program to read and respond accordingly with the visual output of the LED.  

If you have 100000 LEDs of any brightness and color at your disposal, what would you make and where would you put it?

If I had 100000 LEDs I would build a model of another solar system and I would hang it from the ceiling in my room. I’d choose to do this because I like the idea of reworking classic childhood projects. It would give me a chance to work with something familiar and new at the same time.

Which reflections about the nature of interaction can you make about the Figure I.1 in the Physical Computing reading?


Through this image we can infer that “interacting” with something requires one or more of the five senses. The technology around us only recognize the active participants in our “communication” thus, body parts such as eyes, ears, and fingers act as primary outputs and inputs. From this image I feel that our interaction with technology has been very limited. In order, to expand the levels of engagement with technology I feel that it is worthwhile studying how those with physical disabilities interact with tech. By studying how people compensate for missing sensory inputs or outputs I think that we can find more innovative engagement practices.
