Interaction Observations

Gym equipment

I hate cardio equipment but I have been exposed to it enough to have some assumptions about how it’s used. I thought their use would be interesting to observe because while I have a friend who literally train for marathons on treadmills and just watches TV, I’d never do either of these things even though I did track in high school and go running all the time. Anyway: I assumed most people would take advantage of these giant screens that are now installed to listen to music or watch T.V. or plan their workout. I figured my marathoner friend was an anomaly and probably most people would get bored after about 30 minutes.

I picked my own cardio spot with a good view of everyone’s screens and was surprised that multiple people had what looked like a track on their screens. Like simulating a track environment? I didn’t even realize this setting existed. No one was watching TV and some people were listening to music straight from their phones. A lot of people use this equipment just for walking, which seems SO boring. The walkers also spend the longest time on treadmills! I was just confused because it seems much more pleasant to me to walk around in normal clothing outside. People just starting out usually went with quick start and then checked out other options, or knew something specific they were after (a workout on the ‘track’) and did that.

I had a small sample of people that I observed, but everyone fell into a low-intensity category playing with their phone, or an intense-workout category where they were not really using other entertainment. Time spent on machine varied but maybe on average I had it right around 30 minutes. It was interesting to consider the Norman and Crawford readings because it seemed like there was a lot of functionality built into these entertainment monitors, but people weren’t really interested in most of the options.

The dishwasher at ITP

I just have to note that the system of signifiers (washing, dirty, clean) on the dishwasher must present a design opportunity, because the dishwasher clearly isn’t communicating its state. I also know I am not the only one who has opened the dishwasher while it was washing, because someone did not move the magnet to the washing square. One of my classmates the other day, after I opened it and noticed it was hot, joked “You are a human sensor.”

Digital In/Out & Analog In labs

This week we learned to read input from switches, variable resistors, or sensors connected to the digital and analog inputs on arduino and how to send digital signal out to control actuators.

The first thing I did was build a circuit with a button and a pull down resistor to read digital (on/off) input from the button, depending on whether it was pushed down to complete the circuit. By connecting it to a digital pin, I could read this information and use it in my program. The next piece was to build two additional circuits with a resistor and LED, and connect each of those to their own digital pin. Then, with some conditional logic, I made one LED light up when the button wasn’t pressed, the other light up when it was pressed.

Next I tried reading analog values from a potentiometer and a force sensor to control the brightness of an LED. By connecting the LED to pin 9 on the arduino, which is a PWM (pulse width modulation) pin, you can simulate analog output which allows for this apparent dimming of the LED. Reading values from a potentiometer and any other variable resistor really aren’t so different.

Realizing that I had already played with analog output with the dimming LED, I wanted to go back to my reflective flower from last week and control it with a variable resistor instead. Since it’s a flower, it made sense that it would react to light, so I used a photoresistor. I had to skip ahead in the labs a little bit, since the motor needs a 9V power supply, and I wasn’t sure how to control the motor with the power supply and the arduino. The answer is: with a transistor! I used a PN2222 transistor (thank you, internet) to connect the analog out from the arduino to the circuit that controlled that power for the motor. My flower responds to light!

Some other issues are that the base isn’t so sturdy, so it works kind of like a spinning top. Also the motor takes a while to slow down, so playing with it you don’t sense an immediate change by lessening the amount of light available. I think it would be cool to hide the photoresistor within the flower somewhere, so that you can control the flower by interacting with it directly.

Typography & word as image

This week was a challenge since I started out knowing nothing about typography or illustrator, but I considered it a cool opportunity to analyze fonts I like and have used in the past without thinking about why, and a good chance to practice very useful software. I’ve had to choose fonts for web projects, so in addition to understanding these choices differently, I was also importing them for use in a very different environment (illustrator, instead of a css file).

I realized very quickly that I don’t like to see my name in sans serif fonts because I’ve always put a cap on my J… I didn’t consider the cap a serif I was led to believe my whole life that this was part of the letter. I’d also never liked the roundness of the J in cursive and generally don’t like when it descends too far past the baseline. I also found some fonts do strange things with the dots on i’s and j’s, which very important in my name, and eliminated fonts where the dots didn’t seem to align with the rest of the letter. I also assessed fonts based on the distance between the J and A in my first name, finding this is often not uniform (although I did take the opportunity to experiment with kerning in illustrator). I chose to display my name in all lowercase or all uppercase since I’ve come to learn I strongly prefer a lowercase j, but also find it useful to assess the all-caps version.

My name in selected serif fonts:

robotoslab -slab serif, geometric, short shoulder on the r (I would not use this if my name had an R in it)

 

 

 

 

bentham

-transitional, round terminal on J

 

 

 

 

nixieone-another slab font, finer stroke, is that a spur on the N?

 

 

 

 

My name in selected sans serif fonts:

newscycle

-grotesque/gothic, uniform weight

 

 

 

 

raleway

-similar but more oval, more stylized terminals

 

 

 

 

poiretone

-fine stroke weight, diagonal stress and short finial on e

 

 

 

 

And all of them together:

The Word as Image exercise was a great chance for me to learn tools available in illustrator both for creating images and manipulating those found elsewhere.

Electronics Labs

For this week’s electronics lab we worked on learning to use a breadboard, building simple circuits, and providing power to our circuit with an arduino or power supply. I worked with LEDs in series and in parallel, resistors, switches including a soft button I built with conductive fabric, and a motor. I practiced measuring voltage, current, and resistance, and to create a spinning reflective flower, I did a little soldering.

I built the soft button at soft lab. The conductive fabric at the soft lab is conductive on both sides, which I checked with a continuity test. On the inside, there’s a thicker layer of fabric that keeps two pieces of conductive fabric from touching. A small hole in the center of the middle layer allows you to press and make both sides touch. I also played with combining a switch with a potentiometer.

Soldering on the bottom of a DC motor – positive and negative only change the direction of the spin

I first tested out the motor with just a key switch and then decided to build a little stand to house it. I soldered the bottom of the motor to wire but didn’t solder together the whole circuit (I am borrowing this button from a friend). I thought having reflective material that moved would create a cool visual effect, so I created this flower controlled with a button. It was actually pretty fun to play with.

Visual Analysis: Movie Poster

I was looking through old movie posters when I saw this one for Harold and Maude that I hadn’t seen before. I found a different version that also included the sunflower motorcycle in English, but from what I could tell this one and its variations were used for a European audience.

haroldemaude The blocks of text make the poster seem to have a square grid, though could see an argument to be made for one that runs along the lines of the motorcycle. The use of negative space emphasizes the three areas of the poster: the title, the image, and the credits. The background is also subtly given some texture with a paintbrush-like effect in a slightly different tint of dark blue.

The bright colors contrast the dark blue space to draw the eye first to the bright yellow title and the orange-pink sunflower wheels. In terms of hierarchy, the next points of attention are the smaller but also vibrant details: the figures on the motorcycle in red and yellow, then things like the plant riding on the back, the noose around Harold’s neck, Maude’s socks, and “Police” written on the bike. It’s also a compelling and funny image that reflects the zany, dark humor of the movie. Last in the hierarchy are the production credits on the bottom of the poster.

heirarchy

The poster uses two sans serif block fonts: Newhouse (I think condensed and bold) for the title and varying sizes of something like Gothic. I searched around but couldn’t nail down the exact font used here.

Edit: After using alternative methods to try to find the title font, I still found the title font to fit the best. The height of the bar on the A, the shape of the O and U AND D all seem right. Many similar fonts had very different M’s… I could see an argument for the leg of the R perhaps not being quite the same. After spending more time looking at font, the kerning between the U and D in “Maude” and the O and L in “Harold” became quite bothersome.

Identifont did help me find a better match for the credit font–no font had the right shape while keeping the legs on the letters short and maintaining the rectangularity of the letters, but the following fonts are at least much closer than Tactic Sans, which I had picked out previously. In analyzing a match, I focused on the D’s, A’s and R’s, but none are are square as those in the poster, which was what made me classify it as similar in the first place. Many similar fonts that I eliminated have even more rounded D’s.

Physical Interaction

What is physical interaction?

 

A physical interaction is an exchange between a person and and object, or machine, where both are intelligently responding to what is being expressed. A good physical interaction is one where the person can tell, or figure out, how to communicate to the object or machine based on design or cues that the object or machine affords resulting in an exchange that makes sense to the person. Then, the interaction invites continued interaction by being responsive, engaging, and maybe even fun. Chris Crawford included “The first rule in business is that you must identify your basis of competitive advantage and then exploit it to the fullest” in the “Computer’s Basis of Competitive Advantage” section of The Art of Interactive Design, which in this context I immediately translated in my mind to: a good interaction lets people do what they do best while letting a computer do what it does best.

 

What is the potential?

 

Bret Victor went even further, giving a sort of urgent, almost moral imperative to push interaction design forward, saying, “…Visions matter. Visions give people a direction and inspire people to act, and a group of inspired people is the most powerful force in the world. If you’re a young person setting off to realize a vision, or an old person setting off to fund one, I really want it to be something worthwhile. Something that genuinely improves how we interact.” This reminded me of Jason Pontin of MIT Technology Review, when reflecting on drones used for warfare he wrote, “Technological advances are not the same as progress.” In a way Victor’s rant was a critique from the opposite end–sometimes achieving some ends are unnecessarily hindered by poor or thoughtless selection of tools. If we want to use technology to progress rather than to stagnate, or worse, regress, then maybe as an extension of this, interactions should facilitate the expression of the best parts of human nature. How can we apply these kinds of principles when we design things?

 

Non-interactive digital technology

 

Examples of digital technology that are not interactive could include almost anything that presents information or media, on the web or otherwise, that is not responsive to the person consuming the information. The expected train arrival in the subway, based on the subway schedule or sensors (depending on the city), communicates information digitally, but does not react in any way when people are annoyed or in a rush. In large part the movies, music, text, and art we view online is not interactive, although some online experiences are specifically designed to be interactive. I am not sure if sites like Netflix or Youtube should be considered interactive–I think they are in the sense that they learn about you and make suggestions based on your previous behavior. Maybe this could be considered a conversation about your likes and interests.
