Prototyping a Networked Family

4 Comments Design, Education, Examples, Physical Computing, project, Social Media, Technology

Being a first time dad has been the most amazing experience of my life. Watching my daughter grow, and witnessing her constant exploration of the world around her has been extraordinary. Unfortunately when Mondays roll around, it is time for me and many other parents to drop off our kids at the babysitter.  The amount of time we get to interact with each other is very minimal, and pretty sad.

In a world where we all feel so “connected”, the people that matter most have no method of remotely interacting with us.  My 1 1/2 year has no twitter, or Facebook account to update.  She doesn’t check into fourSquare every time we go to grandma’s house. Even with mobile phones and Skype video conferencing, there is no direct method of me interacting with her without the assistance and supervision of an adult. So basically, we could only interact with each other when another adult has both the time and is willing to put in the effort to set up an environment for us to communicate.

This got me thinking “how can my daughter and I interact during my work hours?”  The first thing I did was identify the main characteristics of my daughter, back when I first started working on this project:

  • My daughter was one year old.
  • Her vocal communication ability was in the preliminary stages of development
  • Her motor skills where still not fully developed, so complex tasks like using a keyboard or mouse where not possible.
  • She needs adult assistance to use our everyday communication tools that available to us (moble and land-line phones, computers, etc).

At this young age, children are extremely dependent on their parents and other adults for just about everything.  However, there are also several activities that come as naturally as breathing and eating to a child. Two of those activities that i observed where exploration and play, many times triggered by a common catalyst of curiosity.

Children gradually explore their environment and toys and interacted with them, mastering the new skills that they learn along the way. Quickly they are able to identify all sorts of toy input locations which triggered various types of output, such as audio and visual feedback.

Lessons Learned: Designing Toys for Children 7months-2yrs

1 Comment Design, Education, Physical Computing

I have spent the past few month deconstructing the cognitive, emotional and social attributes of children under the age of two. I have been particularly interested in understanding why children are more responsive to some toys, then they are for others. What makes a successful toy, and why? What strategies could be used in the development of a toy to foster learning opportunities, along with several other question regarding this ripe age and this medium.

This age is quite interesting since you are not only designing for the child, but also for the parent, who acts as the gatekeeper. This adds an additional level of complexity, and understanding that needs to be understood. So the first question I asked myself was, “What does a parent look for in a toy?”

According to the book, “The Blockbuster Toys”, parents look for toys that;

  • Child’s Safety
  • Child’s Continued Enjoyment (play value)
  • Child’s Creativity
  • Child’s Mental & Physical Development
  • Child’s Success
  • Child’s Health
  • Child’s Love

I added some additional bullets that I’ve noticed parents, including myself look into when purchasing a toy: Read more

Multi-Master Arduino Setup using i2c

1 Comment Examples, Physical Computing, programing

I working on a project, I was faced with a challenge of creating a serial bus via multiple Arduino which could communicate with each other. My first intuition, after a little push in the right direction by Tom Igoe, was to create a Master/Slave setup where a Master micro-controller polls all the slave micro-controllers, and dispatches an action. Although this answered one of my question, polling didn’t allow for complete 2-way communication. It tuned out that the answer was mainly an oversight of my interpretation of the Wire documentation.

From Arduino Site:

Wire.begin()
Wire.begin(address)
====
Description
Initiate the Wire library and join the I2C bus as a master or slave.
====
Parameters
address: the 7-bit slave address (optional); if not specified, join the bus as a master.
====
Returns
none

I interpreted this explanation as Wire.begin(SomeAddress) would default as a slave, and not be allowed to be a Master. Being as curious, and stubborn as I typically am, i decided to forget what I thought I was being told, and instead try to break the library, so I could then see where it broke, and attempt to adjust it in a way that better suited my need. Surprise, surprise, it worked, and not need to change anything at all! The address parameter is optional and defaults as a master role if no address is set. However if you do plan on sending messages to the master, you could switch speaker and listener roles via a slaves Wire.onReceive(handler) rather then polling using onRequest(handler). Read more

Sensing Child’s Play: Examining 7 toys from the toybox

No Comments Design, Education, Physical Computing, Technology

I have always had a fascination with trying to understand how the things around me work. It just so happens that after having a child, most of the thing around me are toys. Large toys, small toy, blinking lights, sounds, singing, haptics, interactivity, it is all pretty darn amazing when you sit back and really look at how much technology my little one year old daughter navigates and interacts with during play. Many time when we think of children and technology we automatically think of desktop computers and video game consoles. Although all of these are examples of technology the only interaction my daughter has with them is me telling her, “don’t touch”, and handing her a toy to distract her attention.

I decided to take a trip to my daughter’s toy collection to examine some of the sensing capabilities that her electronic toys offer. I will specifically focus on the toys input capabilities:

(At the end of the post there is a video of me trying to figure out how the LeapFrog Tag Jr works. Let me know your thoughts.)

Fisher-Price Elmo Live Encore

This is by far one my daughters favorite toys. The toy is modeled after Elmo, a Sesame Street character, which most children a quickly drawn to by his bright red color, large eyes, and youthfully fun voice.

Inputs

  • Push Buttons: Typically buttons on toys are visually obvious, however Fisher Price decided to create an exploratory interaction by spreading out four button throughout the plush doll. Three of the buttons are hidden under the fabric, on the toe, chest, and back, and the final button switch is closed by squeezing his nose.
  • Tilt Sensor: One of the nice additions that the creators added to the toy was integration of a Tilt Sensor. When Elmo falls on his side, he politely ask for help to stand backup, which is sometime accompanied with a joke.

Initial Test of my Expandable/Interchangeable Circuit

1 Comment Examples, Physical Computing, programing

So what do i mean by expandable? Basically the idea is that I would like the cheapest possible way to be able to create a circuit that I could chain sub circuits too (those are the 2 sub circuits in the video). After lots of trial and error, I was able to put on my crafty hat to make these darn electrons work the way I wanted them too.

In the accompanying video, I give a quick run through of how the circuit works. Essentially, the main goal that I was able to achieve was that I would be able to clone one the inner circuits and add it right in the middle. All I would need to do is connect them to the 2 digital pins, 2 analog pins, one ground, and one 5V series, and it should work without any additional rewiring (although the idea is to make the sub circuits slightly different in their interaction, yet the same in their communication), asides from programing the EEPROM (I used the 24LC256 from SparkFun for $1.95) to contain a unique identifier. The secret to success…diodes..lots of them.

I based my code on a great snippet of code to help me get the I2C communication working on my EEPROMs. I also checked out a helpful tutorial which also helped me out substantially.

One quick tip: Keep in mind that Arduino has an EEPROM mounted on the chip. I intially made the silly mistake of using the EEPROM code that is found on the Arduino tutorial page. This code was reading and writing data on my Arduino’s board mounted EEPROM, which i quickly realized once I realized that the unique data I was writing on each external EEPROM chip did not seem to be working properly.

So why go through all this extra effort? Read more

Update Twitter Status w/ Arduino & Processing

8 Comments Examples, Physical Computing, programing

The next phase of my project was to send the serial communication from my Arduino, over to Processing, which then would formulate a status update based on the button you pressed and send it over to Twitter. I’ve worked with several Twitter API’s in the past, so I decided to go with Twitter4J, the “J” in this case stands for Java, which works perfectly with Processing.

Bellow is an updated version of my previous Arduino coding. I plan on switching the status updating to the Processing side, instead of the Arduino side. If this where to be a real product, it would be easier to download a software update, then to have to reprogram the toy itself. I will add that to my todo list, once i get all the major Read more

Arduino: Print a Single Serial Message per Button Press

No Comments Examples, Physical Computing, programing

So I’ve been working on a new project and have run into a bit of an issue. I plan to send a serial message over to Processing, however it very important that I don’t send multiple values stating the same button press. Since Arduino is in a constant loop state, when i press a button using something like:

Examining an Everyday Physical Object

2 Comments Design, Physical Computing

At any given moment we are all surrounded by interactivity. From using the toaster, to setting up your DVR to record your favorite show, interaction with physical objects is part of our everyday life. Coming from a web centric outlook, I typically associate words such as interactivity to the multimedia and computer software, however interaction far exceeds the spatial confines of our monitors.

Breaking free of the monitor, and starting my voyage into the physical realms of physical computing, I decided to step-back and analyze some of the physical objects that I regularly interact with. It wasn’t long before I noticed the perfect subject.

The Metro Card Vending Machine is a common place for many New Yorkers. As a matter of fact, I thought it had a rather intuitive design, until this morning. They have incorporated a sexy touch screen design, with large buttons so clumsy fingers don’t press the wrong thing. In my opinion the interface is quite intuitive and rather pleasant experience, or as pleasant as refilling your Metro Card could possibly be. Read more
