BlueWay Lives!

No longer is BlueWay a mere figment of the imagination. There’s a ton left to do but currently it:

- Senses Bluetooth IDs in a variety of locations
- Matches those IDs to a database of people
- Displays the owner’s photo in a collage
- Fades that photo away when the ID hasn’t been sensed in a while

High on the to-do list is associating each photo with a sensor position, creating dynamic behaviors for each photo object so they cluster but don’t overlap, and a bunch of code cleanup to make it easier to read, more robust and simpler to expand.

Lobby Display

Over the past semester I’ve been coordinating the public ITP lobby display. Student and faculty works are presented to the New York City public on a large plasma display facing the corner of Waverly Street and Broadway. Works include:

Our student coordinating group varies over the semester, but usually includes Kate Hartman, Andrew Schneider, Leif Krinkle, Kati London and Gilad Lotan. Our faculty adviser is Dan Shiffman. We’re looking forward to putting more experimental projects in front of the public over the summer.

BlueWay Participatory Design

Here’s the presentation we gave (31MB) on our participatory design work for the BlueWay sign system. The project context has changed to the ITP Spring Show. We interviewed potential users about what they might expect from such a system, had them perform a card-sorting task to organize information about the show, and asked them to draw how they felt that information would be displayed. It was a very revealing exercise which guided us toward focusing on presence. Social information ranks very highly with humans, so our user’s interest in seeing who is around them makes a lot of sense.

XBee Practical Example

Over the last couple days I’ve created an XBee Practical Example for using the XBee ZigBee radios in paired communication between two PIC microcontrollers. It is intended for use by those who have a basic familiarity with physical computing, and a healthy appetite for shiny, shiny new technology.

BlueWay Sign Presentation

Arly Ross, David Yates, Myra Einstein and I gave a presentation yesterday to our Interaction Design class on the Bluetooth-enabled sign system we are proposing for New York’s Penn Station. I have also begun building the electronics as a proof of concept for my Network Objects class’ final project.

10 Revised Ideas

Our User-centered Design class ideas for toy designs have been revised. Here’s a website with more information about the project. The links along the right side show our research, ideas and some user scenarios, including terrific artwork by Carlos Borges, my project partner.

Wireless Bluetooth Sensor

This is the progress to date on creating a wireless Bluetooth ID sensor modules. The finished system will be used to deliver useful information based upon who is near a particular sensor. Potential applications include a system to determine who is currently in the office, and a signage system that provides personalized wayfinding information to travelers as they pass by.

The Bluetooth sensor is wired to a microcontroller that requests the discoverable Bluetooth IDs within 10 meters of the sensor. This information is then passed out of the sensor module via an XBee brand ZigBee radio to a base station. The current base station sends the IDs via serial to a computer, but the next version will use a Lantronix XPort to send them over the Internet to a server program.

10 Ideas for Adult / Child Toys

1. Mommy Made It
A series of kits for adults to make children’s toys. For example, one moderate skill level kit would allow an adult to assemble a self-propelled wooden car using precut parts that needed to be sanded and painted before assembly. Children could help with the construction, but many steps would need to be done by the adult.
- interactive
- emotional attachment
- group activity
- developmental

2. Riding Vacuum
A self-propelled or pedal propelled riding toy with a built-in Dustbuster style vacuum. Children would clean the floor as they traveled over it, entertaining themselves while helping adults with a chore.
- helping activity
- group activity
- physical
- cute

3. Draw Tracks
A train that follows a specially drawn line on a large piece of butcher paper. The line includes switch points and various control symbols that are complex enough so that an adult needs to help. The adult would build skill with creating the tracks, while the children play.
- interactive
- emotional attachment
- group activity
- trains

4. Ball Puzzle
A pixel-type puzzle created out of differently colored superballs, perhaps 100 of them. The puzzle could be easy–making a picture out of solid color ball-pixels, and also have a more difficult mode where the balls (or one side of each ball) would need to be placed in a proper orientation.
- interactive
- group activity
- spheres

5. Grow-a-Meal
Box contains everything you need to grow a meal from seeds. After assembling the planter (see Mommy Made It above) seeds would be planted to grow the ingredients for a particular dish or baked good. After harvesting, the child and adult would prepare “their” meal together.
- interactive
- emotional attachment
- group activity
- developmental

6. Musical Play-a-Long
This musical instrument would be played by both parent and child. For example, the child could blow into it while the adult worked the valves.
- noise
- group activity
- developmental

7. Sack of Skipping Rocks
As an adult, I’ve become very good at skipping rocks across a pond and notice that children are fascinated by this. Unfortunately, there’s almost never enough good rocks that are easy to skip, so it’s very hard to teach this skill. The sack of skipping rocks would contain enough flat smooth stones so that an adult could learn this skill and teach it to their child. Perhaps the “rocks” could be baked in advance from a powder, like Shrinky-Dinks.
- physical
- group activity
- emotional attachment

8. ReadTV
Books that play on the living room television. One page comes up at a time with subtitled text. The adult reads the text while the child sits with them. Page turns are activated by remote control. The “book” device could be an inexpensive electronic module that plugs into the analog video input on the television monitor. Books could also be read remotely, over the phone by traveling parents or grandparents, with the page turns activated by touch-tone.
- emotional attachment
- developmental
- remote use or physical proximity

9. Make-a-Book
Perhaps part of the Mommy Made It line of parent-child activities, this product would provide all the physical materials for creating a children’s book. It would also feature expert guidance on creating a compelling story line in a step-by-step story structure process. Assistance with drawings would complete the package, using clip art and illustration tips. Children could assist with the process, which would require significant adult interaction.
- creative
- emotional attachment
- group activity
- developmental

10. My Little Treadmill
Children would exercise alongside their parents in a scaled-down version of adult exercise machines. A race component could be activated to scale the adult and child’s speed for a fair competition.
- physical activity
- group activity
- mental engagement
- cute

Insights & Opportunties

This is our presentation on Insights and Opportunities for User-centered Design class.

Tap ‘n Test

We’ve put together a Processing program to simulate the user interaction for the Tap ‘n Tell game. The code currently needs to run on a local computer, inside Processing.
