CMSC434 Introduction to Human-Computer Interaction

Week 01 | Lecture 01 | Sept 02, 2014

Design Activity, Intro to HCI, Intro to Class

Remixed from http://marshmallowchallenge.com/Instructions_files/TED2010_Tom_Wujec_Marshmallow_Challenge_Web_Version.pdf

GOAL: Build the tallest freestanding structure. The winning team is the one with the tallest structure measured from the table top surface to the top of the marshmallow.


RULES: 1. The structure cannot be suspended from a higher structure, like a chair,

ceiling, light

2. The structure cannot be taped to the desk/table.

3. The entire marshmallow must be on top—cutting/eating part of the marshmallow is not allowed

4. Use as much or as little of the kit; however, you cannot use the paper bag as part of your structure

5. You can break up the spaghetti, string, or tape in anyway you want.

6. The challenge lasts 18 minutes. You cannot hold/touch the structure after time runs out. You cannot open the bag until the timer starts.

TEAM MEASUREMENTS:

*Red teams had previous Marshmallow challenge experience


DEBRIEF:

1. How did you approach the task? What was your building process?

2. How did you collaborate and work together?

3. What is the key to a tall structure? Why?

4. What do you think are shared attributes between the most successful teams?

MY THOUGHTS

To me, this task represents a microcosm for the entire semester. This

course is fundamentally about design, which requires creativity,

iteration, and collaboration.

It’s also about working with and within constraints—be it time, money,

or resources. You cannot escape constraints in life or work.

PETER SKILLMAN’S TAKEAWAYS

You learn by doing

Work in parallel

On being first to market

Multiple iterations

All projects have resource

constraints

Peter Skillman, Original Marshmallow Challenge Talk TED, 2006, http://youtu.be/1p5sBzMtB3Q

Learning from the mistakes of others* is

the best way to launch an idea.

* or yourself

Multiple iterations almost always beats

the single-minded commitment to building

your first idea

WORKLOAD

AHEAD

! WARNING “This class is certainly a fun, interesting course to take .. it

will keep you quite busy and you can easily fall behind if

you don't stay on top of your workload.” -CMSC434 Student

“Course was actually intensive in terms of workload, but

we learned more…” -CMSC434 Student

“Overall, the course was a lot of work (as you warned us

in the beginning of the semester), but I learned a lot.

One of the best CS courses I've taken at UMD.” -CMSC434 Student

ACHIEVEMENT UNLOCKED CMSC434 Metacomment

Workload was appropriate.

- CMSC434 Student

Really appreciated the process of learning how to

brainstorm, sketch, plan, and build. Will be useful in

many future endeavors…

- CMSC434 Student

I would have prefer a programming unit in this class

to show us how we can use today's technologies to

connect to what he said in class.

ASSIGNMENTS & ASSESSMENT 70% of your grade is based on your performance on assignments

THE LECTURES

“The professor tries very hard to make the classroom into

a friendly, interactive community where every student is

engaged in learning from the material, the professor, and

each other; and I think he has overwhelmingly

succeeded.”

-CMSC434 Student

ASSIGNMENTS & ASSESSMENT 70% of your grade is based on your performance on assignments

Project Overview Goal: Apply and integrate user-centered concepts learned in this class along with your

other (current and prior) computer science education.

Secondary Goal: Work on real problems! Intense end-to-end design.

Focus: Mobile Applications With Sensor Integration

1. You pitch project ideas

2. We will sketch, prototype, test, and iterate.

3. You have to implement the final prototype in code.

Teams: Divided up based on skills and interest. If you have a significantly good

practical reason for working with someone, let me know.

You must be committed to working with your team throughout the semester.

CMSC434 Design Critique

I think it'd be good to have a say in what group you'll be in, after indicating your initial topic preferences. I got stuck in a group that is pretty apathetic, and it's come through the most with our final project. I've coded 98% of it, and I can't do anything about it, because we set a mutually agreed schedule for adding code. There's only so many times I can keep asking for contribution when the group members don't care.

DESIGN CRITIQUES / PEER REVIEW

Really liked how we reviewed the class' works and that you

guys actually handed us these peer reviews back. Definitely a

good way to get good feedback.”

Hall of Fame Hall of Shame

As you watch the following video, think about why designing such

an interactive system is hard and why the user struggles

Touchscreen Soda Fountain Submitted by: Jon Froehlich

Why is this a hard design problem?

Why did the user struggle?

Facebook Inline Translation Submitted by: Jon Froehlich

Hall of Fame Hall of Shame

Submit your video recording (screen capture or cell phone) along with a

paragraph (or two) description of why its Hall of Fame or Hall of Shame. Your

description must include principles learned from class.
