To prepare the requirements for this course, enrolled students may conduct peer-to-peer participant studies using their peers as participants. Methods may include interviews, observations, surveys, co-design activity, heuristic evaluations, and cognitive walkthroughs. As part of this design research activity, students conducting these studies may take written notes, photographs, and/or video as a means of documentation. This documentation may appear in papers, videos, and conferences for academic audiences. Student will not be identified by name, and no aspect of these studies should cause discomfort or risk to participants. Should any student in the class choose not to participate in any aspect of the study, or have questions about her/his participation, please make this known to the instructor. Additionally, for any work of the course submitted for publication, student authors will be identified as first authors of the submission, and the instructor will follow in the list of authors of such work in recognition of their efforts in cultivating this work. If these term are not acceptable to you, please indicate so to the instructor. Non-participation will not impact your grade for this course in any way.

Human-Centered Design Methods are used to design things and the interactions between these things and the people who use or inhabit them. As such, Human-Centered Design is not only about form-making but also an attentiveness to the needs and opportunities of people and the planet, striving to improve lives, enhance existing places, and support interactions of human and other living beings with their surroundings. This course focuses on designing interactive devices, given that interactive devices (including interactive environments) are growing in number, kind, and complexity and have great promise for supporting and augmenting human lives. Designers use Human-Centered Design Methods especially in industrial and product design, healthcare design, retail design, interaction design (IxD), user experience design (UX), human-computer interaction (HCI), and mechanical engineering.

You will be provided the following in class:

- 1 Grove Beginner Kit for Arduino ($23.88 from Mouser).
- 1 Grove Servo ($6.90 from Mouser).
- 1 Grove Ultrasonic Sensor ($4.30 from Mouser).
- 1 Grove Gesture Sensor ($10.99 from Mouser).
- 1 Grove RGB LED Stick (15-WS2813 Mini; $5.40 from Mouser).
- 1 Grove Switch ($3.20 from Mouser).
- 1 USB Battery Pack - 2200 mAh Capacity - 5V 1A Output ($14.95 from Adafruit).
- Panels (pre-cut) to make an enclosure for your assignment-1. If you need a different size enclosure, you can work with D2FS on laser-cutting panels to-size from digital files you generate using CaseMaker.

You will need in class:

  • Your laptop. You need your laptop in class, every class session. If your laptop is not equipped with a port to plug in a USB-A cable (that comes with the Grove Kit), then you need a USB-C hub (here's one) that plugs into your laptop's port and provides a USB-A port. Newer Mac laptops need this USB-C hub, as Macs no longer have USB-A ports on them.

You may also need:

  • 1 sketchbook like this one or a comparable one found in our bookstore.
  • Fabrication materials for early, rapid prototyping. These include: cardboard from shipping boxes, plastic from fruit and vegetable containers, and craft materials needed to construct your prototypes. Many of these materials you have already, at no-cost; other materials are available from the Cornell Bookstore, Michael's at the Ithaca Mall, and online at Utrecht, Blick, and Amazon.

In this course, we are iteratively designing and evaluating a small, interactive device as defined by our DESIGN CHALLENGE (see the description below). We are designing this device as a platform to practice the numerous ideation strategies and evaluation methods of this course.

In more practical terms, what are we designing?

  • A small, physical object (not a mobile app or an otherwise screen-based app)

  • An object that is interactive - that may light up, change color, make sounds, and/or move or change shape - when someone does something (near or far from it) or something happens (near or far from it).
  • An object that provides an experience that impacts behavior.

  • An object that is not only impactful but fun - an experience worth talking about.

  • An object that is more like a jack-in-the-box and less like a measuring device.

If you still can't answer the question, What are we designing?, see these slides that answer the question with reference to a typical DEA 2730 Design Challenge.

The New York magazine article, "The Uninhabitable Earth," is the most-read article in the magazine's history. The article presents the scientifically projected fate of our planet due to climate change, organized by impact: on water, air, weather, the economy, war, and on other facets of life on our planet. 

Recent reporting on NPR (National Public Radio) provides evidence that 70% of Americans see climate change as a future crisis, not the urgent crisis recognized by the scientific community. Climate change, for the majority of Americans, is not something they are thinking and talking about. But "some experts believe the way we talk about the changing climate can change attitudes."

Your challenge: to iteratively design, prototype, and test an interactive device that helps make university students talk about climate change. By displaying such a device, you make visible to students you encounter (as you move about the campus) manifestations of climate change that gets them talking. Talking about climate change, as the NPR report shows, can make university students more mindful of climate change as an urgent problem. Your device does this by evoking, by LED lighting, electronic sounds, and/or movement, a manifestation of climate change. This means your box will look like like its flooded, on fire, suffering a drought, sweltering in the heat, melting, smoky, wind swept....

The research questions you will answer by way of Human Centered Design Methods is: Can an interactive device that captures a manifestation of climate change make people talk more and, so, become more mindful of climate change? 

Your device must be a physical thing made interactive using the Grove kit with at least one input and one output. It hangs by the provided hook from a backpack.

Your design group has a new client who wants you to develop this interactive device where all the electronics (limited to those provided in class), including the rechargeable battery, fit inside a rectangular, translucent box, 8" x 5" x 1.5" (provided in class).
Your client restricts your design to that box and those electronics.

To explore the viability of this new product, the client asks you to pitch the design twice: once (in a week’s time) to present your quick effort to generate a fully-working device, and a second time (15 weeks later) to assess your longer effort to generate a refined prototype informed by user input.

Please review carefully the POLICIES found below. These policies are not negotiable except under grave circumstances.

Assignments are individual efforts; however, in class, you will be viewing the work of peers and sharing your own work to inform one another. In this way, DEA 2730 is a “conversation” across students, professor, and TA during which you will have ample opportunity to learn and receive feedback on your work.

The list that follows names and describes the graded components for this course. Each component is worth so many points, as shown in red type
. The sum of all of these components equals the final grade of 100 points. The numerical scale for grading is as follows: A+ (98–100), A (93–97), A- (90–92), B+ (88–89), B (83–87), B- (80–82), C+ (78–79), C (73–77), C- (70–72), D+ (68–69), D (65–67), D- (below 65).

5 points | IRB CERTIFICATE of completion of training on studies with humans.
From this Cornell IRB link, on the linked page, select this required IRB training by:
1. clicking on the blue box, "TAKE CITI TRAINING (CORNELL LOG-IN)
2. entering your credentials (email address, ....)
3. selecting, as your role, from the pull-down menu "Student Researcher - Undergraduate"
4. selecting, as the course you plan to take, from the pull-down menu, "Basic Human Subjects – Social & Behavioral Focus."
After finishing the course, email the certificate of completion you receive to the TA before the due date shown in the SCHEDULE above. Failure to complete this task or late submission results in a zero grade for this component of the course. No excuse.

This demo is done as a 2-minute pitch in class following two days of focusing on rapid prototyping (see course schedule above). Show us that you can make work, using Grove, any example code that I provided on this course webpage under the heading, "Arduino Code You Can Copy & Paste." This assignment is Pass or Fail: you receive 5 pts if you pitch a working demo; you receive zero points if you fail to do so. If you miss the class for the pitch, then you make and submit a video to our shared folder. What to upload: a Word .doc with a link to a video (Vimeo or YouTube) of the working system, uploaded to our shared folder by 11:59pm on the due date shown on this webpage. Name your Word .doc [My Name]-Grove-Demo.doc.

10 points | IDEATION [Rubric] | Examples 1, 2 from DEA 2730.
Upload to our shared folder for grading, by the due date shown in the SCHEDULE above, PowerPoint slides (or pdf pages, if you use an application other than PowerPoint to make slides). Name this file [My Name]-Ideation.pptx or .pdf. These slides contain your one best example of each ideation strategy, 01-08 (see the upper-left of this webpage for the list of these). For the rapid prototype, simply past into the slide two photos: one photo of your prototype in one state (e.g., glowing red), and one photo of your prototype in another state (e.g., glowing blue). Your last slide should be your animated GIF as simply an embedded gif. in your slide and a link (URL) to a video posted on Vimeo or YouTube. In IDEATION, we are looking for, especially, your insights, following each ideation strategy, of what you learned from it to advance your design, and evidence of your design changing.

10 points | CONCEPT [Rubric] | Examples 1*, 2* (*requirements may be different)
Upload to our shared folder your Concept (for grading, worth 10pts; Grading Rubric) as PowerPoint slides or pdf pages (if you use an application other than PowerPoint to make slides). Upload your slide file as [your name], organized as follows:

Slide-1: a title slide with a name and logo for your prototype and a money shot.
Slide-2: your 09. Scenario in written text.
Slide-3: your 10. Role Play captured by video: provide URL link to Vimeo or YouTube.
Slide-4+: your 11. Survey (User Experience - UX) showing questions and results.
Last Slide: print ad for your concept, for WIRED magazine (size 8″ by 10- 7/8″). 

30 points | EXAM on key term, names, numbers, and case studies from this course up to the moment of the exam. The content for this exam is found partly in the assigned readings; come to class to discover the rest! (I do not share my lecture slides.) For the exam, you will be provided a word bank (that includes, e.g., focus group) from which you select and enter the word that best completes the sentences (e.g., A _________is a kind of interview that that brings together a number of people in a room to provide feedback regarding a product). To answer this example, you would select from the word bank and enter focus group. If you need to make-up the exam due to an excused absence, this exam will be a short essay form where you will be offered key terms, names and numbers considered in class and you will be asked to define them, compare them, and/or provide a practical examples of them.

10 points | FINAL WORKING DEMO, presented during our final class sessions.
You will graded on the demonstration, in class, of your physical, interactive prototype with embedded, functioning Grove electronics. Show us something that works! Grading is simple: you earn...

  • 10 points if you demo for us, in class, a substantially finished, physical prototype with a fully-functioning, interactive Grove system (i.e., at least one input and one output).
  • 5 points if you demo for us, in class, a partly-finished, physical prototype or a partly-functioning Grove system.
  • 0 points of you fail to present a physical prototype in class.

The demonstration of your working prototype will be the key component of your 3-minute pitch, delivered in class, aimed at "selling us" on your design, as if we were your clients or your investors. TIP: Speak more words than you show in slides. Slides should have very few words and figures.

To support your pitch, you will prepare and upload to our shared folder a pitch deck of no more than 5 slides that will help you present: [a] the problem you’re addressing; [b] how you're addressing it; [c] what the experience is; [d] why it's important; [e] why we want it - in 3 minutes! In preparing these slides, this webpage might be helpful. Upload your slide file as [your name]_presentation.pdf.

In the unlikely event you have an excused absence for the WORKING DEMO days, upload to our shared folder a Word doc. with a URL to a YouTube or Vimeo movie showing you giving this same presentation. Your Word .doc must be uploaded by the due date for final deliverables for this course(i.e., our Poster and Video) as set by the Cornell registrar (see date above). Given that you will have extra time to complete this assignment, the grading of your demo will be more rigorous to be fair to your peers that presented their demos in class more than two weeks earlier.

15 points | POSTER | Ex.s 1, 2, 3, 4, 5
15 points | VIDEO |

(a) [My Name]-Poster.pdf <15MB
(b) [My Name]-Video.doc - simply the URL for your Vimeo or YouTube video
(c) [My Name]-Video.mp4 <30MB using Handbrake (free app to reduce file size.
(d) [My Name]-What_did_I_learn.pdf - a pdf containing a scan of all the forms you completed over the entire semster

The POSTER [Rubric, guide], 30" wide x 40" high, communicating in a compelling way the iterative, human-centered design process for your development of an interactive artifact. You are not reporting on all ideation strategies and design research methods; only those that make the most cohesive, compelling reporting of your design process and final outcomes. Your poster will be named, [My Name]-Poster.pdf < 15MB.

The VIDEO [Rubric, guide] communicating s cohesive story of the designed artifact you produced, offering the societal problem, introducing your design, and answering why, for whom, and how your design was developed, including briefly key findings of your user studies. For the video, (a) upload a Word doc that simply has a URL link to your video posted to Vimeo or YouTube; and (b) upload to our shared folder an mp4 file reduced to < 30MB using, e.g., Handbrake, a free app that reduces video file sizes and changes the codec from, e.g., .mov to .mp4 (see my guide about this). Your two video uploads will be named My Name]-Video.doc that contains simply the URL for your Vimeo or YouTube video, and [My Name]-Video.mp4.

Notes on video making:
[1] If you do not have access to video editing software (e.g., iMovie), try Open Shop, a free video editing app for windows

[2] My guide follows requirements for a Video Showcase submission to the ACM conference, CHI (a benchmark for design research). If you believe you have a great video, consider submitting yours to CHI and, if accepted, attend the conference.

No exceptions but for the gravest circumstances, documented.

P1. Come to class. You might discover something.
Unlike a large lecture course, this course is not just about lectures but also:

  • case study videos
  • discussions of previous student examples
  • critiques by the professor, TA, and student-peers of developing student work
  • answers to student questions
  • guest visits

When you miss a class, you miss these rich classroom experiences and fail to share your work and your voice to benefit yourself and your peers. Come to class, participate: you might be surprised to discover something important here. In design, we work together.

(If you need help with academic advising or mental health, please make use of the resources available on campus as described in this guide to Cornell Mental Health Resources.)

P2. Follow instructions for the assignments.
Follow instructions carefully for all assignments. Failure to abide by the instructions for any assignment will lower your grade for that assignment.

P3. Get the file format right.
Your submitted work must be submitted in the format stated on the course page for each assignment. Digital files and URLs (e.g., links to videos) must be accessible, without us requesting access-privileges. Google Docs are never acceptable. 3 points (of the 100 points total for the semester grade) will be deducted from each assignment that does not comply. Too many students lose points for failing to follow this simple instruction; if you fail to follow this simple instruction, you will be the next!

P4. Extensions will be granted, but only for grave circumstances.
If you need an extension for any assignment, email both the instructor and the TA (if there is one) ahead of the due date and make a case for your extension, attaching evidence when available. Extensions may be granted for illness, injury, or family emergency requiring your travel. No extension will be granted because work is due for other classes, or because you are traveling for a non-emergency. Don’t even ask.

P5. If you want a high grade, match or better the quality of the best previous work.
The course page for this course offers student examples of “best work” from previous semesters. Your work will be evaluated relative to these “best work” examples when available. If you disagree with a grade for any work in this course, make a case for reconsideration in an email both to the instructor and the TA (if there is one). Why does your work merit a better grade? Do not ask for reconsideration during, before, or after a class session; your request must be submitted in writing by email. And if you ask for reconsideration of a grade for an assignment, you grant the instructor and the TA permission to reconsider your grade for any part of that assignment, which may result in a better grade, no change of grade, or lowering of the grade.  

P6. No slides are shared.
No slides are shared for this course, apart from those few slides linked from our course page. The exam is based mostly on the content presented in-class. If you miss a class, ask a classmate for notes. The instructor and TA don’t have notes for you.

P7. Make-up exams may be in any format the instructor chooses.
If you are absent from any exam for this course, the make-up exam may be in any format the instructor chooses (e.g., long or short essay form).
