As we've all experienced during the pandemic, extended periods of isolation - at home or elsewhere - present challenges and (maybe) a few opportunities.

Your HCD challenge this semester is to iteratively design, prototype, and test an interactive device (see example interactive devices) that makes better isolation in some way(s), such as in:

  • better connections to friends
  • better routines
  • better mental health
  • better diversions
  • better focus
  • better breaks from sitting
  • better sleep

The following New York Times articles may help your thinking:

Your device must be a physical thing made interactive using the Grove kit.

The research question you will answer by way of HCD research is:

Can an interactive device improve extended periods of isolation?

Required: attendance, timely arrival to class, participation, and the uploading of all documents
to the course Box or Google Drive folder strictly adhering to all formatting requirement and specifications detailed here on the course webpage and linked guides.

Attendance and Participation is worth 10 points of 100 points total for the course. Attendance at the start of class will be taken. For each absence or late arrival, email the professor and TA with an explanation, attaching supporting documentation (e.g., doctor’s note); the email and attached evidence will be considered as a valid excuse (hardship, medical appointment) without penalty, or not. It is your education, so take responsibility for attending all class sessions, arriving on time. Absences or late arrivals without an approved excuse will lower your Attendance and Participation grade (up to 10 points) as follows:
2 points for each absence
1 point for late arrivals/10+ min.
You are permitted one unexcused absence without penalty.

Late submissions will NOT be accepted except with a doctor’s note or other proof of personal crisis or hardship. Failure to submit the printed documents and digital files on-time will reduce your final assignment grade 10 points.

If you need help with advising or mental health, please make use of the resources available on campus, found here: Cornell Mental Health Resources Guide.

Grading for this course is carefully determined by the professor and TA with thoughtful consideration. If you believe the grade for any component of this class including the final grade is incorrect, you may submit a written argument along with the component-in-question for reassessment. The written argument must reference a specific issue with the graded component of the course and must be thoroughly substantiated. The professor and TA will together consider the request, potentially with the assistance of other faculty with expertise in the area. The reassessment will result in any of the following outcomes: no change of grade, a change of grade for the better, or a change of grade for the worse.You understand that the grade for work submitted for reassessment may result in a grade lower than originally assigned.

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 think-alouds. 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.

This course explores the use of design methods to generate ideas and evaluate designed objects, environments, and interfaces. Lectures cultivate an understanding of the various methods, while hands-on activities provide opportunities to apply these methods to the design of artifacts and their interactions with people and things.

"Human-Centered Design Methods" (HCDMs) are used in the iterative, design-and- evaluation process of design practice and design research. HCDMs are not only used to design things but also to design the interactions between things and the people who use them and live in them. An "Interaction Designer" is the title for a designer who designs things and their relationships with other things, including people. As follows, Interaction design is not only about form-making and composition; it is moreover about creative and meticulous design, it's about technology, and it's about 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 physical and digital surroundings. This course, in particular, focuses on designing interactive artifacts, as interactive devices and environments are growing in number, kind, and complexity.

Three learning outcomes are expected of this course:

Outcome 1. To develop an understanding of how and which design methodologies can be applied in the iterative process of designing artifacts.

Outcome 2. To demonstrate the ability to develop and evaluate design prototypes responsive to the challenges and opportunities of supporting and augmenting human users.

Outcome 3. To communicate a design process in a rigorous written poster and video (that satisfy the requirements of a benchmark, design-research conference).

NOTE: I do not share my lecture slides. Come to class, read the short assigned readings, and become familiar with the basic terms of human centered design.

In this course, we are iteratively designing and evaluating a small, interactive artifact as defined by our DESIGN CHALLENGE (see the description of this challenge in the narrow column on the left of this webpage). We are designing this artifact as a means to practice the numerous ideation strategies and evaluation methods that define this course. While some class time will be devoted to workshop activity during which students design and evaluate their interactive artifacts, in-class workshop activity is brief and you will need to work outside class.

In more practical terms, what are we designing?

  • A small physical object (not a mobile app or an otherwise screen-based app). If you must create an app that intereacts wtih or controls your physical object, you can WOz the app or develop the app rather easily using MIT App inventor).
  • 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). The practice of designing interactive artifacts is often referred to as interaction design or physical computing.
  • An object that provides an experience that impacts behavior, characterized as persuasive technology fostering sustainable behavior and also earth stewardship.
  • An object that is not only impactful but also playful, fun, whimsical; an object that provides an experience worth talking about.
  • An object that is more like a jack-in-the-box and less like a number counter, a measuring scale, a thermometer, and other measuring devices.
  • Examples. The lovebox [link] is a good example of the kind of product we are striving for: small in scale, whimsical/poetic, beautifully crafted, interactive, meaningful/purposeful, and kinetic. Spend time reviewing, also: musicBottles, example interactive artifacts from the ACM "Demo Hour" of Interactions: projects from TU Delft's Interactive Environments program. You might also find inspiration and ideas from Make.

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

Material costs are expected to be approximately $100 per student. This includes the purchase, by each student, of:

  • 1 sketchbook like this one or a comparable one found in our bookstore.

  • 1 Grove Beginner Kit for Arduino (intro video) and additional Grove Components. Mouser eletronics offers Grove kits and components with competitive pricing and quick shipping. Grove products are also available from Amazon (often at a much higher price), from DigiKey, from other vendors listed on this page, below, and directly from Seeed Studio, the manufacturer, which now ships from its US warehouse. For assignment-1, you will need:
    - 1
    Grove Beginner Kit for Arduino ($23.88 from Mouser).
    - 1 Grove Servo ($5.90).
    - 1 Grove Ultrasonic Sensor
    1 Grove Gesture sensor ($10.99).
    Brighter LEDs of various colors will be provided you in class.

  • Aluminum foil - 1 roll, any brand, as used in your kitchen (example).

  • 1 9V battery -or- 1 portable (phone) charger with USB port (here's one).

  • 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.

  • Fabrication materials for early, rapid prototyping. These include: cardboard from boxes, plastic from fruit and vegetable containers, and craft materials needed to construct your prototypes. Many of these materials you have already, like cardboard from boxes, plastic from fruit packaging; paper and glue. Other sources for materials are the Cornell Bookstore, Michael's at the Ithaca Mall, and online at Utrecht, Blick, and Amazon.

  • Fabrication materials needed for high-fidelity prototyping
    • Some fabrication materials are available to you at no cost from our D2FS.
    • Some wood and plastic sheet materials can be purchased from the D2FS.
    Coroplast corrugated plastic is easy to work with and low-cost. I like the colorless, translucent finish - small quantities can be found on eBay via Duco Plastics (clear and colors -- maybe your best vendor), on Amazon from various vendors, and from Home Depot (white in large, single sheets; clear by case of 10).
    Honeycomb cardboard is inexpensive, and rigid enough so to build furniture.
    • Acrylic sheets and other plastics are available online from TAP Plastics (cut to your size with reasonable precision) and from ePlastics (cut to size and less expensive than TAP, but with less control over dimensions of multiple cuts).
    Cut2Size Metals will do what they promise in their name.
    Aluminum Composite Material (ACM): on the red entry of HEB and my LIT ROOM; available locally (Syracuse) from Polymershapes / Kevin Passerell.

The assignments are all individual efforts, not team or group work; however, you will be working in parallel with your peers all semester, to exchange ideas and inform one another's human-centered design and evaluation activity. Throughout this course—an intimate and intensive “conversation” across students, professor, and TA—students will have ample opportunity to receive feedback on their work. Students will receive a grade in response to work, weighted as follows:

10 points Attendance and Participation. Attendance will be taken by the TA in the first 10 minutes of class. Absences or late arrivals, without an approved excuse that was submitted by email prior to that class, will lower your grade: 2 points out of 100 points total for each absence, and 1 point of 100 points total for arriving 10 minutes late or later. Please review attendance, late-work, and related policies in the left-column on this page. Participation is graded by the quality of your contributions in class, mostly when randomly selected to (a) serve as a design critic responding to peer projects; and (b) present their work to the class for class critique.

Note: Each student will upload to the shared class folder evidence of completing the daily assignment. This means that if the class topic is, for example, "Mind Maps," you will upload your Mind Map(s) to the folder labeled "Mind Map" before the next class session. At the next class session, student names will be selected randomly, and the Mind Maps of those students selected will be considered in class. If your name is called in class and you are not present or your assignment is not submitted or you are not otherwise excused from class, you will lose 5 points of your 10-point "attendance and participation" grade.

10 points Completion of Cornell IRB training for human participant studies.
From the Cornell IRB CITI link, follow this path to select the training:
Take CITI Training > View Courses > "Role in Human Subject Research" [pulldown] Research Assistant and "Which courses do you plan to take?" [pull-down] Basic Human Subjects – Social & Behavioral Focus.

Email the completion certificate to the TA on or before our last class session before Thanksgiving break. Failure to complete this task or late submission results in a zero grade for this component of the course. No excuse.

10 points Ideation [Grading Rubric]; EXAMPLES 1, 2 from DEA 2730.
(1) upload to our shared folder and present in class PowerPoint slides (or pdf pages, if you use an application other than PowerPoint to make slides). These slides contain your one best example of each ideation strategy, 01-07 (see the upper-left of this webpage for the list of these). The one exception to the rule of "one best example": you will show 10 examples -- ten foil "rapid" prototypes -- for "04. Prototyping," Your last slide should be your (animated) GIF as simply an embedded file in your PowerPoint or a link (URL) to a video posted on Vimeo or YouTube. If you do not have a suitable Adobe product to create this print ad, is a free image and photo editing app for Windows.

10 points video of early demo with Grove [Grading Rubric]; EXAMPLES 1, 2, 3.
To create functioning, interactive prototypes, you are required to embed Grove electronics into your design (see the Grove Beginner Kit for Arduino User Manual).

Your prototype with embedded Grove modules will have at least 1 input and 1 output:

at least one Input (a sensor, such as a motion sensor or a light sensor)
at least one Output bit (an actuator, such as an LED or a servo motor).

Upload to our shared folder, using this Word doc template, a title for your demo that identifies your input(s) and output(s), a link (URL) to a video posted on Vimeo or YouTube of a "demo" of your working design using Grove (as it stands at this point in the semester) captured by video, and the code pasted into the same doc, where shown. Name this Word doc [My Name]-Grove-Demo.doc. The purpose of this video is to demonstrate your physical, interactive prototype with embedded, functioning Grove electronics. Show us something that works! The early prototype will be graded on a simple 10-point scale for overall quality.

10 points Concept [Grading Rubric] EXAMPLE 1.
In class, in a 3-minute presentation, you will "sell us" on your design concept, as if we were your clients or your investors. You can share slides with us -- slides showing whatever you judge will persuade us -- but you must make some physical manifestation of your design as part of your presentation. Ideally, this physical prototype, low to mid-fidelity, will be embedded with Grove electronics to demonstrate your interactive design. If you elect to show us slides, upload the slide file (pdf) ahead of the class presentation day as e file named, [your name]_presentation.pdf. Should you exceed the 3-minute time limit, we will cut you off at 3 minutes.

In addition to the 3-minute presentation (ungraded, but for participation), you are required to upload to our shared folder your Concept (Grading Rubric) as PowerPoint slides (or pdf pages, if you use an application other than PowerPoint to make slides):

Slide-1: a title slide with a name and logo for your prototype and a money shot.
Slide-2: your 08. Scenario in written text.
Slide-3: your 09. Role Play captured by video: provide URL link to Vimeo or YouTube.
Slide-4: your 10. Morphological Chart showing three paths for three alternatives.
Slide-5+: 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″). 

20 points Exam on key terms from this course up to the moment of the exam.
NOTE: I do not share my lecture slides. Come to class, read the short assigned readings, and become familiar with the basic terms of human centered design. If you do this, the exam will be very easy! For the exam, you will be provided a word bank of key terms and numbers (e.g., survey, 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, you would select from the word bank and enter focus group.)

(1) A poster [my guide], 30" wide x 40" high, communicating in a visually compelling format, 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.

You are strongly encouraged to learn from posters for ACM Late-Breaking (aka "Work in Progress") contributions found in the ACM DL as well as posters from previous DEA 2730 students and from my lab: home+, Xtinguish, Qora, Bag-of-Words, 1, 2, 3, 4. But please view my guide for detailed requirements, as the example posters may not contain all my poster requirements. I will grade your poster following my Rubric.

(2) A video [my 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 that is an mp4 file of < 30MB.

You are strongly encouraged to learn from videos presented at the start of almost every class session, many drawn from the ACM Demo Hour, as well as videos from previous DEA 2730 students and from my lab: Muncher, GrowBot, Xtinguish, ReWear; 5, 6 and, on the narrow left-column of this webpage, more DEA 2730 student videos. But please view my guide for detailed requirements, as the examples may not contain all my video requirements. I will grade your poster following my Rubric. My guide essentially communicates 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.

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] For your demo video, you may want to add a remote environment (e.g., a dorm lobby, the Cornell campus, a Parisian café, an assistive living unit, a museum lobby) as a preferred physical context for your design; however, such an environment is not always readily accessible to you. An easy strategy for adding this physical context is as follows: video record your working prototype (with “actors” or scale figures of people if your prototype is to-scale) on a white background (e.g. in front of a white wall); then, add your background context photo (e.g. a photo of the café) as a virtual background in Zoom and record your screen.

This course does not require the use of digital fabrication to produce the prototype. You can manually produce all deliverables for this class. Many students use Adobe Photoshop or a like app, but even this is not a course requirement.

It's however easy to digitally fabricate components for your prototypes. Our partners for this course are the staff or our very friendly and capable Digital Design Fabrication Studio ("D2FS") on LL2 in HEB adjoining MVR. D2FS staff in the shop in HEB 2L31.

• You can easily draw a 2D file of your component(s) for laser cutting by our D2FS staff. Use Adobe Illustrator (save as ai) or use a CAD program like SketchUp (save as DXF) which is free and very simple to use.

• Preparing files for 3D printing can be more difficult, but if they are simple geometries, you can again use SketchUp. If you need a more complex form, you might begin by seeking the file you need from repositories of 3D printing files like this one and this one.
If you need to create a form anew or modify an existing file, the standard application to do so in industrial design/architecture is Rhino, and in Engineering, Solidworks (both are available on the computer in the rear of the "Assembly Room,' HEB 2L32). Typically, files are saved as stl for 3D printing. Work with the D2FS staff on your 3D printing projects.

• Once you have saved your file for laser cutting (ai or DXF file) or 3D printing (stl file), "Request an Appointment" to submit your file and specifications for digital fabrication, and the staff will do the work for you, presenting to you ASAP the fabricated pieces you requested. Make sure to complete the online appointment form carefully with precise specifications. If laser-cutting sheet materials are not provided by the class (e.g. for assignment 2), you will need to provide the staff with these sheet materials to laser cut ahead of your request. 3D printing materials are supplied free of charge.

• Work with the D2FS staff ( - they are here to help you!
