course overview
this course • is about reliably building very good interactive systems. • this semester we focus on smart watch companion apps: apps that span both a mobile phone and a smart watch for increased availability and expressiveness. • the goal is to build a working interactive prototype. • we emphasize fieldwork, rapid prototyping and user testing to find the right design and avoid obvious and not-so-obvious mistakes.
Human-Computer Interaction (HCI) Human End-user of program Others (friends, collaborators, coworkers) Computer Machine program runs on Often split: clients & servers Interaction User tells the computer what they want Computer communicates results
User Interfaces (UIs) Part of application that allows People to interact with computer Computer to communicate results Can include hardware design Buttons, sliders, other sensors HCI = design, prototyping & evaluation of UIs http://www.reactable.com
Why Study User Interfaces? “The results show that in today's applications, an average of 48% of the code is devoted to the user interface portion. The average time spent on the user interface portion is 45% during the design phase, 50% during the implementation phase, and 37% during the maintenance phase.” – Myers & Rosson, CHI’92
Why Study User Interfaces? Major part of work for “real” programs (approx 50%) You will work on “real” software (intended for people other than yourself!) Bad user interfaces cost Money, Lives, Votes, … User interfaces hard to get right by intuition or modeling People are unpredictable
Why Y ou Should Care: The Dramatic 1995 American Airlines jet crashed into canyon wall, killing all aboard. On approach to Rozo airport in Colombia Pilot skipped some of the approach procedures Pilot typed in “R” and system completed full name of airport to Romeo Guidance system executed turn at low altitude to head for Romeo airport 9 seconds later plane struck canyon wall � Is the pilot to blame? � http://en.wikipedia.org/wiki/American_Airlines_Flight_965
Why Y ou Should Care: The Dramatic 7-Segment Displays [Thimbleby, 2013] • Air Inter Flight 148 • Medical Devices • Rescue Equipment
Why Y ou Should Care: The Mundane • Usability problems add up quickly • Many minor usability issues are “4 minute errors” • Two 4 minute errors per week, per person, on a team of 100 = ~one month of lost time/year • You owe it to your users to get these things right
Interface Design Cycle
Building Successful Interfaces 1. Task analysis & contextual inquiry 2. Rapid prototyping 3. Evaluation 4. Iteration (back to 1)
Task Analysis & Contextual Inquiry Observe existing practices Create scenarios of actual use CS247, Stanford, 2006 Create models to gain insight into work processes Key Concept: You are not the user! http://www-personal.umich.edu/~chrisli/m2.html
Rapid Prototyping Build a mock-up of design (or more!) Low fidelity techniques Paper sketches Cut, copy, paste Video segments Moggridge, Designing Interactions, p.704 Interactive prototyping tools HTML, Flash, Javascript, Visual Basic, C#, etc. UI builders Interface Builder, Visual Studio, NetBeans http://www.balsamiq.com/products/mockups/examples#wiki
Evaluation Evaluate analytically (no users) Test with real target users Low-cost techniques expert evaluation walkthroughs Higher cost Controlled usability study http://www.laurasmith.info/UsabilityTest.jpg
goals of the course Learn to design, prototype, evaluate interfaces Technology used to prototype & implement UI code Discover tasks of prospective users How to work together on a team project Cognitive/perceptual constraints that effect design Communicate your results to a group Techniques for evaluating an interface Many of these will be key aspects of your design future jobs Importance of iterative design for usability
CS160 and the CS Curriculum Most courses for learning algorithms and technology Compilers, operating systems, databases, etc. CS160 concerned with design, prototyping & evaluation We assume you are comfortable programming. Technology as a tool to evaluate design ideas via prototyping.

Samsung Galaxy Gear - A Long Time Coming smartwatches
8 things about smart watches http://theoatmeal.com/blog/apple_watch
8 things I learned from wearing an Apple Watch for a couple of weeks #1 : the apple watch will never replace your iphone #2 : battery life isn’t a problem #3 : the Taptic Engine could mean the death of the ring tone … #8 : this is the future
project theme : smart watch apps! mobile + smartphone companion apps � different kinds/numbers of sensors
project constraints theme : exploration, adventure, travel, … we will prototype apps for folks on-the-go apps must demonstrate communication between a phone and a watch you’ll have to prototype BOTH parts of the app during the term target users may not be overly broad, and may not include you! “college students” is way too broad of a group. consider “young mothers with children visiting Italy” or “the elderly at a museum”. must solve a real-world problem.
project platform: Moto 360 Smartwatch Android (Java) - emulators exist for this! I/O - pulse sensor, accelerometer, ambient light, 2 mics, circular screen, vibration motors plan on using your own phones : buy a cheap one if you need it (teams will be assigned so that each has at least one phone)
teams course staff will form groups at the end of week 1 4-5 students per team you’ll work with students with different skills/interests team project is cumulative go through an entire design process on one project
course mechanics this will work, somehow � http://cs160.valkyriesavage.com � office hours there � piazza link there � submissions via hackster.io
requirements you must be comfortable with programming individual programming assignments require you to write Java code using an Android dev environment. you must be able to attend one of the sections you must commit to working with your assigned team on your project

readings Readings are very important to the class Do the reading before class. Midterm will include topics only covered in readings Readings will be linked from web and bCourses. Online reading responses (ongoing assignment) You must post one substantial answer or comment per lecture, before class. You get 3 slip days for reading responses. Responses are a major factor in your class participation grade.
