An introductory crash course on negotiation basics, principled methods developed in academia and honed in industry, and time-tested “getting to yes” tactics. Recommended prep: Negotiation Scene: Nightcrawler HBR: Getting to Si, Ja, Oui, Hai, and Da TED: William Ury: The walk from “no” to “yes” This lecture will be given by Hugo Van Vuuren.  Hugo is a...

Bias and prejudice are pervasive. What can we do as technologists to ensure that we  (as humanity) act fairly despite our biases and prejudices? I will also try to convince you that–as designers–we frequently make choices that systematically discriminate against certain populations. This is an inadvertent, but inevitable result of the current design practice for digital...

If you were able to launch your own visual search experiment, bring the data. If not, I will have something for you to work with.  On Tuesday, I told you about statistical analysis.  During this class, you will have a chance to practice it on your own. No readings. Worksheet for today’s class. Bring...

We will continue the activity we started during Lecture 19.  Plan on taking 30-45 minutes to finish your experiment.  We will spend the rest of the class taking each others’ experiments, giving feedback, revising and posting to friends! Bring laptops! No readings.

So it looks like one of the conditions in your experiment is resulting in different performance than the other.  Is it random noise or is it informative signal?  How do you know?  In this class you will learn the basic statistical techniques for answering these questions.  You will get to practice these skills during...

Using TELLab, you will design and implement an online experiment to test some hypothesis of your own design related to visual search.Quantitative experiments (e.g., A/B tests) are great, but they are actually very hard to design such that the data can be trusted. In the process of designing your own experiment, you will learn...

We will discuss how to use github and how you can use Dreamhost to host your applications. Required prep: Create a github education account (with your harvard email address) on education.github.com (you first need a regular github account with your harvard email address and then click on “get pack” to connect your account with github education). The github education account...

We will continue the dive into low level human abilities.  This time we will take a look at human visual perception and its implications for user interface design.   Required prep (post your written response before class): Benway, J. P., & Lane, D. M. (1998). Banner Blindness: Web Searchers Often Miss “Obvious” Links. Internetworking: ITG Newsletter,...

We will dive deep into low level aspects of human neuromotor system.  From there, we will discover Fitts’ law, which will give us the superpower to make quantitative predictions about how much time people would need to perform basic tasks with different interface designs.  Along the way, we will empirically (and then analytically) answer...
