INTRODUCTION Chromecast [2] is a small HDMI device that provides HURDLES TO A SUCCESSFUL SETUP EXPERIENCE users with an easy way to stream online videos and music We will describe four hurdles that could interfere with a to the TV.

YouTube, Netflix, Pandora, and HBO Go. It looks like a flash drive. The Chromecast out-of-box experience (OOBE) has been At first glance, Chromecast could be mistaken for a USB lauded by reviewers [3] [4] and consumers [1] for its flash drive. Moreover, HDMI and USB cables and ports simplicity and ease of use. Even though setting up can look very similar to users. During our research, we Chromecast is pretty simple, we found that without found that some research participants assumed that proper guidance there were several ways that users could Chromecast needed to be connected to a computer and fail. This case study will present the different challenges not a TV. Some participants would try to force the the team faced in designing the Chromecast OOBE and Chromecast into a laptop’s USB port. When they were the different options the team explored. We will unable to do that, some of these participants would describe four hurdles: Chromecast’s resemblance to a connect the Chromecast to the USB cable and then flash drive, users’ reluctance to read setup instructions, connect the USB cable to the laptop. These participants users’ unfamiliarity with switching inputs, and would continue through setup this way and then wonder why they were not seeing any feedback on the TV. For Permission to make digital or hard copies of all or part of this work for these participants, it was very hard to understand that personal or classroom use is granted without fee provided that copies are Chromecast worked wirelessly and even though it not made or distributed for profit or commercial advantage and that copies “connects” to laptops and mobile devices, it did not need bear this notice and the full citation on the first page.

To mediate specific permission and/or a fee. this misconception, we iterated on the design of the TV in TVX’14, June 25 – June 27, 2014, Newcastle, UK. our instructional diagrams (so that it clearly looked like a Copyright 2014 ACM 978-1-XXXX-XXXX-X/XX/XX...$10.00. high definition TV) and labeled it as such. Users don’t like to read setup instructions. we conducted 57 usability research sessions in the lab, We initially included a detailed quick start guide to assist analyzed over 1700 survey responses from Google users in setting up Chromecast. However, we found that employees, and conducted 14 home visits with Google participants were not referring to it. We simplified the employees where we watched them set up and use the instructions but still found that users were relying on their product in their own homes. own intuitions to set up the device. We decided to experiment with putting the setup instructions right on the CONCLUSION lid of the packaging (see Figure 1). By doing so, we Chromecast is an easy product to set up and use due to a found participants were more likely to give them carefully crafted out-of-box experience. We relied on a attention and less likely to make critical errors. By fast-paced iterative design and research process that placing the instructions on the lid, a user could not miss involved key stakeholders from different disciplines. them, misplace them, or toss them away. Through this process, we were able to identify and resolve four key hurdles to successfully setting up the product.

Our designers would design a component of the product, our engineers would build it, and our researchers would test it in the lab. After each round of research, we would schedule debrief meetings (either the same day or next day) with the entire team to go through what we all saw in the lab and discuss how we were going to resolve the issues we saw during that round of research. We iterated until we were sure we had implemented the correct solution. We also heavily relied on feedback from Google employees using the product in their own homes.
