1. What’s Different About User Experience Design for the Internet of Things?
How Is UX for IoT Different?Functionality Can Be Distributed Across Multiple Devices with Different CapabilitiesThe Focus of the User Experience May Be in the ServiceWe Don’t Expect Internet-Like Glitches from the Real WorldIoT is Largely AsynchronousCode Can Run in Many More PlacesDevices are Distributed in the Real WorldRemote Control and Automation are Programming-Like ActivitiesComplex Services Can Have Many Users, Multiple UIs, Many Devices, Many Rules and ApplicationsMany Differing Technical Standards Make Interoperability HardIoT is All About DataA Design Model for IoTUI/Visual DesignInteraction DesignInterusabilityIndustrial DesignService DesignConceptual ModelProductizationPlatform DesignSummary

A note on the digital index

A link in an index entry is displayed as the section title in which that entry appears. Because some sections have multiple index markers, it is not unusual for an entry to have several links to the same section. Clicking on any link will take you directly to the place in the text in which the marker appears.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
