It‘s a Brave New World…
 Are you afraid of losing control over your smart home?
 Why do you push bytes around the globe to turn on the
light?
 What do you think about installing a particular app for
every new task?
 How to let end users securely deal with the huge
number of everyday Internet of Things devices?
 How to economically build individual apps for a
heterogeneous device landscape?

Conclusion
 Web frontends for heterogeneous everyday devices
– End User Development: autonomous composition of IoT
applications with Web Components
– local data flows
 Interdisciplinary challenges
– HCI related: multiple devices, different input modalities
– economical: companies feel the urge to provide UIs to a
wide variety of end user devices
