As part of an ongoing effort to understand ease of use of digital home technologies, we undertook an exploratory study of people who use their home networks for more than just broadband Internet access. In particular, we wanted to understand the overhead, or problem-time, people spent with their home network devices. As expected, we saw issues of broken hardware and broken software. We also found that problems are often caused by broken expectations, a mismatch between what a person expects to be able to do and specific device capabilities. In this paper we explore broken expectations in the digital home with examples from our study. These observations suggest further research into the ways user expectations and activities shape the digital home experience.

“…Researchers have also explored infrastructures that span ad hoc collections of devices [13,14,16,17,22]. Most of this work focused on allowing users to improve interaction with their personal mobile devices by temporarily annexing devices in the local environment, but some also explored how to allow users to collaborate by temporarily combining the resources of their physically proximate devices.…”

An infrastructure for extending applications' user experiences across multiple personal devices

Users increasingly interact with a heterogeneous collection of computing devices. The applications that users employ on those devices, however, still largely provide user experiences that assume the use of a single computer. This failure is due in part to the difficulty of creating user experiences that span multiple devices, particularly the need to manage identifying, connecting to, and communicating with other devices. In this paper we present an infrastructure based on instant messaging that simplifies adding that additional functionality to applications. Our infrastructure elevates device ownership to a first class property, allowing developers to provide functionality that spans personal devices without writing code to manage users' devices or establish connections among them. It also provides simple mechanisms for applications to send information, events, or commands between a user's devices. We demonstrate the effectiveness of our infrastructure by presenting a set of sample applications built with it and a user study demonstrating that developers new to the infrastructure can implement all of the cross-device functionality for three applications in, on average, less than two and a half hours.We set out to reduce that barrier by creating an infrastructure that developers can use to allow their applications to easily exchange information, events, and commands across a user's devices. While there are other infrastructures that support the development of applications that span multiple devices in general, our infrastructure differs from them by explicitly focusing on supporting applications that span personal devices.More concretely, our infrastructure elevates device ownership (or more broadly primary use, because users may employ devices owned by other entities, such as their companies) to a first class property and uses it to organize communication among devices. Ownership is a useful organizing relationship because, unlike other potential relationships such as physical proximity, it implicitly incorporates information about access permissions. Ownership is also stable over time, changing over months or years rather than hours or days.

When users want to combine various resources in an ambient intelligent environment in an ad hoc manner, they need to be able to identify and select these resources. We conducted an experiment to study various user interaction styles for combining input and output devices in an ambient intelligent environment. The results show that the test subjects prefer to press a designated button on a device to select it. They least prefer an automatic selection. The main conclusion is that our subjects are willing to spend a bit of time and effort in order to gain control over their environment. This supports the claim that users acting in ambient intelligent environments should always be kept in the loop; systems should take care not to alienate their users when making decisions for them.
