While the user-centered design methods we bring from human-computer interaction to
ubicomp help sketch ideas and refine prototypes, few tools or techniques help explore …

This paper introduces a set of concepts for user-centered design methodologies that apply
to mobile and multi-device applications. It ranges from initial data gathering and …

Opportunistic practices can accelerate and simplify ubiquitous computing systems design.
Such practices may include copying and pasting code from online forums into one's own …

In this paper, we describe why designers need to look beyond the twin aims of designing for
the'typical'user and designing" prostheses." Making accessible interfaces for older people is …

We describe a new method for use in the process of co-designing technologies with users
called technology probes. Technology probes are simple, flexible, adaptable technologies …

In this paper we describe a case study of Universal Design applied to mobile phone physical
devices. Using a user-centered design process, we tried to integrate visually-impaired …

Designers of mobile applications have long understood that mobile devices are operated
within a context of significant constraints and environmental distractions. Despite this …

We describe the design and implementation of Photobox, a device intended to be used over
many years, which occasionally prints a randomly selected photo from the owner's Flickr …

A growing social problem in the US and elsewhere is supporting older adults who want to
continue living independently as opposed to moving to an institutional care setting. The …

Design patterns are a format for capturing and sharing design knowledge. In this paper, we
look at a new domain for design patterns, namely ubiquitous computing. The overall goal of …
