Overview • Introduction • Hanger Display • Evaluation • Results • Design Considerations 2
Introduction • One goal of ubiquitous computing: • To support natural interaction technology • One common solution: • Digitally augment everyday objects that have well-established functions and meanings • Our project: • Explore how sets of everyday, physical artifacts can collectivelyprovide an information display or interactive behavior 3
Collections as Interfaces • Distinction from previous work in collections: • Everyday artifacts are individually meaningful entities to start with • Reasons to explore this approach: • Use of everyday context • Collections take advantage of spatial arrangement • Many collections naturally exist 4
Case Study: The Hanger Display • Designed and implemented a generic interface consisting of a collection of augmented hangers on a rod • Implemented three peripheral display applications for the Hanger Display • Collected formative user feedback 5
The Hanger Display • Each hanger has LED attached • Hangers form a row of LEDs • Lighting of LEDs can mean different things (many possible inputs) • Three peripheral display inputs: • Temperature • Barometric pressure • Remote presence 7
Design: Why Hangers? • Common objects in the home, naturally formed into collections • Hangers associated with • hanging up and picking out clothes • morning rituals • getting ready for work or the day • During these activities, people are interested in easy access to related information: • weather or their schedule to determine what to wear • amount of email as an indication of how much work there is to do • traffic to give an indication of commute time 8
Design: Why Hangers? • Affordances • When hanger is hung on rod, it is “part of the application” • Reduces the need for dedicated devices • Hangers are already part of morning activity; why not make them more useful? 9
Challenges • Preserve natural interaction • Technology cannot interfere with everyday use of hangers. • People will want to move, add, and remove hangers. • Resiliency to change • Everyday use should not interfere with the technology (i.e., it should not “break” the application). 10
Implementation • Power and data supplied to LEDs via rod using MicroLAN protocol • Java software on a laptop controls hanger LEDs • Simple, cheap technology • Resilient to change 11
Formative Evaluation • In-lab, 8 participants • Purpose: • Obtain feedback on the concept of everyday object collections as interfaces • Method: • Showed three applications to demonstrate Hanger Display • Informally interacted with display • Interview: qualitative feedback • Brainstorm: new applications and interaction 12
Results • Realistic use for such displays: all users suggested applications they would use • Many suggestions involved more interaction, something afforded by physical collections • Points to new, creative, and useful applications of ubiquitous computing that support activities in situ 13

Design Considerations • Existing structures can be useful in defining interface scope • Interfaces composed of everyday artifacts must be resilient to change • This type of physical interface could lead to new interaction possibilities 16
Conclusion • Explored how sets of everyday, physical artifacts can collectively provide an information display or interactive behavior • Benefits of everyday object collections as interfaces: • Everyday objects provide opportunities for useful applications that support activities in situ • Collections take advantage of spatial arrangement • Designed and implemented The Hanger Display as a case study • Confirmed design considerations for such interfaces 17
