HCI PROCESS & THEORY • DARREN GERGLE, JEFFREY NICHOLS, AND JACOB O. WOBBROCK • DECEMBER 10, 2001

Welcome, Matt

Solid doors, made virtual.


Initial Conception

The Problem Lack of information passing between office

inhabitants and potential visitors, esp. when door closed Inability to understand state of office from hallway Inability to understand state of hallway from office

Door not best indicator of interruptability Office inhabitants may want to close door, yet

remain interruptable (e.g., for silence)


Why Doors?

Doors as media and mediators Doors are media

People can use their doors to express themselves to others

Doors are mediators Doors are gateways that limit person-to-person

interaction.


Today

Our Work Two studies of doors

Door Artifacts Door Actions

Brainstorming A list of design ideas

Implementation Door awareness system Door projector

Door Studies

A Study of Artifacts We looked at the artifacts on several

hundred doors around Carnegie Mellon.

A Study of Actions We spent seven hours observing hallways

and taking note of person-door interactions.


Studying Artifacts

Some doors

Art & Posters

Sign-up sheets

Lecture Announcement

Message board

Checkout list (on clipboard

)

Clock

Covered window (~80% of windows

seen)


Studying Artifacts, cont.

“Please do not slide papers

under my door”

“Please do not slide papers

under my door! Put

them on the chair.”

“Please do not move this chair”

An interesting door


Studying Actions

A Selection of Observations People glanced in doors as they walked down the

hall.

Person stopped in front of a door, tried to listen to activity in the office, but did not knock.

Person left their door open when they stepped out, to let an arriving visitor know they were going to be right back.

Person walked around outside an open door, to let the person inside the office know they were there.


Organizing Data

Step #1: Condense information into small chunks and group it appropriately


Organizing at Higher Levels

Step #2: Condense information into small chunks and group it appropriately

Developing Ideas

Brainstorming

Array of jornadas Sensors to tell what's behind the door Door access log Door projector State of door(s) at a distance (desktop app?) Projected window / muscle wire Privacy - abstract representation Virtual door – “door message from a distance” Physical tokens for interruption Ephemeral display (e.g., heat)


Physical Tokens of Interruption

1. Visitor walks up to a closed door.

2. Instead of knocking, they choose a token from the bin by the door.

3. The visitor pushes the token through the slot in the door.

4. The sound and motion of the token coming through the door may interrupt


Door Awareness

Doors have sensors to monitor their state(open, ajar, closed)

The state of the doors are broadcast on the net

What is the state of a given door?


Door Projector

Uses a door with a window

Image is projected onto the door, overlapping the window

Private/public display space
