• Contemporary computing systems are single-user and task-oriented• much work is collaborative• many applications and resources are used in an activity
• Handling parallel work and interruptions is hard• manual and metal overhead• resumption is difficult
• People think of their work in “activities”• not in terms of files, folders, documents, etc.
MotivationMotivation from previous research

Motivation
• to create computer support for human activities• for clinicians working in a hospital• managing
• multi-tasking ~ many parallel activities • mobility ~ in space and between devices• collaboration ~ coordination, communication• urgency ~ time-critical work

Computational Activity. An aggregation of services, resources, artifacts, and users that are relevant for a real world human activity.
Activity-Based Computing. A computing infrastructure, which supports users to create, save, manage, suspend, resume, move, share, and discover computational activities.
Activity-Based Computing
1. Activity-centered resource aggregation2. Activity suspension and resumption3. Activity roaming4. Activity sharing5. Activity awareness

Activity-Based Computing
1. Activity-centered resource aggregation
10-04-23 · 10
• Supports handling the huge data sets in clinical work
• An Activity integrates related services and data
Activity-Based Computing
• Supports handling many concurrent work activities, multi-tasking, and many different patient cases
• An Activity can be suspended and later resumed
2. Activity suspension and resumption
10-04-23 · 11
Activity-Based Computing
•Supports the mobile nature of clinical work•An Activity can be resumed “anywhere”
3. Activity roaming
10-04-23 · 12
Activity-Based Computing
•Supports the collaborative nature of clinical work
•An Activity has a set of participants who can work on it taking turns or at the same time
4. Activity Sharing
10-04-23 · 13
Activity-Based Computing
• Supports the physical nature of clinical work• An activity is aware of the users’ real world

Experiments and Evaluation
10-04-23 · 20
• Scenario-based evaluation• clinical work• in a simulated hospital ward
• ABC-aware clinical applications• medicine schema, record, patients, charts, images, ...
• Scenarios• morning conference, ward round, follow-up, radiology
conference, medicine administration
