Designers are researchers Designs are hypotheses

about what might be useful about how technology shapes cognition and

collaboration

- David Woods, 1998

Woods’ requirements for supporting cognitive work

Primary requirements: Support coordination Support resilience

Design requirements that support coordination and resilience: Observability/Visibility Directability Support for directing attention Support for shifting perspectives

How do you know…What cues matter?

What needs to be known or learnable?

What boundaries to present?

What controls handle the variety in the environment?

What navigation strategies to support?

What humans will expect?

What is too much user support?Collect Data; Evolve Design

Collect Data; Evolve Design

Chou, E., Venkatraman, V., Larson, K., Li, Y., Gibson, M., & Lee, J.D. (2014). Contextual design of a motivated medication management device. Ergonomics in Design: The Quarterly of Human Factors Applications, 22, 8-15.

Contextual Design ApproachThe flow model describes the roles, responsibilities, and

communication among stakeholders of the work.

The sequence model exposes the order of tasks and activities.

The artifact model illustrates the tools used or modified during work.

The cultural model depicts the social influences of the workplace.

The physical model outlines the visible layout and movement of work.

Chou et al., 2014, p. 10

To collect the data, we employed contextual inquiry, an interview-like activity based on the master–apprentice framework; designers approach the interview as apprentices and watch and learn from the user, who is the “master craftsman”. (Chou et al., 2014, p. 9)

This approach enabled the design team to observe medication management as it occurred within older adults’ daily routines. More important, participants verbalized their intents at each step, which provided the research team with valuable insight. (Chou et al., 2014, p. 9)
