Project brief

Designed for the seconds that matter.

How can an emergency interaction stay useful when a phone, network connection or conventional support may not be available?

Challenge

In an emergency, a phone may be damaged, out of power, difficult to reach or too complicated to operate under stress. The interaction needed to be immediate, visible and physically dependable.

Design response

Research shaped a simple two-mode system for Danger and Medical situations. Large controls, a protective lid, visible SOS lighting and a screenless wrist-worn form reduce the number of decisions a user has to make.

Outcome

The final direction was translated into a detailed interaction model, a visual system and a 3D-printed physical prototype that could be demonstrated and evaluated.

Process

Four decisions. One emergency route.

Four moves connect the problem, the design logic and the final direction.

01

Understand the failure point

Assume the phone, signal or conventional help may fail.

02

Reduce the decision load

Organise urgent action around two clear modes: Danger and Medical.

03

Make intent physical

Use deliberate controls, a protective lid and visible SOS feedback.

04

Bring it to the wrist

Move from the early forearm concept to a more familiar wrist-worn form.

Media

See the response before it is needed.

The moving pieces make the project easier to understand at a glance.
