The care and feeding of buttonsDaniel Stillman@dastillman

It’s difficult to have an epiphany if allyou want revealed is what youalready know.

Things I’ll talk about:

Buttons cost moneyShare your toysMix up your fidelitySuspension of disbeliefLather, rinse, repeat

A bit about me

One thing I do

My origin story.

My graduate thesis: it’s not easy toget a bike on a train.

Bikes take up too much room on thesubway.

Scooters are awesome but uncool.

Prototype one: size and shape.

Prototype two: deeper function.

Finally, mixed fidelity.

The users behind the process.

Where this work happened.

Buttons cost money

So do LEDs

$0.02 extra adds up fast A: SLIDER B: ONE BUTTON C: TWO ZONE BAR D: BUTTON BAR

$0.02 = how much awesome?

Share your toys

Touch screen e-ink tablet

What can we leverage or cram intothe existing space we have?

We made some toys…

And had a party…

And most of it sucked. Overall favorite Button favorite

And most of it sucked. Maximum score is 35 5 tasks X max. score of 7 per task

And most of it sucked.

Why did they like what they liked?too segmented Sweet Spot: Balanced Layering well segmented and Segmentation not segmented enough not layered enough well layered too layered

Can we do better?too segmented Surface ErgoTouch ClickTouch well segmented not segmented enough ThreeWheel TouchWheel PearlTouch not layered enough well layered too layered

Thankfully, the touch screen optionworked out.

Mix up your fidelity.

The pieces of the puzzle.

Step one – explore.

Flesh it out.

A lot of fast and cheap is good.

Suspension of disbeliefMix up your fidelity.

If you change everything…

Try a few things.

Prioritizing the requirements

Creating the primary workflows In order to provide better usability and comply with FDA HE75 Human Factors standards, we developed and tested distinct architectures.

Then gut-checking them

Washing Machine Interfaces.

Mapping user pathways

Mapping possible interfaces. Pure Physical Focus Hybrid Pure Touch ScreenOrdinal: traditional UI Screen with physical buttons Screen with touch buttons grid Screen with knob carousel Screen with knob Cover flow bulls eye breadcrumbs

Can we make it simpler? 1 2 3 4 5

Then we play with it, in place.

Get some pieces into place

Then put them in context.
