Ma mission

« En se basant sur quelques notions simples d’Interaction design, vous donner

des pistes pour rendre votre application meilleure »

Make your app the user best friend

Make your app the user best friend

« Software should behave like a considerate human being »

About Face

« Je voudrais être considéré en tant que tel »

Make your app the user best friend It’s not harder to make a considerate app! Take an interest

Use common sense Self-confident

It’s not harder to make a considerate app Know your users Communicate with them using their language and idioms Be clear and direct Don’t stop the proceeding!

Take responsability Stop asking the user about every action If you fail to do something, try to fix it. Take decisions, but allow the user to have the final word

Mostly right, most of the time What’s best?

80% best scenario, 20% worst? Bother users 80% of the time for a 20% probability scenario?

Use the power of UNDO!

KISS

KISS Keep It Simple and Stupid

Right information at the right moment Don’t bother the user with a complicated UI

Use a « mostly right » default configuration

Too much stuff!

Muzei

Guess what the user would do next

Guess what the user would do next Learn from your users Observe them in real situations Use tools like Google Analytics Machine Learning

Eat your own food! Use the Cloud!

Chrome Custom tab Custom look Browser pre-warming in background

DNS resolution HTTPS/TLS negotiation

Smart apps

Put idle cycles to work (Google Keep, GCM) Have a memory

Smart apps

Put idle cycles to work Synchronize data in background Preserve battery and data quota

Use GcmTaskService to be smart!

Network typeBatteryTime/interval

Have a memory« If it’s worth the user entering, it’s worth the application

remembering »

Remember choices and defaults Remember patterns Remember past entered data

Use Shared Preferences for example

Improve your app search engine Keep recent search queries

History clearing option Multiple criterias when possible : places, people, date…

You know the user: give him personnalized suggestions Contextual suggestions : location, time…

Fail gracefully

Fail gracefully1. Have nice error messages2. Crashlytics (Fabric) / ACRA3. Thread.UncaughtExceptionHandler

Don’t burden the user with personal problems

Error message : the right way1. Don’t be sorry2. Explain the error in common terms3. Offer a solution

Be short and clear Be as less technical as possible

There is only one king

Among the best YES, design is hard, Good design is harder YES, you have to think hard to create a great app YES, it requires great skills

Conclusion Creating an app takes time Creating an astonishing app takes A LOT of time All apps are not meant to be great
