UX is not
Dessiner de jolies interfaces trop dans le vent
Appliquer des principes ergonomiques à la pelle
Que le buzzword marketeux web de l’année
Rendre tout facile et intuitif

What is UX ?
Contexte = immersion plus ou moins complète / exclusive, immersive
UX design is « entirely » focused on solving the users’ problems
L’expérience ne se limite pas à l’usage d’un dispositif numérique
(qu’elle qu’en soit la nature)
il faut la considérer comme un continuum :
un avant / un pendant / un après
0. Tout est question de contexte

What is UX ?
1. Meet the users’ needs

et de la proposition initiale.

when a user clicks on something, he’ll need a response
from the product to understand that his command has been
received.
Feedback is a crucial way to encourage communication
between humans and machines.

of our key goals as designers.

Focus UX > User Control
1. users tend to lose track of their position and orientation in the real world
2. movements in the virtual world are minified = that is, bigger movements in the real world
translates to smaller movements in the virtual world.
Verbatim :
“It was a bit disorienting because I had expected to be facing the other way.”
“I thought I was just maybe (at a) 0–20 degree angle but I was like at 45.”
Spatial disorientation

Focus UX > User Control
Keep endings open
consider keeping the scene and let the users decide for themselves when they are ready
to take off the head-mounted display. This gives them more control over the exit.

Apply soft transitions
