Reflection

I love technology! I love how it helps people have a more enjoyable life!

Are there anything better than really make a difference through your own work to make the world a better place?!

In the next step - focus on how to enhance users' experience

1. Research & have a better understanding of the users

2. More emotional/enjoyable appearance design

3. Hi-Fi prototype
