Thank you for your interest.
This is a badge with my work as its motif.
The work is called 'SMILE'.
'SMILE' is a robot who can analyze user's emotions. :)
if you smile at 'Smile' for a while, you will be able to receive a receipt for your emotion price.
You can see it on my blog.
** Unfortunately, it's written in Korean. but I think if you see a video on the blog, you can understand how it works.
