BACKGROUND
While I was concentrating on my work, my mother told me that I had bad posture and I didn't realize it. Slouching is easy, yet maintaining good posture often requires a conscious effort.
Slouching is the leading culprit in causing back problems for more than 80% of Americans
As a sign of poor posture, it can lead to Neck pain, Back problems, promotes stress, and other aggravating conditions.
PROBLEM
It is hard for people to notice that their
posture is incorrect when they are concentrating.
IDEATION
CAT ON MY DESK
As a pet lover, I came up with this desktop cutie that can detect posture and provide feedback to help users maintain correct posture while providing emotional comfort.
NARRATIVE
My initial idea was to use the camera on the computer to detect the user's posture
as input, then use servo rotation and sound as output to achieve interaction
PROYOTYPE - V1 & V2
I tested it on people who complain about bad posture, they were excited about the idea, however, they felt the interaction experience could be improved.
ITERATION
I decided to add expressions with sounds to make it more emotional
and provide users with a more diverse interaction experience.
ITERATION ON PROTOTYPE
Interaction via light or distance sensors only
Posture monitoring is achieved through machine learning, with prompt sound and servo rotation
Different expressions according to the detected postures, with a variety of prompting sounds
PROCESSING
Teachable Machine & P5
Detect user‘s posture and sends data to other parts
(Training by different users' postures to make detection more accurate)
P5 connects tramontana & Arduino, also outputs model data
Arduino & Tramontana
Control the servo
Play GIF and sounds on the phone
IDEATION
How will Loki emote?
I designed three expressions corresponding to different states and provide users with timely feedback, while enhancing the interaction experience by adding emotional sensation
Types of Emotion
When the user's posture is incorrect, Loki will make an angry face and warning sound, when the user back to the correct posture, he will switch to the happy expression with rewarding sound, after holding it correctly for 3 Secs Loki will back to the normal status.
