Role - Product & UI Designer

I worked with a partner who specialized in hardware and software implementation of Entag prototype and Android App. My task as the designer included form exploration, 3D modeling, post-processing, wireframing, UI design, and narrative-building.



This project was designed as a possible application of Korean Patent 10-2014-0128040 (Vibratory Gyroscope by Electrostatic Field, Agency for Defense Development), and selected as a winner for the 2015 Defence Startup Competition (hosted by Defence Acquisition Program Administration). 




Long work hour in office environment cause Forward Head Posture.  Forward Head Posture is a posture problem usually found in office workers due to extended use of computers and cellphones, lack of developed back muscle strength. We present Entag, a smart name tag for sitting posture correction. By using gyro sensor and low bluetooth energy pairing, the user can monitor and track his/her neck posture during work hours. Also with bluetooth device, security doors and computers can be automatically authorised even in low proximity.

Prototyping process

After sufficient amount of sketches, I modeled and printed the prototype using a SLA 3D printer. Then I post-processed the material with sand-blast and painted the prototype.  RFduino module, coin battery and generic gyro-sensor was inserted in the prototype.
