CordDial: Tangible User Interface for Tablet (2016 — 2018)

To augment touch interaction on tablet, I proposed CordDial, which is a dial-shaped object connected to an anchor via elastic cord. This dial had two conductive touch points, so a tablet could sense its position and rotation. Also, elastic cord could lead user to perform various interaction such as pulling the dial, pinching the cord, or sliding on it.
This project was presented in a poster session at the Ergonomics Society of Korea conference in 2016 and in a paper session at the Korea Human-Computer Interaction conference in 2018. Also, I got help from Hyungmin Kang to implement musical application with CordDial (this part was not published.)

PUPPIT (2016)

Project to raise pets well for beginner pet owners. To investigate the experience with a pet for beginner pet owners, various qualitative study methods were applied: literature analysis, interview with pet experts (a pet shop and vet), and semi-structured interview, personal inventory, camera journey with two pet owners. The questions during the interview were based on a literature analysis of four books about raising a pet. As a result, we found that people can’t feel how big the problem of raising before they adopt a puppy. Therefore, we aimed to design ‘Puppit’, a service before adopting a pet. This service was based on IoT devices; a smartphone application to notify important and regular events with a pet (e.g., walk with a dog, shower), and an AR app via smartglasses and tangible appcessories to provide an experience with a virtual pet on user’s home. This project was presented in a poster at the Ergonomics Society of Korea 2017 conference. Members: Youngeun Song, Haebin Lee, Gwangyoung Lee, Jaehee Lee Advisor: Prof. Hwajung Hong

Undergraduate

20Heals (2013)

Many people are suffered from mental stress nowadays, so we proposed ‘20Heals’ to relieve the stress. 20Heals tracked smartphone activity to catch the mental state of a user and provide proper phrases to reduce their stress. This concept was extracted from an interview with 2 teenagers and 12 twenties. The form factor reflects retro phone design with wood and mood lights to give a comfortable perception to the user. We used Arduino to implement the concept to communicate with the user’s smartphone. This was our graduation project :)

Glasses frame chart (2013)

We tried to make usable glasses frame chart to help people select their glasses frame. To do this, we took photos of 9 different glasses frame with a mannequin. We showed these photos to experiment participants and they filled a questionnaire about their perception. A 7-point Likert scale with bi-polar adjectives were applied to the questionnaire. After that, we analyzed the result based on PCA analysis and extracted the mapping of the glasses frames shapes and their perception.

UNIST Food On delivery (UFOd, 2013)

UNIST is far from downtown so there was some difficulty to order delivery food before delivery apps were popularized. Therefore, we interviewed stakeholders such as owners of famous delivery professional restaurants and students who frequently order food on delivery. Based on their needs, we proposed a new delivery system specified for a remote campus environment. We got an award from the Ergonomics Society of Korea by this project: “스마트 폰을 활용한 음식 예약 배달 및 배달 현황 조회 시스템(Blueboard)에 대한 UX 평가” (Authors: Youngeun Song, Myunwoo Lee). I got help from Jiyoun Han to implement the demonstration app of UFOd.

UI/UX design for manual dexterity disabilities (2012-2013)

We compared the accessibility of Android-based smartphones and tablets for manual dexterity disabilities. To do this, we interviewed people who had this type of disability and analyzed the video that contained their performance on daily activities such as phone calls or sending messages. Based on their extracted needs, we suggested an improved UI/UX design guideline for manual dexterity disabilities. This project was sponsored by Samsung Electronics.
