Abstract

Recently, wearable devices have gained popularity with familiar form factors and designs of eye-wear and watch to satisfy wearers' various preferences. Since UI/UX of smartphones can not be applied directly on smaller wearable devices, text entry on wearable devices is still problematic. In this paper, we first identify UI/UX problems of existing input methods and propose a new input method for wearable devices specifically targeting smartwatch platforms. We design and implement an efficient text entry method for wearable devices using trackball sensor and evaluate its performance and usability.

최근 사용자들의 취향을 고려하는 다양한 디자인을 내세워 기존의 안경, 시계 등의 친숙한 형태의 웨어러블 디바이스가 등장하면서 많은 인기를 얻고 있다. 하지만 착용이 가능한 초소형 디바이스라는 특성을 고려하지 않고 기존의 스마트폰 UI/UX를 적용하였기 때문에 작은 디스플레이 상에서 문자 입력이라는 문제점을 안고 있다. 이에 본 논문에서는 스마트워치와 같은 웨어러블 디바이스의 기존 입력 방법과 관련 연구들을 분석하여 UI/UX에 대한 문제점을 도출하고 스마트 워치를 위한 새로운 입력 방식을 제안한다. 이를 위해, 트랙볼 센서를 활용하여 웨어러블 디바이스에서 효율적인 문자 입력이 가능하도록 설계하고 구현한 결과를 통해 제안된 인터페이스의 유용성 및 성능을 검증한다.
