An on-screen keyboard for over-the-top set-top boxes using an open source operating system
Ying‐Wen Bai, Chi-Jung Lee · 2016
Currently when users use Over-The-Top (OTT) Set-top Boxes (STBs) to input text using a traditional QWERTY on-screen keyboard, users often spend most of their time to move their eye concentration between various keys. Thus, this paper proposes an on-screen keyboard for OTT STBs to be used with an open source operating system. This on-screen keyboard uses a three-step hierarchical design, so users can omit the steps of moving their focus between the various keys. This design allows users to reduce the number of button operations on the remote controller (RC), to speed up their text entry speed and to reduce their input time.
