This invention focuses on UI solution to improve legibility of text information displayed in a small screen of home audio devices distant from user or possibly user with visual impairment in close range. The idea is to magnify the "text information of interest" such as highlighted text while keeping the usability quality of the interaction with the device.
Audio market trend is moving fast forward to network audios and built-in big storage space where vast amount of information has to be handled. These new audio devices will either have to use TV or its own high-resolution built-in screen to present such information that are more than merely song title or track number from audio disc like CD (e.g. folder navigation of network HDD, internet radio stations all over the world).
The invention provides a way to overcome readability issues of small display screens on remote controlled electronic devices. As remote-controlled domestic electronic devices grow in functionality, their component electronic information displays are required to display increasing amounts of information. These displays are often small, and can be difficult to read by users with vision problems, or by any users at a distance.
The problem this invention focuses on has been around sometime but wasn't raised as critical issue until recently. Traditionally audio devices have dot-matrix screens where text information like song title or track number of the audio disc is displayed.
However, future audio devices with mass amount of storage (such as audio devices with internal HDD that can store thousands of music files) and network capability (such as DLNA-based media playback, Internet radio, streaming audio from network services) will require high resolution screen (e.g. LCD screen with 800*600 resolution) as more information has to be handled.
As an alternative to equipping its own display screen, many audio devices utilize big screen like TV connected to them as an answer to this requirement. While TV is definitely a good option, there's an usability issue. User has to turn on TV and change TV source to the connected audio device. This becomes troublesome because (1) it requires several interaction steps user has to go through and (2) even when user wants to listen to audio only user still has to turn on TV.
A built-in high-resolution screen will help user to interact with audio device without having to have TV switched on. However, there's legibility issue in this approach. Unlike mobile phone or computer monitor, user generally does not interact with audio device within arm-reachable distance. Chances are, user is distant from the device and hold a remote control to interact with it. When user is distance from the device, the text information displayed in its built-in screen will be hard to read; in other words its legibility reduces. Consequently there's a need for an UI solution to improve legibility of this text information while...
