设计考虑
• 分辨率 Resolution:	
• HD Ready = 720p = 1280x720	
• Full HD = 1080p = 1920x1080	
	
• 观看距离 viewing distance:	
• 30” – 3m	
• 40" – 4m	
• 50" – 5m	
	
电视屏幕	
 设计考虑	
•  少即是多:电视屏幕很⼤大,可是观看
距离远。(⼀一个远距离观看的电视和
⼀一个近距离使⽤用的⼿手机没什么不同)	
•  横向布局更符合电视宽屏。	
•  深⾊色背景上的浅⾊色内容更易读。	
•  字体要⾜足够⼤大,⽅方便阅读。	
•  ⽂文字和背景对⽐比明显。	
•  任何时候,聚焦框/聚焦元素明显。	
•  电视的优势在于对⼤大图像,视频及⾳音
频的展⽰示,利⽤用这些优势。	
•  图像⾜足够清晰,避免锯齿。
设计考虑	
 红外摇控器	
•  ⼀一切内容⽤用遥控器⽅方向键可访问: 上,
下, 左, 右 ,确定, 返回。	
•  避免⽤用户输⼊入⽂文字。 	
•  电视与⽤用户之间有⼀一定距离,唯⼀一的
媒介是摇控器,⽽而红外传输有⼀一定延
时,需要:	
- 保证对⽤用户操作的快响应性。	
- 避免使⽤用需要点击才能交互的元素: 	
如下拉列表,不点击内容即不可⻅见; 	
⼜又如滚动条,遥控器⽆无法拖曳。

从个⼈人到⼤大家	
Me -> We
•  电视主要⽤用来娱乐休闲的,⽤用户不希
望有太多的交互及决策。	
•  电视是公共设备,控制隐私的能⼒力有
限。需提供功能⽅方便⽤用户清除历史纪
录。	
•  避免输⼊入可以提供桌⾯面⺴⽹网⻚页让⽤用户输
⼊入信息,然后将帐户很⽅方便地链接到
电视上。	
•  从个⼈人到⼤大家(me->we)的转变,除
了视频⾳音频应⽤用外,社交分享类,教
育类,多⼈人交互的游戏类应⽤用也适合
开发为电视应⽤用程序。

Opera电视应⽤用商店	
•  基于 HTML5,针对电视宽屏及摇控器操作进⾏行了优化	
	
•  云架构平台,展⽰示及管理各种电视应⽤用:	
-  个⼈人⾸首⻚页: My Apps	
-  应⽤用商店: TV Store	
	
•  跨平台,运⾏行于Opera Devices SDK 3.1及其以上
