Abstract

当用户观看(个人录像机中的)节目上可得到的信息时,确定是否节目要被录制的关键词被突出。这可以通过使用原文的大小或者通过使用颜色或者任何其它种类的不同突出-即加框或使文字闪烁而实现。这使用户容易识别在他们的个性化特征文件中使用的关键词。此外,用户还能在关键词之间漫游,改变关键词的突出,以指出关键词的(多个层次的)评级。

Description

用于提供用户界面的方法和装置

本发明涉及用于一种提供用于显示包含至少一个符号的信息单元 的用户界面的方法。

本发明也涉及一种计算机程序,它使处理器能执行该提供用于显 示包含至少一个符号的信息单元的用户界面的方法。

本发明也涉及一种携带计算机程序的可触及的介质。

本发明也涉及一种携带计算机程序的信号。

本发明也涉及用于一种提供用于显示包含至少一个符号的信息单 元的用户界面的装置。

在典型的个人视频录像机(例如TiVo、 R印layTV)中,用户能请 求节目中的信息,诸如标题、种类和概要。此外,用户还能给节目一 个评级。将这个评级输入一个个性化特征文件。这个个性化特征文件 一般是以特定关键词的评级为基础的。如果在节目的描述(也称元数 据(metadata))中出现与这些关键词匹配的词语或像面部那样的符 号,则系统中的录制代理将用那些关键词的评级来确定是否要录制这 个节目。

当用户观看被录制节目的可用信息时,他不能立即确定系统为什 么已经录制了或将要录制一个特定节目。而且,用户不能直接影响在 个性化特征文件中使用的关键词的评级,并且不能得到关于在个性化 特征文件中使用的关键词的反馈。

本发明的目的是改善对因确定某节目已经被录制还是将要被录制 所使用的关键词的反馈。

这个目的是通过按照本发明的方法实现的,其中,该方法包含以 下步骤:将符号与个性化特征文件中包含的至少一个关键词作比较, 其中该关键词与一个评级相关联;在显示信息单元的同时,突出 (accentuate )与关键词匹配的符号,所述突出(accentuation )对 应于与关键词相关联的评级。

当用户观看节目上可得到的信息时,确定是否将要录制某节目的 关键词被突出。这可以通过使用原文的大小或者通过使用颜色或者任 何其它种类的不同突出-即加框或使文字闪烁而实现。这使用户容易 识别在他们的个性化特征文件中使用的关键词。

本发明的一个实施例进一步包含以下步骤:通过用户可操作的输 入装置改变被信息单元包含的符号的突出;改变个性化特征文件以包 含一个对应于所述符号的关键词;将该关键词与一个评级相关联,该 评级对应于所述符号的突出。

此外,用户还能在被突出的关键词之间漫游,改变关键词的突出 (例如大小),以指出其对关键词所代表的主题的(多个层次的)好 恶。这然后被用作个性化特征文件的直接输入。

用于启动处理器的计算机程序使处理器能执行按照权利要求1的 方法。

携带按照本发明的计算机程序的可触及介质携带按照权利要求2 的计算机程序。

携带计算机程序的信号携带按照权利要求3的计算机程序。 按照本发明的装置包含用于将符号与个性化特征文件中包含的至 少一个关键词比较的装置,其中该关键词具有与其相关联的评级;和 在显示信息单元的同时用于突出与关键词匹配的符号的装置,该突出 对应于与关键词相关联的评级。 附图说明

现在将通过以下附图更详细地说明本发明及其实施例。 图1表示按照本发明的方法的一个实施例的实现;和 图2表示按照本发明的装置的一个实施例的设置。 具体实施方式

当用户观看节目上可得到的信息105时,确定是否将要录制某节 目的关键词被突出。这可以通过使用原文的大小或者通过使用颜色或 者任何其它种类的不同突出-即加框或使文字闪烁而实现。这使用户 容易识别在他们的个性化特征文件中使用的关键词。

此外,用户还能在被突出的关键词之间漫游,并改变关键词的 突出(例如大小),以指出其对关键词所代表的主题的(多个层次的) 好恶。这然后被用作个性化特征文件的直接输入。例如,如果用户 欣赏烹调节目,他可以将烹调节目的说明中的烹调关键词110放大 (见图1:节目信息)。系统于是知道该用户喜欢烹调节目,因此相 应地调整个性化特征文件。相反的过程适用于用户不喜欢中餐烹调

小中餐关键词120。使用这个特征功能的额外好 处是在个性化特征文件中可以获得更大的量化度(granularity), 例如,用户可能对关于融合烹调(fusion cooking)的节目喜欢更 甚于一般的烹调节目。使用相同系统的其它用户可能不喜欢烹调。 所以当他们观看相同的节目信息时,可以将"烹调,,关键词缩小。 因为每个用户有其自己的特征文件,所以每个用户都能规定其对关 键词的评级。

除了突出节目说明中的关键词,系统也能例如通过使用颜色、加 下划线或总体赋予类似的外观(当然是与说明中其它词语不同的外 观)来显示关键词之间的关系,然后用户可以在这些关键词之间改变 这种突出。所以,例如在图1中,用户能放大词语"胖,,130但是不 放大"两个胖女士" 140以表明他要对关鍵词"胖"给予高的评级, 但不是对"两个胖女士"的节目整体。这允许用户对上下文中的关键 词评级。按照本发明的方法的实施例使用的其它情况是:

纽:

可以突出在节目的字幕中出现的关键词(高亮度、粗体等等)。 这样,用户立即认识到为什么该节目被系统选择用于录制。 Ceefax二

适合PVR系统中的元数据的同样也适合于Ceefax上的节目信息, 可以突出Ceefax上的节目说明;附加的好处是用户 一眼就能看出节 目的内容是什么。

网页:

在网页中的使用特别有意思。如杲在搜索引擎中将该概念应用于 网页,则它就能被用于执行精细的搜索。所以,用户不但立即知道为 什么结果中返回某页,也能改变关键词的重要性(例如通过改变其大 小、高亮显示等)来改进搜索。在本发明的另一个实施例中, 一个软 件模块能向用户显示关于节目的信息,突出在个性化特征文件中使用 的关键词。突出的程度由关键词在个性化特征文件中具有的评级决 定。软件模块能允许用户选择关键词和改变突出的程度来指示该关键 词所代表的主题的评级。

该应用可以是用于如图2中所示的用个性化特征文件和评级作为 自动录制的根据的所有类型的录像机或机顶盒的用户界面。用户界面

由个人录像机201生成,并通过在链路204上提供信号203而被电视 机202显示。
