Modeling the wear of digital object

尽管我们可能没有意识到这一点，但在我们的日常生活中，穿戴是一个真正重要的信息来源。通过佩戴，我们可以感知到我们使用物品的历史，这种方式可以为我们正在做的任务提供信息和支持。在这项研究中，我们开发了一种使用物理磨损效应可视化桌面对象历史的技术。虽然在现实世界中，文档和文件夹在重复使用后通常会被弄脏或被撕毁，但现有图形用户界面系统中的文档和文件夹图标永远不会随着相应数字对象的使用而改变其外观。在真实的办公环境中，穿戴始终是支撑上班族日常工作的重要信息来源。例如，为了找到经常引用的文档，他/她可能会自然而然地先用手拿起一个相对磨损的文件夹，因为频繁使用该文件夹往往会弄脏和弄脏它。此外，为了找到最近使用的文档，工人不会检查覆盖着厚重灰尘的文档堆栈，而为了搜索最近创建的文档，他/她将跳过其纸张已经变质的那些文档。因此，通过使文件和文件夹图标根据它们的历史改变它们的外观，用户能够感知和使用图形用户界面上的磨损负担，并直接输入他们在真实世界中使用磨损的先验知识，以便有效地与文件和文件夹交互。为了获得更逼真的磨损图像，我们还开发了几种模拟纸张风化的技术。

Although we may not be aware of it, wear is a real important source of information in our everyday life. Through wear, histories of our use of items are perceptually available to us in ways that inform and support the task we are doing. In this research, we developed a technique for visualizing the history of desktop objects using physical wear effect. While in the real world, documents and file folders usually getting smudged or torn out after being repeatedly used, the document and folder icons in an existing GUI system never change their appearance with the use of the corresponding digital objects. In the real office environment, wear is always an important source of information supporting the daily tasks of office workers. For examples, to find a frequently referred document, he/she may naturally lead his/her hand to pick up a relatively worn file folder first, as the frequent use of the folder tend to make it smudged and soiled. Also, to find a recently used document, a worker will not check the stack of documents covered with heavy dust, and to search for a recently created document he/she will skip those documents whose papers are already deteriorated. Therefore by making the file and folder icons change their appearance according to their history, the user is able to perceive and use the affordance of wear on the GUI and directly import their prior knowledge of using wear in the real world for effectively interacting with files and folders. To achieve more realist images of wear, we also developed several techniques for modeling the weathering of paper.
