Abstract

In order to increase the ways that users can intuitively interact with a tabletop display, we developed UlteriorScape. This system integrates two major functions of its predecessors. As with Tablescape Plus, UlteriorScape uses tabletop objects as both projection screens and input interfaces. As with the Lumisight Table, the tabletop is physically single, but visually multiple with a view-dependent display, which can show different images to each user around the table. We developed several applications that demonstrate the advantages of UlteriorScape. In one, a single user can hold a simple screen-object over the tabletop and see additional images projected onto its surface. Those images change interactively based on the position of the object, which is tracked by ID. In another application, multiple users can simultaneously work with a single mountain-shaped object that displays separate images on each side. In this paper, we describe the system design of UlteriorScape and its applications.

UlteriorScape:基于视图的桌面显示器上的交互式光学叠加
为了增加用户可以直观地与桌面显示器交互的方式,我们开发了UlteriorScape。本系统集成了前人的两大功能。与tableescape Plus一样,UlteriorScape使用桌面对象作为投影屏幕和输入接口。与Lumisight Table一样,桌面在物理上是单一的,但在视觉上是多个的,具有与视图相关的显示,可以向桌子周围的每个用户显示不同的图像。我们开发了几个应用程序来展示UlteriorScape的优势。在一种情况下,单个用户可以将一个简单的屏幕对象举过桌面,并看到投射到其表面的其他图像。这些图像会根据对象的位置交互变化,对象的位置由ID跟踪。在另一个应用程序中,多个用户可以同时处理一个山形物体,该物体在每一侧显示单独的图像。本文介绍了UlteriorScape的系统设计及其应用。
