PIT PROTEIN INTERACTION THEATER

PIT已经从仅仅是一个大屏幕双 头部跟踪立体显示到一个几乎准备黄金时间两个 用户在本报告所述期间的工作环境。 的移植 CORWIN应用到PIT，通过进入研究生完成工作 Tim普雷斯顿验证了 一个应用程序，并帮助我们开发了一个框架， 选择应用程序的参数。 研究生凯文亚瑟 完善和改进了控制PIT的软件库 并提供应用程序和PIT之间的接口。 的 库正在被我们实验室内的其他人拾取和使用， 这个项目之外的应用。 这为用户提供了宝贵的 关于文件功能和质量的反馈， 为我们在下一次报告中公开软件做准备 期 本报告所述期间取得的具体改进 包括：-在PIT膝上型电脑上启用应用程序控制面板 计算机-用于在笔记本电脑上显示的PIT控制面板 在Tcl/Tk中实现-指向和3D拾取功能， 已实施-仪表盘、拨号盘、6自由度手持指示设备和 将PHANToM集成到系统中-磁跟踪器（2个头 和2手）的速度和鲁棒性，通过集成新的 跟踪和控制软件（在另一个通用项目中开发 在实验室中使用）-系统稳健性得到提高-初始工作 做了关于解耦显示和仿真程序的改进 响应于用户输入，特别是头部运动。

The PIT has advanced from being just a large-screen dual head-tracked stereo display to an almost -ready-for-prime-time two user work environment during this reporting period. Porting the CORWIN application to the PIT, work done by entering graduate student Tim Preston, validated the ease of porting for the visual aspects of an application and helped us to develop a framework for returning user picking parameters to the application. Graduate student Kevin Arthur has refined and improved the software library that controls the PIT and provides the interface between applications and the PIT. The library is being picked up and used by others within our laboratory in applications outside this project. This provides valuable user feedback on both functionality and quality of the documentation in preparation of our making the software public in the next reporting period. Specific improvements made during this reporting period include: - Application control panels are enabled on PIT laptop computers - PIT control panels for display on the laptops were implemented in Tcl/Tk - Pointing and 3D picking functions were implemented - Buttons, dials, 6 DOF handheld pointing devices and a PHANToM were integrated into the system - Magnetic tracker (2 heads and 2 hands) speed and robustness were improved via integration of new tracking and control SW (developed in another project for universal use in the lab) - System robustness was improved - Initial work was done on decoupling display and simulation processes for improved responsiveness to user inputs, particularly head motion.
