English to Chinese Tech/Engineering IT (Information Technology) phone

With Affdex, processing takes place on the device, not on a remote server, as is the case with some comparable technologies, according to Affectiva. That raises the possibility of developing systems that sense emotions in real time and feed their results into another app and thereby change what happens with that app. For example, constant emotional feedback could change {the trajectory of a game or an interactive story} depending on how the user feels about various scenes.

据Affectiva声称，就Affdex而言，处理这一块在设备端进行，而不是在远程服务器端进行，一些同类技术也是如此。这提高了开发出这种系统的可能性：能够实时感知情绪，并将感知结果馈送到另一个应用程序，因而借助该应用程序改变发生的情况。比如说，不断的情绪反馈有望改变{游戏或互动故事的轨迹}，这取决于用户对各个场景有怎样的感受。

何谓：游戏或互动故事的轨迹？
还是说trajectory仅仅与a game搭配，而不是还与an interactive story搭配？
