Stotts et al.developed a ‘hypervideo’ system that used video projectors to support distributed pair programming(distributed pair programming,专有词汇.指两人在不同地理位置利用协作工作完成同一编程任务）.With this system,each partner would work
in a specially equipped office that contained two video projection systems.One of the systems would project the shared screen image on the wall in front of the user.The second projection system displayed a real-time image of the remote partner on one of the side walls.When the partners wanted to discuss something,they would ‘look’ at each other by turning toward the image of their partner.
Stotts believed that this would allow for more natural interactions between the separated partners.Although some initial evaluation of the system was done,no empirical studies were completed.This work has been superseded by the dual
face-top system described next.
