集成皮科投影仪的移动的电话的第一个工作原型已经被展示，预计这种投影仪电话将在未来三年内销售。需要与大量信息交互的应用程序将受益于大投影及其高分辨率。本文分析了集成投影仪与地图交互时的优点和缺点，并讨论了有益于投影仪手机移动的应用程序开发的发现。我们特别报告的应用程序，使用的移动的手机的屏幕，投影或两者的组合的实现。这三个选项在用户研究中进行了比较，其中参与者必须使用每个选项执行三个不同的任务。结果为使用内置投影仪的积极方面提供了明确的证据，但也显示了与文本输入相关的一些消极方面。
First working prototypes of mobile phones with integrated pico projectors have already been demonstrated and it is expected that such projector phones will be sold within the next three years. Applications that require interaction with large amounts of information will benefit from the large projection and its high resolution. This paper analyses the advantages and disadvantages of an integrated projector when interacting with maps, and discusses findings useful for the development of mobile applications for projector phones. We report in particular the implementation of an application that uses either the screen of the mobile phone, the projection or a combination of both. These three options were compared in a user study in which the participants had to perform three different tasks with each option. The results provide clear evidence for the positive aspects of using a built-in projector, but also show some negative aspects related to text input.
