手机的无位置特性的一个问题是，呼叫者很难预测接收者的状态，导致不适当的呼叫。一个很有前途的解决方案是通过向呼叫者提供有关接收者的上下文信息来帮助他们决定何时中断。我们测试了不同类型的上下文信息的有效性，通过测量的程度之间的协议接收者的愿望和呼叫者的决定。在模拟中，五组参与者扮演“呼叫者”的角色，在拨打电话或留言之间进行选择，第六组扮演“接收者”的角色，在接听电话或接收消息之间进行选择。呼叫者被提供了不同的上下文信息，如接收者的位置、他们的手机铃声状态、其他人的存在，或者根本没有信息。我们的研究结果表明，不同的语境信息产生不同的改进：更适当的中断或更好地避免不适当的中断。我们讨论的结果和实践中的其他重要的考虑因素，如隐私和技术的简单性。
A problem with the location-free nature of cell phones is that callers have difficulty predicting receivers' states, leading to inappropriate calls. One promising solution involves helping callers decide when to interrupt by providing them contextual information about receivers. We tested the effectiveness of different kinds of contextual information by measuring the degree of agreement between receivers' desires and callers' decisions. In a simulation, five groups of participants played the role of 'Callers', choosing between making calls or leaving messages, and a sixth group played the role of 'Receivers', choosing between receiving calls or receiving messages. Callers were provided different contextual information about Receivers' locations, their cell phones' ringer state, the presence of others, or no information at all. Callers provided with contextual information made significantly more accurate decisions than those without it. Our results suggest that different contextual information generates different kinds of improvements: more appropriate interruptions or better avoidance of inappropriate interruptions. We discuss the results and implications for practice in the light of other important considerations, such as privacy and technological simplicity.
