Convivo是一个VoIP系统，旨在为质量较差的网络提供可靠的语音通信，特别是在发展中国家的农村地区。Convivo引入了一种在网络性能不佳的情况下保持语音通信交互的原始方法：界面自适应机制，该机制可调整用户界面以减少高延迟和低带宽网络的影响。接口模式有利于高延迟连接的轮流，即使在极低带宽或高错误率的情况下也有助于维持语音通信。在多米尼加共和国的一个农村社区对该系统进行了评估，发现界面适应有助于用户在网络性能下降时保持语音通信交互。从全双工到语音信息的转换特别有价值。最初的结果表明，随着用户对应用程序的体验越来越多，他们希望基于feed手动控制转换…
Convivo is a VoIP system designed to provide reliable voice communication for poor quality networks, especially those found in rural areas of the developing world. Convivo introduces an original approach to maintain voice communication interaction in the presence of poor network performance: an Interface‐ Adaptation mechanism that adjusts the user interface to reduce the impact of high latency and low bandwidth networks. Interface modes facilitate turn taking for high latency connections, and help to sustain voice communication even with extremely low bandwidth or high error rates. An evaluation of the system, conducted in a rural community in the Dominican Republic, found that Interface‐Adaptation helped users to maintain voice communication interaction as network performance degrades. Transitions from full duplex to voice messaging were found particularly valuable. Initial results suggest that as users get more experience with the application they would like to manually control transitions based on feed...
