SHF: Small: Leveraging User Preferences for Mobile User Experience Improvement

移动用户对获得优秀的用户体验有着苛刻的要求，这是当今移动设备设计师和制造商面临的最大挑战。从计算机系统的角度来看，电池寿命（即能量）和服务质量（QoS）（即性能）是影响用户体验的两个主要因素。有效地平衡这两个因素对于实现高水平的手机用户体验至关重要。已经有研究在各种计算平台上实现能量和性能之间的最佳权衡，但它们不适应新兴的以用户为中心的移动平台。不同的用户对相同能量和性能的设备有着不同的感知，即使是同一用户在不同的环境下对相同能量和性能的感知也是不同的。个人用户？用户的偏好通常被认为是决定用户对设备QoS和电池寿命满意度的最重要因素。由于心理的影响，不同的用户有不同的偏好。此外，周围环境也会显著改变用户的偏好。准确地描述不同用户在不同情况下的偏好是至关重要的，并利用它们来指导电池寿命和QoS权衡，以增强用户体验。该项目将促进移动设备满足日益增长的对优秀用户体验的需求，并将更多有用的应用程序投放到移动设备中，使正常的生活和工作变得更加方便和高效。该项目还将通过参与代表性不足的群体，并与当地工业和德克萨斯医疗中心合作，为社会做出贡献。研究者正在探索一个创新的研究项目，根据个性、情感、人口统计特征来描述用户偏好的多样性，并在移动平台上执行偏好引导的能源性能权衡，以有效地改善移动用户体验。该项目从用户的角度重新思考移动平台的设计，将为下一代移动平台打开一扇大门，下一代移动平台可以智能、自动、无意识地定制配置，以满足每个用户在不同情况下的需求。

Mobile users always have demanding requirements on gaining an excellent user experience which is the top challenge faced by todays mobile device designers and producers. From computer system perspective, the battery life (i.e., energy) and quality-of-service (QoS) (i.e., performance) are the two major factors to the user experience. Effectively balancing these two factors is essential to enable a high mobile user experience. There have been studies on achieving the optimal trade-offs between energy and performance for various computing platforms, but they are not adaptable to the emerging mobile platforms which are much more user-centric. Various users have diverse perceptions on the device with the same energy and performance, and even the same user perceives the same energy and performance differently at different circumstances. The individual user?s preferences are generally considered as the paramount factor that determines the user satisfaction with the device QoS and battery life. Different users possess different preferences due to the impact of psychology. Moreover, the surrounding circumstances also significantly change the user's preferences. It is crucial to accurately characterize the preferences of different users at different circumstances, and leverage them to guide the battery life and QoS trade-offs for the user experience enhancement. The project will facilitate the mobile devices to meet the increasing demands on the excellent user experience, and enforce the desire of launching more useful applications into the mobile devices, making the normal living and working more convenient and efficient. This project will also contribute to society through engaging under-represented groups, and collaborating with local industries and Texas Medical Center.The investigator is exploring an innovative research program to characterize the diversity of user preferences depending on personality, emotion, demographics, and perform the preferences-guided energy-performance trade-off in mobile platforms to effectively improve the mobile user experience. This project, which rethinks the mobile platform design from the user perspective, will open the door for next generation mobile platforms that can intelligently, automatically, and human-imperceptibly customize their configurations to satisfy each single user at different circumstances.
