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

移动的用户总是对获得优秀的用户体验有苛刻的要求，这是当今移动终端设计者和生产者面临的最大挑战。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移动的用户体验至关重要。已经有关于实现各种计算平台的能量和性能之间的最佳权衡的研究，但是它们不适用于新兴的更加以用户为中心的移动的平台。不同的用户对具有相同能量和性能的设备具有不同的感知，甚至同一用户在不同情况下对相同能量和性能的感知也不同。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。不同的用户由于心理的影响，会有不同的偏好。此外，周围的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环境下的偏好，并利用它们来指导电池寿命和QoS权衡以增强用户体验至关重要。该项目将促进移动的设备满足日益增长的用户体验需求，并加强在移动的设备上推出更多有用的应用程序的愿望，使正常的生活和工作更加方便和高效。该项目还将通过参与弱势群体，并与当地行业和德克萨斯州医疗中心合作，为社会做出贡献。研究者正在探索一种创新的研究计划，以表征用户偏好的多样性，这取决于个性，情感，人口统计，并在移动的平台上执行偏好引导的能量性能权衡，以有效地改善移动的用户体验。该项目从用户的角度重新思考了移动的平台设计，将为下一代移动的平台打开大门，这些平台可以智能地、自动地和人类不知不觉地定制其配置，以满足不同情况下的每个用户。

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.
