INTRODUCTION This paper presents MyExperience, a system for capturing both Mobile computing has become an integral part of everyday life objective and subjective in situ data on mobile computing for many people, providing ubiquitous information access, activities. MyExperience combines the following two techniques: entertainment, and helping people stay connected to work, 1) passive logging of device usage, user context, and friends, and families. The most popular mobile device, the mobile environmental sensor readings, and 2) active context-triggered phone, has been adopted faster than any other technology in user experience sampling to collect in situ, subjective user human history [9]. In 20061, the number of mobile phone feedback. MyExperience currently runs on mobile phones and subscribers surpassed 2.5 billion and has more than twice the supports logging of more than 140 event types, including: 1) number of PC users worldwide. device usage such as communication, application usage, and Researchers are struggling to catch up. Tools and techniques media capture, 2) user context such as calendar appointments, and that have long been refined for studies of static computing 3) environmental sensing such as Bluetooth and GPS.
