In today’s era, real time data tagging is significant for research and development of new automotive technology. The ability to tag and classify data increases operational efficiency in terms of improvements of algorithms and enhancements of sensors used in current and future vehicle technology. Real Time Data Tagging Software (RT-DTS) application was developed to use in conjunction with the data acquisition system. In addition, this application will help the user to tag quickly and efficiently, identify data that are unique and significant enough to undergo extensive analyses to further enhance and improve algorithms and features that correlates to increased safety, which is the paramount goal across the automotive industry. The application currently runs in iOS and can be installed on Apple devices. This intuitive Data Tagging Software allows the driver to quickly swipe through or jump to pages showing icons of common scenarios and conditions for fast and efficient, real-time tagging of acquired data. This application operates in parallel with any data acquisition system and can be the time synchronized, via the time of arrival at PC, to efficiently retrieve tagged data from the massive database of acquired data. Furthermore, this application can be easily integrated to any data acquisition system, if required. The Data Tagging Software communicates wirelessly to the recording PC using TCP. This allows for convenient and efficient transmission of tagged data to the database. This paper will explain in detail the background objectives, approach, and features of the RT-DTS.
