The Short Track Speed Skating recording officials are divided into seven positions, the main recording work positions are chief referee and competitor steward. There are seven positions involved in the recording, with the main positions being the chief referee and competitor steward. The other positions assist in the recording process. The chief referee and competitor steward have the greatest involvement in the recording procedure before, during, and after the competition.

These two main positions lead the communication between other recorders for the

competition and complete the overall recording process. In particular, the competitor steward is an important position as it creates most of the records of the competition. During the competition, the assistant referee only participates in a simple record for communication with the chief referee after each race. The photo finish line judge makes a record sheet of the time and order of the finishers after each race on the competition. The organizer acts as a

messenger for posting information, with the exception of the announcement procedure before the competition. Coaches or skaters are primarily responsible for receiving records and viewing information, with the exception of the procedures of the application and commentary before the competition. The technical committee receives only the results after the

competition.

The trend of the App development is based on User experience and User Interface.

UX must include useful functions that take into account the user experience and habits, and the user should be able to accept and adapt at the time of upgrade of the App. In terms of the UI, it is effective to consider functions that the user thinks as friendly and easy to manipulate on the screen.

Before the competition, the App functions are focused on User Experience.

According to ISU rules, the main tasks of recorders before the competition are the

announcements, application and transmitting the information of the applicants, making the seeding list, posting the seeding list, commenting on the seeding, creating and posting the make-up of the races.

User experience. The App should include the functions reflected user experience and habits; instant message, bulletin board, mailing, push notification, office, memo, ringtone, calendar, and calculator. These functions can help recording officials to perform their duties listed above. In particular, the office and bulletin board functions have the highest demand rates before the competition.

User interface. In terms of user interface, the App should be user friendly and suitable for reasonable usage. The digitalized form, page optimization, sharing, and video playing App functions can help recording officials to easily access this App for viewing and sharing posted information before the competition. In particular, the digitalized form and page optimization functions have the highest demand rates before the competition.

During the competition, the App functions focus on both User Experience and user interface. According to ISU rules, the main tasks of the recorders during the competition are communication of the penalties and disqualifications, video replaying, transmitting the information of the time and order of the finishers, making the results of each race, creating the make-up of the races, posting the make-up of the races, and posting the results of the each rounds.

User experience. The App should include the functions reflected in user experience and habits; instant message, bulletin board, mailing, push notification, office, memo, ringtone, and calculator. These functions can help recording officials to perform the duties listed above.

In particular, the office function has the highest demand rate during the competition.

User interface. In terms of user interface, the App should be user friendly and suitable for reasonable usage. In particular, the digitalized form, page optimization, sharing, and video playing App functions can help recording officials to easily access this App in order to view information and play videos via smart devices during the competition. Here, the sharing function has the highest demand rate during the competition.

After the competition, the App functions are focused on both User Experience and User interface. According to ISU rules, the main tasks of recorders after the competition are making the final result, posting the final result, and reporting the final result.

User experience. The App should include the functions reflected in user experience and habits; instant message, bulletin board, mailing, push notification, office, memo, ringtone, and calculator. These functions can help recording officials to perform their listed above. The office function has the highest demand rate after the competition.

User interface. In terms of user interface, the App should be user friendly and suitable for reasonable usage. The digitalized form, page optimization, sharing, and video playing App functions can help recording officials to easily access this App in order to view and share the final results after the competition. The digitalized form is showing the highest demand rate after the competition.

The research participants firstly choose the App functions what they think it is necessary for the each recording procedure, therefore there are no App functions which were evaluated as Indifferent and Reverse qualities.
