WebTEM: A Web Application to Record Text Entry Metrics
WebTEM is a Web application to record/gather text entry metrics. It works with almost all operating systems, browsers, and text entry techniques. Yet to verify compatibility, press the Check button and type a chunk of text to confirm that it detects all insertions and deletions. Press the Back button to return to the settings. To use the application, first enter a valid email address, study-specific information, and keyboard type. The application emails all logs to the email address provided and then deletes all data from the server. The study-specific settings are used for recordkeeping. Then select a phrase set, number of phrases in the session, performance metrics, and optional features. The most popular performance metrics and features are preselected for your convenience. Arif & Stuerzlinger, 2009 reviews and analyzes the most popular text entry metrics. International Metrics for non-Latin scripts are displayed when a non-Latin corpus is selected and calculated using the output stream convention proposed by Sarcar et al., 2015. The application displays the phrases in a randomized order. Press the Start button when ready to start the study. Make sure that the device has access to the Internet throughout the study.
The application generates one information (.INFO) and two tab-delimited files (.TSV) to record all settings, timestamped events, and performance metrics, respectively. Each row of the metrics log represents a phrase and each column a metric. The last row holds average values. Events are recorded as [time,text,event,duration,insertion,deletion], where time is the number of milliseconds since January 1, 1970, text is the current state of the transcribed text, event is a user or system action (tap, autocorrection, etc.), duration is the time for the action in milliseconds, and insertion and deletion are character(s) entered and deleted by the action, respectively.
