Sound Feedback

Choose Setup > Project Settings > Sound Feedback.

Select one of the options for Sound Feedback:

• None – No sound feedback.
• After Each Key Press – A sound at each key press.
• After Each Input Element (default) – A sound after each element (Subject, Behavior, etc.) was entered.
• After Each Input Event – A sound after the event has been completely coded.

Sound Selection

If you selected to play sounds, select what to play under Sound Selection. Select Use Coding Scheme Sounds (for Elements Only) to play the sounds specified in the coding scheme (Subjects, Behaviors, or Modifiers). This option only applies when you have selected a sound feedback After Each Input Event.

Playback Control Options

Choose Setup > Project Settings > Playback Control Options.

Slider Range

Choose the segment of time you want to have displayed by the playback slider:

• All Streams – The segment between A and B represents the time between the start of the earliest event/external/media file and the end of the latest event/external/media file.
• Observation – The segment between A and B represents the time interval that data was scored in, no matter how long the other data/media file streams are.

Note: The selection above affects the behavior of the Jump to Begin or Jump to End buttons. For example, if the event log starts 60 seconds later than the first video frame, and you select Observation as Slider Range, clicking Jump to Begin will position the slider cursor to the start of the observation (at 60 seconds in the video), not at the start of the video. If you select All Streams, the same action positions the slider cursor to the start of the earliest of all streams, that is the start of the video.

Select Playback Control Buttons

By default some buttons are hidden in the Playback Control window. You can select or deselect buttons that you do not need while scoring. See The Playback Control Window for more information on the buttons and Playback Control Options for the buttons that can be hidden.

Loop Options

To replay a video fragment for accurate scoring or demonstration purposes:

• Loop Interval – By default the option User Defined is selected. With this option selected, you either loop the entire video or set an interval manually. If you select Fixed Interval, a loop of a fixed length is created. See The Playback Control Window.
• Interval Length – This option is enabled if you select Fixed Interval in the Loop Interval list. Set the length of the loop.

Quick Review

With the Quick Review function (see The Playback Control Window) you can automatically rewind to a certain point and play the media file at a certain speed. Customize your Quick Review function with the following options:

• Pause Playback After Quick Review – Select this checkbox if you want the video to pause after the video fragment is played back.
• Quick Review Interval – Enter the number of seconds you want the video to be rewound before reviewing.
• Quick Review Speed – Select the speed at which the media file is played back. Note that not all speeds are available with certain video formats.

Other Project Setup Options

Apart from the options described in Define Project Setup, the following options are available:

• Control External Devices or Programs During a Live Observation
• Specify the Duration of the Observation
• Enter Project Information
• Lock the Project Setup

Control External Devices or Programs During a Live Observation

You can control external devices or programs when you carry out a live observation with The Observer XT. For example, start a Data Acquisition System (DAQ) system or video recording with MediaRecorder when you start an observation. This ensures synchronization of data streams.

To Select External Devices

1. Choose Setup > Project Setup > Live Observation under Observation Source. The Devices window opens. If not, click the Devices button under Live Observation.

You have the following options:

• DAQ Settings (available with the External Data Module) – Select this option to co-acquire external (physiological) data during your observations. See External Data for details.
• Automatic Linking of Video Files – To associate videos that were recorded with, for example, an eye tracker, to an observation. Instruct the program how to locate the video files (see Automatic Linking of Digital Media Files). If you control MediaRecorder 4 or higher with The Observer XT, the videos are automatically linked to the observation, so do not select this option.
• Other Options – Depending on what devices or programs are connected, more options may be available, such as MediaRecorder, FaceReader, uASQ, or E-Prime. You can also create settings to control a program with command lines. See External Programs and the manual of those programs for details.

If you change the Observation method from live to offline between observations, you can no longer see the devices set for the live observations. To view them, right-click the observation in the Project Explorer, select Properties, and go to the Devices tab.
