Media Objects
By clicking the first icon on the Objects side menu, a full list of Media Objects will appear. This is where you go to add media-based stimuli like images and videos, but also advanced features like audio recordings.
The following table gives an overview of the Media Objects available in Labvanced:
| Media Object | Description |
|---|---|
| Image Object | The image object can be used to show an image on a canvas frame. Via the image object, you can display image-based stimuli to your participants. Images are essential to the majority of experiments run in Labvanced, so understanding how they work is important. Read more. |
| Video Object | The video object can be used to present a video on a canvas frame. Using this object, you can present videos to your participants during your experiment. |
| Audio Object | The audio object can be used to present an audio file on a canvas frame. The audio object can play automatically based on your requirements or you can allow the participant to control when it is played. |
| Audio Recording Object | The audio recording object acts as a visual interface / handle for taking audio recordings of the participant during the experiment. The recording can be started and stopped via buttons or via custom events that you specify and can be uploaded to the secured Labvanced server or directly to your server. |
| Video Recording Object | This object can be used to record a video of the participant, a recording of their screen, or both at once. There are several options that can be enabled/disabled: showing the recorded video to the participant live or later in the experiment (or not at all), allowing the participant to control the start/stop/upload of the video, and determining where the video is stored as a variable. Using a video recording object also records audio from the participant. |
| Camera Snapshot Object | This object can be used to take a picture snapshot of the participant. To do this, video recordings must be enabled for the experiment. Options to show the camera button, snapshot button, and upload button can be hidden or shown to the participant. Events can be used to trigger the camera snapshot, or the participant can control it themselves. This tool is useful for verifying identity/demographic information of the participant, but should be treated as highly sensitive information. The snapshot is stored as a file variable. |
| I-Frame Object | The I-Frame Object can be used to display an I-Frame (embedded other website) inside the experiment. |
| Sub Study Object | This powerful object allows you to embed other Labvanced studies within a single ‘parent’ experiment. Read more. |
