A brief description on how a LetsLearn! session works. When you begin a session initially there is a warm-up period. During this time the Engagement Video will not play even if the userís attention starts to fade. The user needs time to get interested in the study materials without interference from the system. Once the warm-up period expires the system is active and if the userís attention starts to fade the Engagement Video will play.
The Settings tab
NOTE: When you start LetsLearn! for the first time, all the sliders will be set to 0 and all the slider statuses will be OFF.
Below is a screenshot of a potential LetsLearn! Affectiv Trigger profile. In this example, LetsLearn! is configured to wait 120 seconds (2 minutes) before becoming active. Once active, the current slider settings indicate the Engagement video will play if the Short Term Excitement signal (Excite Short) falls under 45 OR if the Frustration signal goes over 80:
Setting the Warm-Up period duration
To change the warm-up period duration, enter a value into the text box labeled Seconds remaining.
Defining the Affectiv Trigger
To change the conditions that will trigger the Engagement video, use the sliders and slider status boxes. There is one slider/status box pair for each Affectiv signal: Engagement/Boredom, Short Term Excitement, Long Term Excitement, Frustation, and Meditation.
If a sliderís status is set to OFF, then that Affectiv signal will not trigger the Engagement Video. If set to under then the video will play if the Affectiv signal represented by the slider falls below the value the slider is set to. Conversly, if set to over the video will play if the signal is over the slider value. Set the slider values and statuses to match the conditions that you want to trigger the video.
TIP: Remember, the logical relationship between the sliders is an OR relationship. If the slider/status setting for any active slider is met, the video will play.
TIP: You can use the RESET button to quickly set all the sliders to 0 and their status to OFF.
