The Lucid Marketplace can automatically detect certain environmental characteristics of a respondent's session including the browser, browser version, device type, operating system and more. In order to access this information, these qualifications must be added to the Marketplace screener (while the Lucid Marketplace does detect this information in real-time, it is not provided by default).
Uses for device detection variables
There are four primary uses for the device detection variables.
1. Qualifying respondents
Add the device detection variables as qualifications to your survey, and then set the appropriate conditions to ensure that respondents match the desired profile.
The most frequently used are "MS_is_mobile" and "MS_is_tablet". Best practices for targeting with these qualifications is as follows:
Desktop/laptop users only: MS_is_mobile qualification, condition = false
Both cell phone and tablet users: MS_is_mobile qualification, condition = true
Cell phone users only (no tablets): MS_is_mobile qualification with condition = true and MS_is_tablet qualification with condition = false
Tablet users only: MS_is_tablet qualification, condition = true
Tablet and desktop/laptop users (no cell phones):
Add MS_is_mobile and MS_is_tablet qualifications, without setting conditions
Add a quota with 2 conditions: MS_is_mobile = true, MS_is_tablet = false
Set that quota to 0
2. Placing quotas on respondents
For example, you only want 25% desktop users on your study. You can include the MS_is_mobile detection qualification (without setting a condition), and set a quota for 25%.
3. Monitoring respondents
If device detection qualifications are added to the survey, you can download the respondent answer report to see device information for each respondent.
4. Sending device data to the client survey
Device detection variables can be appended to the Client Survey URL just as other qualifications can.
Dynamic nature of variable conditions
We keep our detection capabilities updated regularly. You can use the device qualifications below to screen for any of the associated conditions.
However, please be careful with setting specific conditions, as the conditions must meet an exact format. We recommend testing a survey (testing a study) carefully with qualifying devices when targeting with these qualifications.
