Data Collection and Studies

What is a study?

A study is a part of the data collection tool (DCT), which is a tool for the automated collection of standardized selfies, toenail images, and hand images. The DCT was created for specialists to collect and analyze participants’ image data during consumer studies, decentralized trials, and real-world evidence studies. For more information on how to conduct a study, check out our tutorial here (link to be added).

How many different surveys can I have per study?

You can configure the study and select the desired number of stages. You can have one or two stages per day. Every stage can have a survey before and/or after each stage. These surveys are now the same for every stage.

How does the data from studies get exported?

You can export data about the study progress via our B2B portal in CSV format. The platform also provides the functionality to export single images via the B2B portal. For bulk upload, we transfer the data to your cloud or provide credentials for Azure blobs to export it.

Are survey statistics calculated automatically?

We don't get analytics for surveys at this point, but we're planning to implement it in the future. Right now, you can get a CSV file with questions/answers for every participant.

Where can I get all the reports and analyses for my study?

To access reports on a study, go to the “Datasets” tab and find a dataset attached to your study. You can get the reports on it just like on any other dataset. Learn how to get a report on your dataset here.

How quickly can a study be set up on the platform?

From our experience, if you have the study design on hand, you can do it within 15-30 mins.

Can the company account be accessed by multiple admins/users?

Yes. It’s possible to provide access to the company account to multiple B2B users.

How many studies can be run at one time on Haut.AI?

We do not have limitations on the number of studies that can be run at the same time.

What is LIQA?

LIQA stands for Live Image Quality Assurance. It is an instrument that helps users to take standardized images by indicating the correct head position and lighting intensity. According to a study utilizing LIQA module supervision, 87% of images had sufficient quality for further analysis if LIQA was used, while only 32% of images had sufficient quality when data-quality improvement measures included only written and schematic instructions for participants. Read more about LIQA on our blog here. Here’s an example of how LIQA works:

What’s the difference between LIQA e-commerce and LIQA lab?

The main difference is the level of standardization of the images collected with different versions of LIQA.

LIQA e-commerce

LIQA lab

Face detection (presence of face in frame)



Face tracking (face shape and position tracking)



Tracking of camera-to-face distance



Tracking of head rotation angles



Tracking of image resolution



Analysis of face illumination



Configurable formats of collected images



Maximum size (in pixels) of collected images

2000 x 2000

No limit

If I want to use LIQA in my study, do I have to pay an additional fee?

Not if the study is conducted through our platform. If you want to integrate LIQA into your services, a separate fee has to be paid. You can check out the pricing information here.

Does LIQA require any backend?

No. All calculations are performed on the front end using the mobile device’s capacities. No server connection is required after LIQA initialization, no image or data is sent, and there are no time delays.
