Supporting Your Users During a BodyScan
There are 3 events that will lead to an interrupted scan:
- User places their phone too high
- User places their phone too low
- Computer vision cannot see all of the user's joints for an extended period of time
If these events occur, BodyScan V22.0 will:
- Instruct the user to either place their phone on a higher or lower surface
- Give the user information information about what may have gone wrong and how to correct these issues to run the scan properly
As intuitive as Advanced Health Intelligence's scans are, there are still some requirements for your users in order to get accurate, repeatable, and error-free scans. We recommend incorporating a Scan Guide to educate your users on how to take a scan so they have an error-free experience and get great results.
Essential Points | Why? | What could happen if not followed? |
|---|---|---|
Wear tight-fitting clothing, or as little as possible (underwear, tights, etc). | We measure everything captured within the outline, including clothing. | The measurements will not be true to the user's body. Baggy clothing causes increased measurements, including body circumference, composition, health indicators, and risks. |
The device must be placed with the front camera at hips height of the user. | The user needs to fit their entire body within the outline. | The user won't be able to fit into the outline correctly. This results in a failed scan. |
The device should be propped up against a solid object | The capture is designed to be completed solo, therefore the device needs to be propped up against a solid object. | The device could fall or become misaligned during the scan, increasing the failure rate. |
Find an area that’s well-lit without direct sunlight falling across their body | Our image inspection needs to find key points of the body in order to successfully process the images. Poorly lit or areas much brighter than others can confuse our image inspection. | The image inspection could fail to pick up parts of the body required for a successful scan. |
They should have 13ft/4m of clear space. | The user will generally need to be at a distance of 2m from their device to fit in the device. They also need to make an A pose. | The user won't be able to fit into the outline correctly. This results in a failed scan. |
We also recommend making the following points:
- The background should be as clutter-free and plain as possible. Avoid backgrounds that contain bright windows, intense contrasting between floors & walls.
- For the side image capture:
- They need to continue to look at the device, but avoid twisting their shoulders.
- They should keep their feet together.
In the Technology Demo App, we use a series of static images explaining how to take a great scan, however, we recommend that partner's create a guide using a style familiar with their users. For example, a video or animation might better suit the demographic (language, geographic location, age group) and overall mood (fun and energetic or sober and serious).
Unique to V22.0, interactive guides will assist the user to achieve a successful scan; V22.0 will alert the user of positional errors as follows:
The cues can be specific to alert for particular positional markers and actual phone orientation:
Our detection software is specific enough to warrant errors when another person is detected in the frame:
