AOMS TOT jr Tutorials

First, you may want to read the AOMS TOT jr introductory and information page over here if you have not done so.

Like many other high tech products, AOMS TOT jr presents some level of complexity. The complexity comes from several elements. If we can separate these elements, we can treat the complexity one element at a time. So, let’s get started.

Tutorial #1: Basic Training of AOMS TOT jr

Setup: Use the AOMS TOT jr app installed in your iPhone XR to scan your hands or face. With this tutorial, you do not need to use the mirror and the belt attachment as mentioned in the introductory page.

Purpose: With minimum setup, this tutorial is designed for the user to get familiar with the app’s basic functions. The tutorial lets the user test how far the object should be put away from the iPhone and what actions need to be taken to make scans, including how to use voice commands and how to email out a single file or a pair of files. Note that timing is important in starting, resetting, and finishing the scans and this tutorial is designed to tell you all of these.

• Install the AOMS TOT jr app on your iPhone XR.

• Go to the AOMS TOT jr settings and input the email address etc. for the app.

• Launch the app and make sure the front camera is working. It can be verified by seeing live video on the iPhone screen.

• Now, let’s follow a designed training scheme with your two hands and let’s scan your left hand first. You can practice with your face too. In fact, scanning face is easier, since the object is larger than hand. But let’s do it the hard way.

• Tap the ‘Start’ button and enter the necessary information, such as patient last name, first name, left or right foot, as you did in the AOMS TOT app.

• When ‘L’ becomes orange, it is ready for the scan. The app is waiting for your command. There is a ‘time out’ period and it is about 30 seconds, so get ready in 30 seconds. What happens if the ‘time out’ period is reached? The voice command will no longer be available. If that happens, you can tap ‘Start’ again to re-activate the voice.

• Hold the iPhone with your right hand and put your left hand roughly 12 inch away from your right hand which holds the iPhone. You do this with your two hands and the iPhone in front of you. You should be able to see your left hand through the live video.

• Now you can say words like “Go”, or “Scanner”, or “Start”, or combination of them, like “Scanner Go” to activate the scanner. The screen of the live video will change to a 3D image of the scanned object on a black screen and the 3D image is ever updating based on the location and orientation of the iPhone.

• If the 3D image does not look alright, for example there are holes on the image; you move your right hand with the iPhone a little closer or a little far away from your left hand, depending on the distance, and say “Reset” or “Redo” or “Retry” or combination of them. The feedback you get from your practice will tell you whether to move closer or farther away. After reset, the scanning process will show you a new image. You can do this repeatedly, until you see the full image of your left hand.

• Move your iPhone around the left hand a little (for now). We will practice it more in future tutorials.

• Note that the initial distance is important and the scan may fail completely. If the initial distance to the left hand is way too far or way too close, the scan will fail with an error message. At that time, you can redo the scan by tapping ‘Redo’ button.

• When you want to terminate the scanning, you say “Stop”, or “Enough”, or “Finish”, or “Exit”, or “Quit”, or combination of them, the scanning will stop. If you do not terminate it by voice, the scanning will continue until the maximum number of frames is reach. This number can be set in the app settings.

• At this time, you can choose ‘Redo’ or ‘Save’ by tapping any of these buttons, depending on the image you see on screen. If you choose ‘Redo’, you will redo the above procedure. If you choose ‘Save’, the ‘L’ circle become green. It means the image is ready.

• At this stage, you can email this single image if you want to. Or, you can wait until the right hand image is ready as well.

• Now, let us try to send the single image first. So tap the green ‘L’ button and the app will ask you whether you want to send a single image alone or wait for the other image. Choose ‘Yes’ to send a single.

• At this time, the email interface comes out. Check everything. Tap ‘Send’ and you should receive an email. So check your email Inbox. At this stage, you are not able to open the 3D image yet. Later, once the lab gets the upgrade for the AOMS TOT conversion/processing program, they should be able to see the 3D image in their program.

• If you want to scan two hands and send the two images at the same time, you can choose ‘Start’ again after the left hand has been scanned. Repeat the same process as you did with your left hand and go ahead to scan your right hand.

• After both hands are scanned, verified by the two green circles, you can send both images at the same time by tapping either ‘L’ of ‘R’.

Tutorial #2: Wearable mode of AOMS TOT jr

Setup: Use the waist belt attachment mentioned in the introductory page, besides the AOMS TOT jr app installed in your iPhone XR to scan patient’s foot.

Purpose: With the belt attachment setup, this tutorial is designed for the user to take scans with two hands handling the foot, while using voice commands to control the scanning process, and do some waist maneuvering aiming at the plantar surface of the foot. In this mode, ‘neutral position’ scanning is made possible.

Notes on Tutorial #2:
What you have learnt in Tutorial #1 can be applied to this tutorial. It is a little hard to describe how to use waist to control the scanning angles though. For this innovative wearable scanning mode, we could not think of any comparables. It requires you keep your arms stable, while maneuvering your waist to do some ‘hokey pokey’ to let the iPhone scan around the plantar surface of the foot. Make some trials and let us know your ideas.

Tutorial #3: Hand-held mode of AOMS TOT jr – supine position

Setup: Use the mirror attachment mentioned in the introductory page, besides the AOMS TOT jr app installed in your iPhone XR to scan patient’s foot in supine position.

Purpose: With the mirror attachment setup, this tutorial is designed for the user to take scans with your two hands operating on the iPhone, while using voice commands to control the scanning process. In this supine-position mode, patient leg needs to be supported by a stand, or the patient needs to lie down on doctor’s high bed or chair.

Notes on Tutorial #3:
What you have learnt in Tutorial #1 can be used in this tutorial.

Tutorial #4: Hand-held mode of AOMS TOT jr – prone position

Setup: Use the mirror attachment mentioned in the introductory page, besides the AOMS TOT jr app installed in your iPhone XR to scan patient’s foot in prone position.

Purpose: With the mirror attachment setup, this tutorial is designed for the user to take scans with your two hands operating on the iPhone, while using voice commands to control the scanning process. In this prone-position mode, patient leg needs to knee down on a chair.

Notes on Tutorial #4:
What you have learnt in Tutorial #1 can be used in this tutorial.

Special notes:

• You do not have to use voice. If for any reason, you do not want to use voice, you can use the buttons shown on screen. After you have tapped ‘Start’, you can tap ‘Scan’ to activate the scanning. In this case, you cannot stop the scanning by voice, and you have to wait until the maximum number of frames is reached. The number can be set in the settings.

• After you have scanned both feet, you cannot send one at a time. If you send one, the other one will be lost. If you really want to scan one and send one, you have to do it with ‘scan one and send one’ separately.

• The scanning process is flexible. Let’s assume you have done both feet, but for any reason, you want to redo the left foot. You can tap the ‘Start’ button and make sure you choose ‘Same Order’. Then choose left foot.

• After one or both feet have been scanned, if you ever want to redo the order from fresh, you can tap the ‘Start’ button and make sure you choose ‘New Order’.

• An important thing you might not have realized. When you use the mirror attachment, the image will be flipped, i.e. left becomes right and right becomes left. The app relies on your input to make correct judgment. So when you are prompted to enter either ‘L’ or ‘R’, please double check whether left foot or right foot is being scanned.

• “Practice will make you perfect”, so keep practicing until you feel good enough.
