Please watch this overview of the in-app training process, the key step in seeing success with Keen.
Keen works best if you train it with your hand in the same location and your body in the same position you want it to detect your gesture. Keen is designed to detect a repetitive motion at a localized site. During training, do your gesture - searching for the right hair, feeling around for skin imperfections, or biting your nails - for the full 15-20 seconds. Keen will record this gesture and look for it continuously after training.
Training is the most important step. When you train Keen for your gesture, it is looking for two things - the specific motion of your wrist, and the angle of your wrist with reference to the vertical pull of gravity. These two measurements create the "fingerprint" of your specific gesture. After training, Keen uses mathematical magic called Motion Fingerprint to detect your wrist movements and will vibrate when it senses a match to your fingerprint.
Start with one. Remember the Rule of One: Start with one hand, one trained gesture, for one week. We want you to get to know Keen, and yourself, before you add more gestures or a second Keen.
Button to fingers. Always wear Keen with the button pointing toward your fingers and on the same hand it was trained.
Get comfortable. Make sure your body is in the same position that you’re in when you normally make your gesture. This could be sitting tall, slouching at your desk, or lying in bed. Your body position affects Keen’s orientation relative to gravity. See the attached file to learn more.
Hand at the area. Have your hand already at your training area, ready to make your gesture, before you start training.
Move that wrist. Keen is looking for the specific motion your wrist makes during your gesture. If your gesture is mainly with your fingers, try to exaggerate your wrist motion a little bit during training. Keep doing the same small motion over and over during training. Watch yourself making your gesture in the mirror before you start training to see how your wrist is moving, and during training to ensure your wrist motion is constant.
Tweak those settings. Keen looks for the motion and position of your wrist and uses mathematical magic called Motion Fingerprint to detect the unique “fingerprint” of your specific gesture. After training, adjust the Detection Settings of your trained area to fine-tune Keen’s ability to detect your gesture.
Tighten “Motion Sensitivity” to reduce false alarms from similar gestures, like nail biting vs. eating. A tighter Motion setting will look very specifically for your trained gesture’s wrist motion. Widen Motion Sensitivity if Keen isn’t detecting enough true gestures. Keen will then look for both smaller and larger wrist motions similar to your trained gesture. Learn more.
Increase “Body Position Sensitivity” to improve detection when you’re in a different body position than your training, such as sitting up instead of leaning back. Your body position affects Keen’s orientation relative to gravity. A lower Body Position setting looks very specifically for your wrist to be at the same angle with gravity as it was during training. A higher Body Position setting will allow for both smaller and larger angles, and therefore different body positions from your trained position. Learn more.
Use the snooze. If Keen vibrates during similar gestures, such as eating or talking on the phone, try the "snooze" function. Press and hold the button for two vibrations to stop Keen from vibrating for the snooze duration time, set to an adjustable 7 minutes in the app. Bring Keen out of snooze by holding down the button for another two vibrations. Learn more.
Nickname your gestures. Train the same area for different body positions. One area could be “Forehead” with a nickname of “Desk” while another area could be “Forehead" with a nickname of “Bed.” Enable or disable an area as needed throughout the day, or to fine-tune training of a particular area. Learn more.
Move to two. Once you’re comfortable with Keen with one hand, one trained gesture, for one week, go ahead and add a second gesture or a second Keen. Disable previously trained gestures so you can focus on and fine-tune your new gesture until you’re comfortable with it.
