Keen Vibrates Too Much or Not Enough
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.
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.
Keen Vibrates Away from Trained Area
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. Keen does not know where your head is, where your arms are, or where the ground is. If Keen vibrates at a different location away from your trained area, your wrist is likely in the same angle with gravity as it was at the point of your trained gesture, and your wrist is making a similar motion as it did when you trained Keen.
When this happens, please try the following:
1. Delete the trained gesture and retrain it using a slightly bigger wrist motion during training so that when your wrist is in these other locations Keen won't sense a match.
2. When Keen vibrates in these other locations, open your app and slightly decrease the Body Position Sensitivity setting until the vibration stops. Then make sure Keen still catches your true gesture at the new settings. You may need to repeat this exercise a few times until you reach a satisfactory setting. We likely won't be able to eliminate all false detection, but most people should be able to achieve an optimal balance. Remember, even false detection helps you develop awareness of your hand position.
3. You might also consider using the snooze feature if it's appropriate. Hold the button down for two vibrations (approximately 3 seconds), and it will stop vibrating for the snooze duration time, set to 7 minutes in the app. The "snooze duration" is the period of time for which it will go to sleep. You can bring it out of sleep by holding down the button for two vibrations again at any time when it is asleep, and you can adjust the snooze length in the app.
Keen Seems to Vibrate Continuously
If your Keen seems to vibrate continuously, this typically indicates that your Motion Sensitivity and Body Position Sensitivity are set far too high. Open the trained area in the Keen app, and if your settings are on the high end of the ranges, lower them. This should ease the amount of vibrations you are experiencing. Remember that a low Motion Sensitivity number will have your Keen looking very specifically for the motion your wrist made during training, while a high number will have your Keen looking for a much wider range of wrist motion. Similarly, a low Body Position Sensitivity number will have your Keen looking very specifically for the angle your Keen/wrist made with the vertical pull of gravity during training, while a high number will have your Keen looking for a much wider range of Keen/wrist positions.
Keen Does Not Vibrate
After being fully charged, you should feel a vibration when you press Keen's button. If you do not feel a vibration when pressing Keen's button, please open a support ticket.
