These instructions are intended for older model bracelets ordered before Februrary 2019. For setting up bracelets shipped after February 2019, click here.
We know habits are hard to break but we'll get you set up in no time
- Charge your bracelet. To get maximum battery life and Bluetooth range, charge your bracelet overnight or for at least an hour.
Download the Slightly Robot app from the Google Play Store
- Open the top-left hamburger menu from the home screen, select Bracelet 1, and press Connect.
- Select a bracelet by serial number, then wait a few seconds. You will know the bracelet is connected when the graph starts to display lines. If you have two bracelets and don't know which bracelet is which, turn one bracelet upside down. If this is the connected bracelet, the graph will change.
Calibrating is the process of training your bracelet to recognize your specific behaviors. You should create at least one calibration for each orientation your hand could be in when performing your habit.
- Put your bracelet on. Remember to put your bracelet on the same hand each time you wear it, with the buckle pointing the same direction.
- Hold your hand in a position like the habit you want to track. If you pull your hair, place your hand as if you are pulling from the most common spot. If you bite your nails, put your finger near your mouth. If you pick your skin, touch a place that might be problematic. Hold your hand still because your bracelet responds to your hand's orientation, not your movement. Moving your hand while calibrating will confuse it.
- Press Add Calibration while holding this position. This records the position. Any time your hand stays in this position too long, your bracelet will vibrate. After the first vibration, each future vibration will be stored in your phone's records.
- Give your calibration a descriptive name. You can tweak the name and sensitivity of a calibration by tapping on the calibration
- Repeat steps 2 - 3 for each hand position you want to detect.
How It Works
Though it may seem like magic at first, the Slightly Robot Bracelet is actually a pretty simple device. You can think of the bracelet as a hand orientation sensor that is programmed to vibrate whenever your hand goes somewhere it shouldn’t, whether this is near your mouth, hair, or somewhere on your skin. Your phone connects to the device using wireless Bluetooth in order to set it up, control it, process the data, and display this data back to you.
The Slightly Robot Bracelet is based around a tiny device called an accelerometer. The accelerometer measures the bracelet’s orientation with respect to gravity, and by proxy, your hand’s position. As its name implies, the accelerometer also measures acceleration, but we don’t really use this data and run some fancy algorithms to keep it from affecting your bracelet’s accuracy too much. Though it may seem like it should intuitively, the bracelet does not detect movements or gestures themselves.
Unless you’re an octopus, your arm should only bend in a few places. This means that there are only so many different positions that your hand can be in. Therefore, by measuring the angle of your hand with respect to gravity, the accelerometer can determine where your hand is with a fairly high degree of precision, especially for positions near your head and face.
What the bracelet doesn’t know yet is which behaviors, and therefore which positions, you are trying to learn to avoid. To do this, you first pair the bracelet to your phone over Bluetooth using our app. Then, place your hand in the problematic position and press the Add Calibration button. This saves the bracelet orientation as a calibration. You can add as many of these as is necessary for your habit, like one for each finger or hair on your head! You can adjust the sensitivity of each calibration position individually. Broadening the calibration radius will have it trigger in a wider range of positions while narrowing it will do the opposite.
The bracelet will register an event only when all of the following conditions are met simultaneously
- The bracelet’s current orientation is within the sensitivity range of any calibration position.
- The bracelet has been in this position for more than the trigger time set in the settings menu.
- The bracelet is not asleep.
- The bracelet is connected to the phone.
Two things happen when the bracelet registers an event. First, the bracelet vibrates. The first vibration is a warning. For each vibration after the first, an event is logged in the phone. These events can be viewed according to time of day and day of week. You can delete events by tapping on them in the "Recent Logs" tab. That’s what the bracelet can do. The rest is up to you.
For Best Results
Things to remember
Now that you know the science behind your bracelet, here are a few things you should keep in mind in order to get the best results:
- The bracelet only works while paired with a phone, so you must keep it within range of the phone in order for it to work.
- The Slightly Robot app must be running on your phone, so if you turn your phone off and on again you may have to reopen the app.
- If you put your bracelet on your other hand, you will need to delete all of your previous calibrations and create new ones.
- Always wear your bracelet in the same orientation with the buckle facing the same direction.
- Fully charge your bracelet to maximize its Bluetooth range. An hour a day is usually sufficient but we think that you should get in the habit of charging it overnight.
- Sometimes you need more than one calibration position to cover a single position. Don’t be afraid to add and delete them as you find necessary.
- If the bracelet is alerting you too often at the wrong times, try deleting calibrations, narrowing your calibrations' sensitivity, increasing trigger time in the settings menus, or simply put the bracelet to sleep.
- To delete or rename a calibration, tap the name of the calibration.
You will see even better results from your bracelet by incorporating strategies used in traditional therapy. For example:
- Competing response training - When you feel the urge or the bracelet alerts you, do something else instead which is incompatible with the habit, like clenching your hands or locking your arms. Do the same thing every time until the competing response replaces the urge.
- Environmental management - Sometimes the environment can make the urge worse, like if there are few people around or nothing to do. Try going for a walk, doing some stretches, or moving to a different seat or room.
For more information on traditional therapy we especially encourage you to read the TLC Foundation's Expert Consensus Treatment Guidelines.
TroubleshootingSometimes getting your bracelet working just right can be tricky. If yours doesn’t connect properly or doesn’t vibrate at the right times, here’s some steps you can take to work out the issue.
If your bracelet does not connect or does not stay connected, follow these steps:
- Check that your bracelet is plugged in. The bracelet will work while charging.
- Check that your phone is running the Slightly Robot app. It's okay if the app is backgrounded. The bracelet will not function if your phone is not running the app.
- Check that the phone is within range of the bracelet.
- Don't connect a bracelet to more than one phone. If you do, disconnect from all old phones before connecting to a new phone.
- From the bracelet tab, wait one minute for the bracelet to connect. The Slightly Robot app will read "Connected" when the bracelet is connected.
- Toggle your phone's Bluetooth off and on again.
- Restart your phone.
If none of this works then it's Joseph's fault and he needs to know what's happening. Please email him at firstname.lastname@example.org.
If your bracelet doesn’t vibrate at all, take the following steps:
- Check that the bracelet is connected to the phone (see above). If two bracelets aren't working, test them one at a time.
- Make sure the turtle in the app homepage isn't sleeping. If it is, press Awaken.
- Set Trigger Time in the app's settings to 1 second.
- Take off the bracelet and set it on a table. Press Calibrate in the app. If the bracelet vibrates then the hardware is working properly. Delete this test calibration once you have confirmed that the hardware works. If the bracelet doesn't vibrate but it does log events on your home screen and calendar, then you have a broken vibrator. You can email email@example.com about replacements, repairs, and returns.
- Delete all of your calibrations.
- Put the bracelet on your wrist. Make sure the buckle is always pointed the same direction and the bracelet is always placed on the same wrist. If you change the wrist or the buckle direction you'll have to redo your calibrations.
- Place your hand touching your head as if you would pull your hair, bite your nails, or engage in another habit. It's a good idea to start with your head because hand positions near your head are easiest for the bracelet to understand. Technically speaking, the bracelet responds to the orientation of your wrist, rather than the position, but this distinction matters least for hand wrist positions near your head. See How It Works above for more details.
- With your hand touching your head as if you would pull your hair, bite your nails, etc., press Add Calibration. Leaving your hand where it is bracelet should vibrate. Putting your hand down it should stop. You now have one functional calibration.
If your bracelet is behaving erratically, either the bracelet vibrates when it's not supposed to or the bracelet doesn't vibrate when it is supposed to. Finding the proper balance is about trying new things and figuring out what works for you. Here are several settings you can adjust to get more personalized results.
- Trigger Time – This controls how long you must hold an orientation before the bracelet will vibrate. Increasing the trigger time will increase how long you must hold an orientation before the bracelet vibrates and vice versa. If the bracelet isn't vibrating enough, decrease trigger time to 1 second. If the bracelet is vibrating too much, increase trigger time to 4 or more seconds.
- Sensitivity – This controls how similar a wrist orientation must be for the app to match it to a calibration. "Narrow" calibrations only match wrist orientations very close to the calibrated one. "Broad" calibrations match wrist orientations further away from the calibrated position.
- Number of Calibrations - The more calibrations you have, the more different positions the bracelet will vibrate. If the bracelet is vibrating too much, try deleting your calibrations and making fewer of them. If the bracelet isn't vibrating enough, try adding a calibration wherever it is failing to go off.
