1. Before you buy

It is a measuring device for forces and impacts acting on a head while doing sports. The system consist of: a sensor, mobile application and cloud service.

ACT Head Impact Tracker has three parts: head sensor, smartphone mobile App, and Cloud service. When  head sensor detects an event on a head with 10g or more, it sends information to a Cloud server via ACT Head Impact Tracker smartphone mobile App. The Cloud server processes the information, saves it, and sends the event data back to the assigned User Accounts where it can be accessed via mobile Apps or Browser Access in www.act-tracker.com. If the data transfers are available, this should take no more than few seconds.

All the athletes in sports where frequent impacts or forces act on a head occur.

MOBILE DEVICES’ FUNCTIONALITY WITH ACT HEAD IMPACT TRACKER

Currently ACT Head Impact Tracker mobile App is only available for Android 10 and newer Android operating systems.

Test if your mobile device works with passive or active scanning.

1. Give ACT App permissions to use “Location”, “Specific location” and “Nearby devices” when applicable.

2. Turn on Bluetooth® wireless connection and activate connection to Wi-Fi or mobile data.

3. Turn on the head sensor. Create User Account and Profile in it. Add Sensor to the Profile.

4. If you cannot add sensor to the Profile (sensor cannot connect to the App), you must always use Active scanning to connect to the sensors. You can do this by tapping on “Menu” (3 bars on top of each other in the left upper hand corner of the screen) > Click “Start active scanning” > try adding sensor again to the profile. Active scan is on until you stop it by clicking on “Stop active scanning” .

5. In some rare occasions, we found that adding sensor to the profile was possible in passive scanning mode, but the sensors didn’t connect without active scanning after this. So ensure your mobile device’s scanning mode to use with creating another test impact after you have successfully added sensor to he profile. If also now you get the event information to the App without using Active  scanning, your mobile device works on passive scanning. If your mobile device is not connecting to the sensors automatically, you must use Active scanning always when you want to connect to the sensors, and receive information from the sensors.

PASSIVE SCANNING

Passive scanning means that App is automatically connecting to the ACT Head Impact Trackers when the sensors are trying to send information. Unfortunately the mobile device brands and models are increasingly banning the passive scanning use and currently we have found that only majority of Samsung mobile devices work with passive scanning.

Occasional problems with establishing and maintaining connection between the head sensors and mobile devices (no notification to the App regarding) were recorded:

– Samsung phones: a.) in some models Bluetooth® wireless connection was slow, even disconnected, if the mobile phone’s screen is switched off (= not lighted). The connection should be re-established and information from the sensors delivered when the screen is switched back on (=lighted) if the sensor(s) are in the reach of Bluetooth® wireless technology. b.) In all models pop-up window with list of devices for paring appears when Bluetooth® wireless technology is switched on. When this happens, just click “Continue” to close the window. No paring is needed, nor appearing nor choosing it on the list. Also in few occasions the phone just disconnected Bluetooth® wireless connection. If the listening sensors just stops, turn Bluetooth® wireless connection off and back on, this fixed the problem.

ACTIVE SCANNING

When Passive scanning is not working, you need to use active scanning to allow sensors to connect to the mobile device and ACT App.  Active Scan works like this: 

1. Click “Menu” (3 bars on the left upper hand corner) > Click “Start active scan” > Text turns to “Stop active scan” = Active scanning is on until you switch it off by clicking “Stop active scan”. 

2. When the text is “Start active scan” = Active scanning is not on. 

3. If needed, always use active scanning when you want to connect to the sensors.

We have not yet tested any mobile device running Android 10 or newer which does not work with Active scanning. But we have not tested all the brands and models available, nor all of their operating system and update versions, so we cannot guarantee that ACT Head Impact Tracker mobile App will work with every mobile phone brand and model.

iOS App is not yet available. The plan for iOS App launch is in the summer of 2024.
