Starting a recording
You can start an AIRS recording either by pressing the green button in the AIRS app or by using a home screen shortcut. The recording will start in the mode you configured it for and with the settings you last used or the ones saved in the recording template (i.e., Local or Remote). After pressing the green button, the user interface will exit and a recording background service will be started (see more below). For the Local mode, the recorded values are stored in a secure SQLite database. For the Remote mode, AIRS will attempt to connect to the application server whose IP address is defined in the General Settings. For this, AIRS starts a background service, similar to the local recording mode.
Using Configuration Templates
AIRS allows for using recording templates, all with their own settings for polling intervals, sampling frequencies, and input types you want to record. This way you can use different templates for, say, holidays, work, car, or home scenarios.
For this, you find a list of current templates under the Record tab (here, we have the default template called Lifelogging). Clicking on any available entry will load this template entry, overwriting the current settings.
Once you select a certain template, you can either Delete it from the system, create a home screen Shortcut for quicker start of recording or Start recording from AIRS by pressing the green button. The shortcut (which will appear on the launcher screen) will have the name of the selected template and will be recorded through the TE sensor (you can therefore even record what recording template you were using!). Using the Download option you can get more templates from our server at TecVis. These templates provide you with some examples of what to configure for what type of scenario (see our web page on recording scenarios).
When you configure AIRS, you will have the chance to save a current configuration setting as a template, as shown here:
Checking the Current Recordings
It is possible to monitor the current local sensing session through the AIRS notification in the notification bar.You will see that the service is still running as well as the time of starting the service. Clicking on the notification opens the measurement window. In this window you can see information about all data being recorded: the sensor symbols, their current values and the unit of measurement.
A brief click on any of the rows will display a brief Toast notification with information about how many values have been sensed so far as well as the latest measurement with its timestamp. Note that there might be more values than can be shown – the dialogue window scrolls! If the particular sensor supports historical values, another window will pop up, showing the most recent historical values with timestamps. Most values are shown along a timeline, while the track of GPS coordinates is shown in a Google map view (with the option to center on the current location or the last recorded location).
A long click on any of the rows allows for sharing a string of the recent measurement via, e.g., Facebook, via Bluetooth, Google+ or other sharing providers. Simply long click on a row and wait for the dialogue “Share AIRS Measurements via:” to appear. Here, you can select the provider to share with. Next, you will see the string inserted into whatever sharing you selected (e.g., within a post of Facebook). AIRS appends a signature with its market link under the shared string (you can remove the signature, if you like).
Pressing the Menu option of your device shows the following menu:
Apart from showing the About dialogue, you can Pause and Resume the measurements (this halts and resume the measurement threads) as well as Exit the local sensing session (this stops the service and closes down all resources used).
When pressing Exit, you will be presented with the following dialogue box. Apart from confirming your selection with Yes or No, you can also select Yes & Share. This option exits the measurement and presents you with a dialogue box to share the measurement file via options like Bluetooth, GMail, eMail, Facebook or other software that you might have installed on your device. You can use this option to backup your recent measurements to your own storage place.
