There are 3 different clinical mental questionnaires which are General health, Hamilton Anxiety rating scale (HAM-A) and Beck Depression Inventory (BDI) where each of the questionnaires consists of questions related to body health, anxiety disorder and depression.

	The heartbeat discrimination task in the project is started with the subject to assess BK method which consists of 6 different delay intervals (range: 0-500ms; 100ms steps) heartbeat tones (10 tones, 800Hz frequency, 100ms duration) represented with 6 independent buttons and the subject is allowed to play the heartbeat tones for unlimited times. Then, the subject is required to choose the respective delay interval heartbeat tones that is synchronous with their heartbeat sensations. Next, the subject is required to assess Whitehead method which consists of 10 trials per task. For each trial, subject has to listened to the heartbeat tones (10 tones, 800Hz frequency, 100ms duration) that is either synchronous or asynchronous delay interval randomised by the app. Then, the subject is required to identify the heartbeat tones by choosing TRUE (synchronous with heartbeat) or FALSE (asynchronous with heartbeat) from the drop down input list from the assessment software user interface. By the end of the task, the subject’s estimated result and the actual heartbeat tones result are stored and a text file is created with the content of stored estimated and actual heartbeat tones results.

 In the project, Zephyr HxM BT is used as heart rate monitor and Google Nexus 7 is used as assessment software user interface and assessment result storage for heartbeat tracking task. The heartbeat tracking task for the project consists of 10 trials per task with 30 seconds heartbeat number counting duration for each trial. The 10 trials per task decision is made up after discussion with project supervisor, Professor Mathias where 10 trials per task duration is not too long which may cause frustration from the user and subject and at the same time it is able to provide sufficient data results for medical authorities to identify the subject’s assessment performance for subject’s mental symptoms identification.
- A tone with 800Hz frequency and 100ms duration created from Matlab is used to notify user or subject to start and stop counting their heartbeat number. Thus, the subject and Zephyr HxM BT has to start counting subject’s heartbeat number when the start tone is emitted via Nexus 7’s speaker and to stop counting subject’s heartbeat number when stop tone is emitted. After completion of each trial, subject is required to input their estimated heartbeat number into the given input box on the user interface of the app for result storage. After the completion of 10 trials by the subject, the heart rate monitor counted heartbeat number and subject’s estimated heartbeat number are stored and a text file is created with the content of stored counted and estimated heartbeat number results.

 '''Heartbeat Tracking Task'''
-Heartbeat tracking task is an assessment to allow user or subject to count their number of heartbeat within the specific duration by concentrating on bodily feelings associated with heart actions. Zephyr HxM BT shall count subject’s number of heartbeat at the same time where the counted heartbeat number is stored to compare with subject’s counted heartbeat number to identify the subject’s assessment performance.Heartbeat tracking task is a heartbeat perception method developed by researcher Rainer Schandry for his research article called “Heartbeat Perception and emotional experience” [1].
