Abstract 

- There are six folders corresponding to 6 types of BPPV disorders.

- Each folder has one sample.

 

Each class is specified by the typical movement of the eye.

 

+) Lt_Geo_BPPV: eye beats toward the ground, beats stronger to the left side (turn head left).

+) Rt_Geo_BPPV: eye beats toward the ground, beats stronger to the right side (turn head right).

+) Lt_Apo_BPPV: eye beats toward the sky, beats stronger to the left side (turn head right).

+) Rt_Apo_BPPV: eye beats toward the sky, beats stronger to the right side (turn head left).

+) Lt_PC_BPPV: eye beats slightly up and rotates clockwise (often at hanging left position).

+) Rt_PC_BPPV: eye beats slightly up and rotates counter-clockwise (often at hanging right position).

 

- Each folder contains a video (*.avi format) and a temporal labeled file (*.mat format).

- The '*.mat' file can be read by matlab, that stores the 'fr' and 'label' variable.

- Each action of the patient is labeled with the start and end frame ID. 

- Actions are marked as follows:

  +) 'sitting' is labeled as '1'

  +) 'head turns left' is labeled as '2'

  +) 'head turns right' is labeled as '3'

  +) 'head hanging left' is labeled as '4'

  +) 'head hanging right' is labeled as '5'

  +) 'lying down' is labeled as '6'

  +) 'head bending' is labeled as '7'

 

 

An example: postures of patient are labeled in the 'Class2_100030.mat' (Lt_Geo_BPPV folder) as follows:
