BISE Dataset-Balinese Script for Imaginary Spelling using Electroencephalogram Signals

Description

Balinese Script for Imaginary Spelling using Electroencephalogram (BISE dataset) is a collection of data related to pronunciation/spelling and imagination of Balinese script based on electroencephalogram (EEG) signals. This dataset consists of character spelling (CS) and character imagination (CI) datasets. Providing CS and CI datasets is very important to ensure that the EEG signal pattern for the spoken script matches the imagined script. So, this dataset would actually need to be provided. In addition, previous researchers have yet to collect a Balinese script imagination dataset. The participants used as samples in this study were 31 healthy people, 8 males and 23 females, from students of the Balinese language education study program at Universitas Pendidikan Ganesha. The participants' EEG signals were recorded using Contec KT 88 with 16 channels. This dataset consists of 7 types of data, namely: (1) Raw data from the 1st experiment, (2) Raw data from the 2nd experiment, (3) Data analysis of character spelling (CS) in 1st experiment, (4) Data analysis of character imagination (CI) in 1st experiment, (5) Data analysis of character spelling (CS) in 2nd experiment, (6) Data analysis of character imagination (CI) in 2nd experiment, and (7) Raw data from calm conditions. The first experimental data contains EEG signal data from participants experimenting with pronouncing and imagining 18 Balinese scripts sequentially and randomly. Furthermore, the raw data of the second experiment contains EEG signal data from participants who performed the spelling (CS) and imagining (CI) of 6 Balinese vowel scripts sequentially and randomly. Furthermore, from the raw data, a data analysis process was carried out for the raw data in the 1st and 2nd experiments. In the first experiment's raw data, two analysis data were produced for 18 Balinese scripts spelling and 18 Balinese scripts imagined. Furthermore, for the raw data in the 2nd experiment, two analysis data were produced for 6 Balinese vowel scripts that were spelling and 6 Balinese vowel scripts that were imagined. Finally, the raw data of the calm condition contains EEG signal data from participants in a quiet condition before starting the experiment.

Steps to reproduce

a. Preparation of research documents Some documents that must be prepared to collect EEG signal data in this study include: 1) Research information documents, 2) Consent Form, 3) Preparation of health information b. Preparation of stimulus media This study will use two types of stimulus media, namely Balinese script stimulus media. This stimulus media is in the form of alphabet images containing speech sounds. Each participant will be asked to pronounce all Balinese letters. Through this scenario, an EEG signal pattern related to Balinese letters can be produced c. Submission of ethical permission To ensure that the recording process runs well and smoothly and minimizes its negative impact on participants, the research team proposes ethical permission for this recording. The following is the ethical permission that has been approved by the Faculty of Medicine, Ganesha University of Education d. Determine participants The procedure for determining participants is based on research conducted by Koelstra et al, Katsigiannis and Ramzan, and research conducted by Miranda Correa et al. e. Recording process This scenario is carried out in 2 cycles for each participant, with different recording times and days. Each participant in each scenario will practice spelling and imagining the Balinese alphabet based on the stimulus media provided.
