title: Impact of skin abberations on face exploration behaviour: a HMM study

description: gaze fixation data from healthy participants observing faces with acne. Description of methods used for collection/generation of data: data were collected as described in Methods section of Jankowski M, Goroncy A. Perceptive Hierarchy of Facial Skin Lesions: An Eye-tracking Study. Acta Derm Venereol. 2022 Oct 24;102:adv00799. doi: 10.2340/actadv.v102.2514.Methods for processing the data: n/aInstrument- or software-specific information needed to interpret the data: not applicableStandards and calibration information, if appropriate: 9 point gaze calibrationEnvironmental/experimental conditions: room temperature, fixed luminanceDescribe any quality-assurance procedures performed on the data: People involved with sample collection, processing, analysis and/or submission: Marek Jankowski, Agnieszka Goroncy Krzysztof JasinskiDATA-SPECIFIC INFORMATION FOR: BR-Org-25-147 Matlab codethe main file \Matlab code\emhmm-toolbox-v0.80-20210910\emhmm-toolbox\demo\BR-Org-25-147_code.m is the modification of the original file \emhmm-toolbox-v0.80-20210910\emhmm-toolbox\demo\demo_vb_faces.m, (originating from: Hsiao, J.H., Lan, H., Zheng, Y., Chan, A.B.
