  1. 1. Look2Hook - A Comparative Study of Eye-tracker and Mouse Based Object Selection in a Complex Environment

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Oskar Erlandsson; [2021]
    Nyckelord :Eye-tracking; dwell-time; confirmation click; Midas touch; map environment; eye-tracker selection; Eye-tracking; dwell-time; bekräftelseklick; Midas touch; kartmiljö; eye-tracker selektion;

    Sammanfattning : In this thesis the Tobii eye-tracker 4L was used to investigate how well eye-tracking solutions such as a confirmation-click and dwell-time algorithm compares to the standard mouse input device when performing selection tasks in a map environment. In order to distinguish the different complexity one could face, two user cases are proposed. LÄS MER

  3. 2. Photometric stereo for eye tracking imagery

    Master-uppsats, Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska högskolan

    Författare :Robin Berntsson; [2017]
    Nyckelord :Photometric stereo; head pose estimate; shape from shading;

    Sammanfattning : The goal of this work is to examine the possibility of surface reconstruction from the images produced by the Tobii H5 eye tracker. It starts of by examining classic photometric stereo and its limitations under the illuminator configuration of the eye tracker. LÄS MER

  4. 3. Facial Feature Tracking and Head Pose Tracking as Input for Platform Games

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för kreativa teknologier

    Författare :Anders Tobias Andersson; [2016]
    Nyckelord :facial feature tracking; head pose tracking; alternative interface; real-time; hci; human computer interface;

    Sammanfattning : Modern facial feature tracking techniques can automatically extract and accurately track multiple facial landmark points from faces in video streams in real time. Facial landmark points are defined as points distributed on a face in regards to certain facial features, such as eye corners and face contour. LÄS MER

  5. 4. Face Tracking Using Optical Flow : Real-Time Optical Flow Enhanced AdaBoost Cascade Face Tracker

    Master-uppsats, Högskolan i Halmstad/Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Författare :Andreas Ranftl; [2014]
    Nyckelord :Face; Tracking; Likelihood Map; Optical Flow; Viola-Jones; AdaBoost Cascade Classifier; OpenCV; C ; MEX; Boston Head Tracking Database;

    Sammanfattning : This master thesis deals with real-time algorithms and techniques for face detection and facetracking in videos. A new approach is presented where optical flow information is incorporatedinto the Viola-Jones face detection algorithm, allowing the algorithm to update the expectedposition of detected faces in the next frame.

  7. 5. A feature based face tracker using extended Kalman filtering

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Nils Ingemars; [2007]
    Nyckelord :face tracker; extended Kalman filtering; the Candide face model;

    Sammanfattning : A face tracker is exactly what it sounds like. It tracks a face in a video sequence. Depending on the complexity of the tracker, it could track the face as a rigid object or as a complete deformable face model with face expressions. This report is based on the work of a real time feature based face tracker. LÄS MER
