  1. 1. Tracking the Mind's Eye : Eye movements during mental imagery and memory retrieval

    Författare :Roger Johansson; Kognitionsvetenskap; []
    Nyckelord :HUMANIORA; HUMANITIES; Mental Imagery; Eye Movements; Eye-tracking; Encoding; Recall; Memory Retrieval; Episodic Memory;

    Sammanfattning : This thesis investigates the relationship between eye movements, mental imagery and memory retrieval in four studies based on eye-tracking experiments. The first study is an investigation of eye movements during mental imagery elicited both visually and verbally. LÄS MER

  3. 2. Detailed analysis of slow oscillatory movements of eye position

    Författare :Bing Zhang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Our eyes make continuous movements even when attempting to fixate a stationary object. The involuntary eye movements occurring during fixation are referred to as fixational eye movements. There is a general agreement on three types of eye movements occurring during visual fixation: tremor, drift and microsaccade. LÄS MER

  4. 3. A Position Control-based Approach to Stiff Objects Haptic Rendering

    Författare :Yang Wang; Kjell Andersson; Lei Feng; Anders Robertsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; haptic rendering; position control-based approach; rigid-body interaction; Machine Design; Maskinkonstruktion;

    Sammanfattning : With electronic components and computational power becoming more portable and available to general consumers, applications like virtual reality (VR) and mixed reality (MR) are on the rise and renovating the industry of training simulators. Though it is not fully accepted in surgical robots, haptic force feedback can be safely introduced into various surgical training simulators to convey the necessary haptic cues needed to develop hand-eye coordination and motor skills.

  5. 4. Evaluation of the infrared reflection method for saccadic eye movement velocity analysis

    Författare :Frank Träisk; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Infrared reflection; Scleral search coil; Saccade; Main sequence; Eye-tracking.;

    Sammanfattning : Saccades are rapid eye movements that change the orientation of the eyes onto objects of interest. In an every day situation saccadic eye movements are used for e.g. reading, scanning objects and enviromnents. LÄS MER

  7. 5. Effects of eye and neck muscle proprioception on ocular motor control in normal and strabismic subjects

    Författare :Ying Han; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :strabismus; binocular function; proprioception; eye position; muscle vibration; eye muscle; neck muscle; hand pointing; accommodative vergence movement; dynamics;

    Sammanfattning : Abundant proprioceptive information originates in eye and neck muscles but their role in normal visual function is unknown. Under experimental conditions, proprioceptive activation induces illusory visual movement, whereas clinical evidence indicates that proprioceptive dysfunction causes disturbances in spatial orientation.
