  1. 1. On sensory feedback in hand prostheses

    Author : Christian Antfolk; Avdelningen för Biomedicinsk teknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Prosthetic hands; sensory feedback.;

    Abstract : Amputation of the hand implies the loss of the ability to grasp and the ability to "feel". The grasping function can be primitively restored using an active prosthesis. Multi­articulating electrically powered hands have recently made their way to the market and these hands provide enhanced grasping and gripping capabilities. READ MORE

  2. 2. Sensory integration : success & failure

    Author : Tamas Jantvik; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technology - Electrical engineering; electronics and photonics; Teknikvetenskap - Elektroteknik; elektronik och fotonik; Industriell elektronik; Industrial Electronics;

    Abstract : The convergence of sensory signals plays an important role in perception. Two cases of convergence are examined in this thesis by means of modelling; the case when the converging signals are congruent, which leads to combination and an enhancement of perception, and the case when they are incongruent.

  3. 3. Towards clinically viable neuromuscular control of bone-anchored prosthetic arms with sensory feedback

    Author : Enzo Mastinu; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Electromyography; prosthetics; sensory feedback; closed-loop; osseointegration; embedded system; pattern recognition; neurostimulation;

    Abstract : Promising developments are currently ongoing worldwide in the field of neuroprosthetics and artificial limb control. It is now possible to chronically connect a robotic limb to bone, nerves, and muscles of a human being, and to use the signals sourced from these connections to enable movements of the artificial limb.

  4. 4. The language learning infant: Effects of speech input, vocal output, and feedback

    Author : Lisa Gustavsson; Francisco Lacerda; Roger Moore; Stockholms universitet; []
    Keywords : HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; human; language; language acquisition; perception; production; humanoid; development; model; embodied system; speech signal processing; vocal tract morphology; acoustic; speech input; information processing; scaling; interaction; growth; infant; imitation; feedback; perceptual salience; modeling; Phonetics; Fonetik; Phonetics; fonetik;

    Abstract : This thesis studies the characteristics of the acoustic signal in speech, especially in speech directed to infants and in infant vocal development, to gain insight on essential aspects of speech processing, speech production and communicative interaction in early language acquisition. Three sets of experimental studies are presented in this thesis. READ MORE

  5. 5. Towards a tactile artifical hand

    Author : Ulrika Wijk; Malmö Handkirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES; amputation; upper limb; phantom hand map; sensory feedback; referred sensation; hand prosthesis; body ownership; tactile sensation;

    Abstract : Amputation of a hand is a life-changing event, and the loss of motor and sensory functions leads to disability and has devastating effects on the individual. What is normally performed using two hands must be solved with only one, and the loss also affects body balance and body posture. READ MORE
