2. 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

4. 2. Sensory integration : success & failure

   Author : Tamas Jantvik; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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.

5. 3. Touching on elements for a non-invasive sensory feedback system for use in a prosthetic hand

   Author : Pamela Svensson; Avdelningen för Biomedicinsk teknik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sensory feedback; amputation; referred sensation; non-invasive feedback; upper limb prosthetics; body ownership;

   Abstract : Hand amputation results in the loss of motor and sensory functions, impacting activities of daily life and quality of life. Commercially available prosthetic hands restore the motor function but lack sensory feedback, which is crucial to receive information about the prosthesis state in real-time when interacting with the external environment.

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

   Author : Enzo Mastinu; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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.

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

   Author : Lisa Gustavsson; Francisco Lacerda; Roger Moore; Stockholms universitet; []
   Keywords : 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
