1. 11. Steering control for haptic feedback and active safety functions

   Författare :Tushar Chugh; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; position control; coupled stability; passivity; steering system; uncoupled stability; transparency; active safety; haptic feedback; torque control; state estimation;

   Sammanfattning : Steering feedback is an important element that defines driver–vehicle interaction. It strongly affects driving performance and is primarily dependent on the steering actuator's control strategy. LÄS MER

3. 12. User Centered Design of Non-Visual Audio-Haptics

   Författare :Kirsten Rassmus-Gröhn; Certec - Rehabiliteringsteknik och Design; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Haptic; audio; non-visual; user-centered design; school; drawing; children;

   Sammanfattning : The following article reports result from an extensive study with 25 blind users from Italy and Sweden performed during the summer 2001. The tasks reported here test recognition of geometrical objects, recognition of VRML objects, mathematical surfaces and navigation in a traffic environment. LÄS MER

4. 13. A methodology for situated and effective design of haptic devices

   Författare :Xuan Sun; Kjell Andersson; Ulf Sellgren; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Design optimization; haptic devices; metamodel; multi-criteria; situatedness; Machine Design; Maskinkonstruktion;

   Sammanfattning : The realism of virtual surgery through a surgical simulator depends largely on the precision and reliability of the haptic device. The quality of perception depends on the design of the haptic device, which presents a complex design task due to the multi-criteria and conflicting character of the functional and performance requirements.

5. 14. 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.

7. 15. Direct Volume Haptics for Visualization

   Författare :Karljohan Lundin Palmerius; Anders Ynnerman; Matthew Cooper; David Ebert; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Haptic Visualization; Volumetric Data; Haptic Primitives; Shape Representations; Time-varying Data; Computer engineering; Datorteknik;

   Sammanfattning : Visualization is the process of making something perceptible to the mind or imagination. The techniques for producing visual imagery of volumetric data have advanced immensely during the last decades to a point where each produced image can include an overwhelming amount of information.
