2. 1. Visual Flow Display for Pilot Spatial Orientation

   Author : Lars Eriksson; Claes von Hofsten; David Lee; Uppsala universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Optic flow; visual flow; peripheral vision; spatial orientation; spatial disorientation; postural control; somatogravic illusion; human centrifuge; flight displays; head-up display; head-mounted display; Psychology; Psykologi; Psychology; psykologi; Psykologi;

   Abstract : Pilot spatial disorientation (SD) is a significant cause of incidents and fatal accidents in aviation. The pilot is susceptible to SD especially in low visibility when the visual system is deprived of information from outside the cockpit. READ MORE

4. 2. Is seeing just believing? Measurement properties of visual assessment of Postural Orientation Errors (POEs) in people with anterior cruciate ligament injury

   Author : Jenny Älmqvist Nae; Institutionen för hälsovetenskaper; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; knee injury; Lower extremity; Anterior Cruciate Ligament; orientation spatial; Postural orientation; Performance-based measures; Reproducibility of results; Hop performance; Patient reported outcome measures;

   Abstract : Rupture of the anterior cruciate ligament (ACL) is a common knee injury among young physically active populations. The injury results in impaired physical functions, such as joint instability, limitations in daily activities and sport-specific activities, and worse movement quality, e.g., altered postural orientation.

5. 3. Spatial Vision in Bees : Behavioural investigation of spatial resolution and contrast sensitivity

   Author : Aravin Chakravarthi; Funktionell zoologi; []
   Keywords : Insect vision; Honeybees; Bumblebees; Spatial resolution; Contrast sensitivity; Motion detection; Object discrimination;

   Abstract : Bees use multiple sensory modalities to perform day-to-day tasks. Light allows them to perceive objects and the general features of their surroundings, enabling them to find food and to navigate safely across the landscape. READ MORE

6. 4. Spatial domain methods for orientation and velocity estimation

   Author : Gunnar Farnebäck; Gösta Granlund; Linköpings universitet; []
   Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : In this thesis, novel methods for estimation of orientation and velocity are presented. The methods are designed exclusively in the spatial domain.Two important concepts in the use of the spatial domain for signal processing is projections into subspaces, e.g. READ MORE

7. 5. Effects of Art and Design on Orientation in Healthcare Architecture : A study of wayfinding and wayshowing in a Swedish hospital setting

   Author : Muna Ibrahim; Institutionen för arkitektur och byggd miljö; []
   Keywords : HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; health-care architecture; hospital design; interior design; public art; wayfinding; orientation; affordance; familiarity; wayshowing; heterogeneity; temporality;

   Abstract : This thesis investigates the role of interior design elements, especially artwork, in way-searchers’ wayfinding and orientation in hospital environments. The thesis considers the way-searcher’s background and the impact of cultural belonging, occupation, memories, aesthetic preferences, and language, and the influence that such factors might have on the perception of the hospital environment and its guiding elements.
