  2. 1. Evaluating the Effects of Variation on Product Appearance through Visual Robustness

    Author : Karin Nordvall; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; product experience; visual quality appearance; visual sensitivity; optical quality; industrial design; perceived quality; craftsmanship; robust design; non-nominal visualization; geometrical variation; visual robustness;

    Abstract : For consumer products where the product appearance plays an important role in meeting expectations, the visible effects of manufacturing variation can have a negative influence on the product experience. A concomitant of mass production is that no manufactured units are exactly identical, as a result of variation. READ MORE

  4. 2. Visualising the Effect of Geometrical Variation in Assembled Products. Predicting Visual Quality Appearance

    Author : Casper Wickman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tolerancing; visual quality appearance; distance perception; empirical studies; method development; visual sensitivity; and geometric variation; virtual reality;

    Abstract : Today, when an industrial design concept is evaluated in an aesthetic manner, little or no consideration is given to geometrical variation, i.e. the concept is evaluated with nominal geometry. READ MORE

  5. 3. Visual filtering in box jellyfish: A simple system

    Author : Megan O'Connor; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tripedalia cystophora; box jellyfish; Cnidaria; Chiropsella bronzie; visual filtering; visual systems; microspectrophotometry; vision; eyes;

    Abstract : Unlike most jellyfish, box jellyfish (cubomedusae) are highly visually orientated. They are agile swimmers and use visual information to avoid obstacles and orientate themselves. READ MORE

  6. 4. Vision Beyond the Fovea: Evaluation and Stimuli Properties

    Author : Abinaya Priya Venkataraman; Linda Lundström; Hema Radhakrishnan; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Peripheral vision; Visual optics; Optical correction; Orientation; Stimulus extent; Moving stimulus; Contrast sensitivity; Visual acuity; Central vision loss; Myopia; Biological Physics; Biologisk fysik;

    Abstract : This research is about evaluating vision in the periphery. Peripheral vision is of fundamental importance in the performance of our everyday activities. The aim of this thesis is to develop methods suitable for the evaluation of peripheral vision and to assess how different visual functions vary across the visual field. READ MORE

  7. 5. Improving Peripheral Vision Through Optical Correction and Stimulus Motion

    Author : Peter Lewis; Peter Unsbo; Linda Lundström; Jörgen Gustafsson; Michael Crossland; Linnéuniversitetet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; absolute central scotoma; central visual field loss; eccentric viewing; preferred retinal locus; open-view aberrometer; off-axis refractive errors; eccentric correction; dynamic visual acuity; spatial contrast sensitivity; temporal contrast sensitivity; spatio-temporal contrast sensitivity; Optometry; Optometri; Biomedical Sciences; Biomedicinsk vetenskap;

    Abstract : The loss of central vision subsequent to macular disease is often extremely debilitating. People with central field loss (CFL) must use other peripheral areas of the retina in order to see; areas with inferior resolution capacity, which are also affected by off-axis optical errors.
