The results indicated that adaptive environment enhanced user effectiveness in tasks completion up to 20% and increased their efficiency up to 8%. Two separate groups consisting 30 colour-blind users and another same sample of colour deficient users performed three different tasks in non-adaptive and adaptive environment. To simulate the visual abilities of user, the Ishihara test is performed in start. A research application has been developed which detects the colour-blindness types and automatically switch to respective colour mode. This paper explores the possibility to transform static interfaces into adaptive user interface which automatically change its behaviour according to user requirements. Today the devices are becoming smarter in recognizing user limitations and operating systems in Mobile-phones are providing such services which help user in their own context to overcome their barriers in usage of information and communication technologies. It has broader impact as 8% (1 in 12) men and around 0.5% (1 in 200) women are facing this challenge. Different kinds of static and dynamic visual variables can be considered as matter of investigation for future research to represent flow of vehicle in the cities, especially for CVD.Ĭolour-blindness or Colour Vision Deficiency (CVD) is not a disability rather it is naturally challenging vision problem in which user feel difficulty in distinguishing different colours especially differentiating among blue and yellow or red and green colours. Additionally, dynamic maps showed a higher level of satisfaction than static maps for groups of NCV and CVD. Higher efficiency was found with the use of dynamic maps among participants having NCV, and higher efficiency was found with the use of static maps among participants having CVD. The results showed that the efficacy was similar between the NCV and CVD participants when they were using static or dynamic maps. The maps were displayed individually in a tablet with a size of 7 inches, and each task lasted up to 30 seconds.
In an experiment conducted in laboratory, the participant's tasks were select and draw routes between origin and destination places shown on maps. An area located in the city of Presidente Prudente, state of São Paulo, was selected to design eight static maps and eight dynamic maps at 1:5,000 scale. This work aims to evaluate and compare the usability (effectiveness, efficiency, and satisfaction) of static and dynamic flow maps reading which were represented by using ordered hues, with 10 people having CVD and with 10 people having NCV. The scientific research about reading flow maps by people having NCV or CVD is not clearly established, mainly when considering the perceptual properties present in the static and dynamic visual variables. A cartographic representation for different vehicle's flows with color hue variation, ideally, could be well succeed for users having Normal Color Vision (NCV) or having Color Vision Deficiency (CVD).
Finally, we evaluated directions for future compensation methods for computational glasses.įlow maps represent data over time that connect different locations.
COLOR ORACLE REVIEW PORTABLE
In this work, we present an exhaustive literature review of colour vision deficiency compensation and subsequent findings several prototypes with varying advantages-from well-controlled bench prototypes to less controlled but higher application portable prototypes and a series of studies evaluating our approach starting with proving its efficacy, comparing to the state-of-the-art, and extending beyond static lab prototypes looking at real world applicability. While existing research only showed corrected images within the periphery or as an indirect aid, Computational Glasses build on modified standard optical see-through head-mounted displays and directly modulate the user’s vision, consequently adapting their perception of colours. In our work, we report on research on Computational Glasses for compensating colour vision deficiency. Colour vision deficiency is a common visual impairment that cannot be compensated for using optical lenses in traditional glasses, and currently remains untreatable.
