Abstract
Visual Impairment persons have the disadvantage when they try to walk straight without any active or passive guidance. They usually tend to walk with circle path how hard they try, this is called veering behavior and it is nature in human instinct. For walking, most visual impairment persons will use at least a support cane for their walking guidance. In Running Athletics para-competition, visual impairment athletes did not use a support cane, they will use human assistant and run together beside them. The athletes will hold tether where the other end were held by the assistant, whose called sighted guide. Some visual impairment school in Indonesia have some difficulties to train their runner athletes, one of them is the limitation of human running assistant provide by them. Blind Runner Guide Android Mobile Application offering one great feature for the visual impairment persons. This application will assist users to stay straight during their walk or run. This application still however can only be used for straight run competition, not circle athletic path which is usually used in international standard competition. This paper review the Visual Impairment user experiences using the application. From the experiment results shows that the application could reduce more than 50% percent of veering behavior. Experiment results from the short version UEQ shows 1.625 mean pragmatic quality score (good benchmark), 0.625 hedonic quality score (bad benchmark), and 1.17 overall quality score (above average benchmark).
Highlights
As of 2015, almost 1/7 people on earth having a variant type of visual impairment [2]. 250 Million people are on low vision and almost 40 million are totally blind
World Health Organization (WHO) estimates that most of visual impairment persons is preventable with some treatment and medication
Some mobile application developed to assist visual impairment people, such as Corsair GPS, Cydallion, Lazarillo, ANGEO, etc. these application can assist with some navigation, since they are using MAPS API provided for public such as Google Maps API or OSM API
Summary
The path usually will make circles route how hard the blind person try to walk straight [4] This sections discuss other blind guidance mobile application and other related previous study. The GPS will locate visual impaired users in outdoor environments This will guide them through the routes, and providing some information about closed points of interest. They claimed that the previous system is using compass as the sensors and have very limited capabilities due to influenced by magnetic inference from environment, e.g. cars, power transmission lines, or even human heart signals This application tends to assist visual impaired user on their walks, which is often distracted by many magnetic field in the pedestrians’ path. The model is demonstrated to have an overall accuracy of 84%, with accuracy as high as 90% for obstacles within 50cm in front of the user [12]
