Abstract:

The most common navigation aid visually-impaired people employ is a white cane, but, recently, technology has given rise to a varied set of sophisticated navigation aids. While these new aids can provide more assistance to a visually-impaired person than a white cane, they tend to be expensive due to a small market segment, which in turn can reduce their accessibility. In an effort to produce a technologically-advanced yet accessible navigation aid, an Android application is proposed that detects and notifies users about obstacles within their path through the use of a smartphone's camera.

Abstract:

La mobilità autonoma per le persone ipovedenti e non vedenti può essere molto difficile e spesso richiede l'uso di dispositivi di supporto, come il bastone bianco. Nel corso degli ultimi decenni sono stati proposti numerosi dispositivi elettronici con lo scopo di fornire al non vedente delle informazioni sull’ambiente circostante utili alla deambulazione. Ad oggi nessuno di essi soddisfa appieno i requisiti delle linee guida internazionali definite per gli ETA. Si è pensato quindi di studiare un ausilio innovativo basato su impulsi elettromagnetici, ancora mai impiegati per questo scopo

Abstract:

Serious games are games designed to entertain and also to teach or transmit some knowledge. They are present in many areas such as military, health, manufacturing, education or medicine, just to name a few. One of their main advantages is their capability to recreate scenarios to experiment with situations that otherwise would be impossible in the real world due to required safety, cost, and time. In addition, serious games enhance the development of analytical and spatial, strategic, or psychomotor skills. Unfortunately, despite the advantages of serious games there are still some aspects th

Abstract:

The long white cane offers many benefits for the blind and visually impaired. Still, many report being injured both indoors and outdoors while using the long white cane. One frequent cause of injury is due to the fact that the long white cane cannot detect obstacles above the waist of the user. This thesis presents a system that attempts to augment the capabilities of the long white cane by sensing the environment around the user, creating a map of obstacles within the environment, and providing simple haptic feedback to the user. The proposed augmented cane system uses the Asus Xtion Pro Live

Abstract:

This paper investigates feasibilities of technological solutions for empowering visually impaired and blind people to travel in outdoor environments independently. Through related work on users'spatial models, usage of long white canes, and existing technological aid tools, an in-depth understanding of users and problems of independent travel is developed. The main constituents of the independent travel are object detection, navigation, and orientation. While long white canes are very useful for supporting visually impaired and blind people to travel independently, the usefulness is limited to
