Problem Statement

People with a visual impairment will never be able to sense the world as people without visual impairment. Thanks to guide dogs and white canes, however, these people are able to enjoy independence when it comes to navigating outside areas. Yet, these measures cannot give a representation of the world around them beyond the range of the cane or the movement of the dog. With the use of technology that might change. Using sensors these people could be given the ability to sense more than their immediate surroundings, sense objects which their white cane didn't contact or the dog ignored because it was not in the way.

Users

The users we are designing the technology for, are the visually impaired. People with a visual disability often need aids to get through their daily life. For a blind or partially blind person, the simplest tasks can be hard to complete. While there are existing tools, such as guiding dogs and white canes, these are not always sufficient.

The most important requirement of the technology is that it offers a valid alternative to existing aids. This does not necessarily mean that the technology better support the users disability than alternatives, it could also mean that it is simply cheaper. If the product is cheaper it can still be an option for people not able to afford more costly alternatives. There are many factors classifying the value of a product. Two important factors are the production and selling costs, and the support given and the usability of the technology.

Different designs

gloves

shoes

Bril?

Geluid toevoegen zoals vleermuizen? -> Doppler effect gebruiken voor bewegingen. -> dit kan gedaan worden met icm radar -> groot bereik

Deliverables

A prototype that aids blind people roam around areas, that are unknown to them. This prototype is based on the design of last year[1]. From this design, a new design was made that tries to improve on the issues the previous design faced. Additionally, a wiki will be made that helps with giving additional information about the protoype, such as costs, components and it gives some backstory of the subject. Finally, a presentation is made regarding the final design and prototype.

Requirements

Approach

To build this prototype designed for the users, in this case, the visually impaired, first there has to be known what the actual problem is. To acquire this knowledge, information about problem is gathered. Afterwards, using this problem, information about the state-of-the-art of most notably technologies for visually impaired, radar-sensors and radar-Doppler-sensors could be gathered. Combining all the information will be used to make preliminary design that fills the needs of the users. After the preliminary design is finished, building the prototype can be started. During the making of the design and building the prototype, it is probable that some things might not go as planned and it will be necessary to go back steps, to make an improvement on the design in the end. When the prototype is finished, it is tweaked to perform as optimal as possible using several tests. Finally, everything will be documented in the wiki.

Milestones

  • Completing the design of the prototype
  • Finish building the prototype
  • Prototype is fully debugged and all components work as intended
  • Prototype follows requirements
    • 50%
    • 75%
    • 100%

[9] Bril maakt 3d-interpretatie van omgeving waar naar gekeken wordt, hiermee wordt een soundscape gegeven. Kan gecombineerd worden met riem met vibraties voor meer omgevingsgewaarwording. [10] Research dat gebruikt wordt in vorige referentie; Probeert een zo goed mogelijke interpretatie van de wereld in de vorm van geluid te maken. Expliciet is genoemd dat deze research niet gericht is op obstacle-avoidance. Maar, kan wel interessant zijn op hoe hun stimuli gebruiken om de omgeving te omschrijven. (Hoe laten we iets vibreren om iets duidelijk te maken?) [11] Research precies naar wat wij willen doen, object identification met geluid en vibratie. Neemt ook bewegende obstakels into account. [12] Proposal van detectiemethode bij smart gloves. Belangrijkste conclusie: The limitation of this project was the ultrasonic sensor used can only detect the obstacles but cannot illustrate the shape of the obstacles. [13] Eind proposal: Arduino-powered bracelet voor vibraties om hiermee bewegingen te sturen. [14] Ook een middel om visuele dingen om te zetten naar geluid, dit keer óók voor obstacle avoidance.
