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. Generally stated, the most important requirement is that the benefits of the technology outweigh the negative properties, and that it is a better alternative to already existing aids. It can be better in terms of cost, usability, etc. The benefits mainly come down to support for their disability. Negative factors can be the costs, the usability, etc.
Different designs
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%
