Wiki week 1

Problem statement

People with visual impairments have trouble navigating through space due to the absence of clear sight. Nowadays, they have to trust on their dog who is guiding them across the streets. This people have also a blind stick to feel what object are in their close environment. However, they can not feel if there is a doorstep or a lamppost at the same time, what can cause a insecure feeling. They have to walk slowly because of their short field of view. This problems make it intensive to walk outside. It also occurs that blind people don’t like dogs or even are allergic for them. Improvements for the way blind people are detecting the environment can be made. By means of this project a possibility for improvement will be examined.

Users

The users are people with visual impairments. If possible we will contact a person with visual impairments, so a potential user can influence the design of the product. The goal is to make a user-centered design.

Require

A device that helps people with visual impairments to navigate through space. The specific requirements are given in the table.

Deliverable

A prototype of the device will be made. Also a report of the project will be updated weekly on wiki.

Objective

Making a device that makes it more easy and less intensive for blind people to navigate through space.

Approach

An user-centered design (if possible) of a device that helps blind people navigating through space. This can be done by making a device that gives more information about the close environment of the user. The user have to get information about obstacles by their feet and head/other body parts at the same time. A point for orientation is needed so the user knows in which direction he/she walks. To know what the best options are to make device easy and comfortable to use a blind person will be contacted. After designing a device that meets the requirements a prototype of this device will be made. For this, the following milestones have to be achieved:

Milestones

- Literature study

- Finishing the design of the prototype

- Components for prototype are arrived

- Device is built and the software is made

- The device works and functions well (functioning testing)

- The device is usable (usability testing)

Who’s doing what and roles

Eline : Designing, usability testing, literature study - point of contact

Stefan: Programming, literature study - checks the planning

Tom: Assembling, selecting products, literature study - prepare meetings

Bruno: Assembling, selecting products, literature study - making minutes

Evianne: Human-machine interactions, designing, usability testing, literature study - checks wiki

Literature research

The topics needed for the project are split up. Everybody have a direction at which he/she gathers information.

Eline: - usability testing, universal design

Evianne: - Just Noticeable Difference, human skin, ethics

Bruno: - electromagnetics, Hall effect? (car sensors)

Tom: - mechanics compass, optische sensors

Stefan:- (digital) compass, infrarood

State-of-the-art

From the literature research we learned that…..samenvatting!
