Problem statement and objectives

Problem Statement

When encountering an environment as ever-changing and unpredictable as traffic, it is important for every traffic participant to have the widest range of information about the situation available to them, for safety reasons. Most roads are already covered in guiding materials: traffic lights, cross walks and level crossings have visual, tactile and auditory signals that are able to relay as much information to users of traffic as possible. Unfortunately, some user groups are more dependent on certain type of signals than others, for example due to disabilities. Not every crossing or road has all of these sensory cues, therefore it is important to find a solution for those user groups that struggle with this lack of information and therefore feel less safe in traffic. In specific, we are looking at visually impaired people, and creating a system/robot/design that will aid them in most traffic situations to cross roads, even with the lack of external sensory cues.

Main objectives:

• The design should be able to aid the user in crossing a road, regardless of external sensory cues already put in place, with the purpose of giving more autonomy to the user

• The design must have audible, or otherwise noticeable, alerts for the user, that are easily understood by said user

• The design must have a reliable detection system
• The design must be 'hidden': it should not disrupt the user's QoL and could be barely noticeable as technology
  • Ex. hidden in the user's clothing

An extended list of all features can be found at MoScoW part.

User Experience Design Research

For this project, we will employ a process similar to UX design:

• We will contact the stakeholders or target group, which is in this case visually impaired people, to understand what they need and what our design could do for them
• Based on their insight and literature user research, we will further specify our requirements list from the USE side
• Combined with requirements formed via the SotA research, a finished list will emerge with everything needed to start the design process
• From then we build, prototype and iterate until needs are met

Below are the USE related steps to this process.

USEr research

Target Group

Primary Users:

• People with affected vision that would have sizeable trouble navigating traffic independently: ranging from visually impaired to fully blind

Secondary Users:

• Road users: any moving being or thing on the road will be in contact with the system.
• Fellow pedestrians: the system must consider other people when moving. This is a separate user category, as the system may have to interact with these users in a different way than, for example, oncoming traffic.

Users

What Do They Require?

!!From user research we will probably find that most blind people are elderly. We can conclude somewhere here then that we will focus on elderly people, and that that will have implications for the USEr aspects of the design as elderly people are notorious for interacting and responding differently to technology.!!

Society

How is the user group situated in society? How would society benifit from our design?

Enterprise

What businesses and companies are connected to this issue?

Stakeholder Analysis

To come in closer contact with our target groups, we reached out to multiple associations via mail. The following questions were asked (in Dutch), as a ways to gather preliminary information:

Following these questions, we got answers from multiple associations that were able to give us additional information.

From this, we were able to setup interviews via Peter Meuleman, researcher and founder of Videlio Foundation. This foundation focusses on enhancing daily life for the visually impaired through personal guidance, influencing governmental policies and stimulating innovation in the field of assisting tools. Peter himself is very involved in the research and technological aspects of these tools, and was willing to be interviewed by us for this project. He also provided us with interviewees via his foundation and his personal circle.

Additionally, via personal contacts, we were also able to visit an art workshop at StudioXplo on the 7th of February meant for the visually impaired. We were able to conduct some interviews with the intended users on site.

Prototypes/Design

Here we will put some different versions of a design of what we think will be a solution. We can pick one to work on.
