Context Analysis

Users Goals and Needs

In the research project AccessibleMaps, we address an user-centered design approach where the target group is involved in every phase of the development process. By designing user friendly and accessible applications, the human being as a user of technology moves more into the focus. In order to develop a better understanding of the target group as well as their goals and needs, various methods are used in usability research. In AccessibleMaps we developed Personas for this purpose, which are intended to reflect the needs and requirements of the target group.

Personas are fictional people of the target group who have goals, needs, skills and characteristics like real users. The persona’s challenges and current behavior are also described. Personas thus represent a major part of the future users. Different personas can therefore be developed for an application, each reflecting different perspectives and needs. Based on the personas, concrete usage scenarios are discussed in the further development process, which can be directly addressed by the later application.

The six personas listed below represent the addressed user groups of the research project AccessibleMaps. They are based on research findings from our online study, personal contacts, and interviews with people in the target group, as well as existing research findings from the literature. We developed two personas each for people with blindness, visual impairments, and people with mobility impairments to reflect the different needs.

Toni, 55 years, blind

Reluctant, uncertain

I have difficulties finding my way around buildings without assistance. Clear, tactile maps could help navigating more easily in a building or to find planned or already walked routes again.

Toni, 55 years, blind
About the person

Toni has been blind since childhood and has very good Braille skills. Whenever possible, Toni tries to explore the world tactilely. Toni visits office buildings, train stations, restaurants and shopping malls several times a year but usually in company of an assistant who helps with finding the way. Without the assistance, Toni feels uncomfortable because on-site help is often not available or detectable. For Toni, navigation applications are usually too cluttered and complicated, so that it is difficult to use the corresponding applications.

Personas: People with visual impairments

Mika, 25 years, severely visually impaired

Confident, self-assured

Many buildings and routes are insufficiently labeled; Lettering is incorrectly placed or too small. Mostly, however, these are essential, which makes orientation difficult.

Mika, 25 years, severely visually impaired
About the person

Mika acquired the visual impairment early in life and learned to cope with it well. Although Mika’s sense of sight is severely limited, their Braille skills are only rudimentary. Mika prefers to use tactile black lettering or large lettering. If Mika cannot read something, the smartphone is taken to hand. Mika often visits unfamiliar buildings, such as Office buildings, shopping malls, train stations and restaurants. Mika uses many apps that assist with reading labels aloud, for example. It annoys Mika that many different applications are necessary for this purpose.

Experiences and Skills
  • Braille Skills: few
  • Orientation: sure / good
  • Maps: high
  • Technology: high
Goals and Motivation
  • Receiving helpful and accessible information about buildings (digital or tactile maps, descriptions)
  • Receiving helpful features and information in one app
  • Getting assistance in recognizing signage
  • Getting information about barriers in buildings
  • Being assisted with finding the way
Assistive Technology

Mika uses different smartphone apps e.g., for reading aloud, sometimes also an electric magnifier or a tablet with headset

Behavior
  • no or same – day planning with the help of digital maps and descriptions
  • no planning, because available materials are either not helpful or not accessible
  • independent, explorative search for routes in buildings or usage of a map (digital, tactile)
  • Uses outdoor navigation applications: textual
  • Descriptions preferred for navigation, sometimes visual
Challenges
  • Signage in buildings that is too small, poorly placed (e.g., too high), or missing
  • Different heights of stairs, curved and complex buildings
  • Frequent switching between apps for different assistive applications

Reserved, insecure

I often feel unsafe in unfamiliar buildings because I have orientation problems due to too small print or poor illumination.

Glenn, 61 years, severely visually impaired
About the person

Glenn receives early retirement and got the visual impairment late in life, so Glenn has not had any mobility training yet. Glenn rarely goes into unfamiliar buildings, such as shopping malls, train stations, restaurants or cultural institutions, as this is usually associated with uncertainty for Glenn. When accompanied by an assistant, Glenn feels safer. If necessary, Glenn also visits familiar buildings on their own. When Glenn has to find a way alone, usually other people are asked or Glenn uses maps for orientation.

Sandy, 38 years, mobility impaired

Reserved, insecure

I often plan trips well in advance, as I have to gather information on the accessibility of buildings from various sources. Often, I could only find out on site that a building is not wheelchair accessible.

Sandy, 38 years, mobility impaired
About the person

Sandy is mobility impaired after an accident, and is therefore only able to travel very short distances without a wheelchair. Sandy plans visits to unfamiliar places, such as office buildings or medical facilities, shopping malls or hotels several days or weeks in advance. When Sandy needs to go into an unfamiliar building, it is often difficult to get the necessary information to assess whether a building is accessible or not. Sandy often struggles with navigating, finding and remembering an accessible route inside buildings independently.

Experiences and Skills
  • Mobility: restricted
  • Orientation: medium
  • Maps: medium
  • Technology: few
Goals and Motivation
  • Getting information about the wheelchair accessibility of buildings before the trip
  • Receiving information about accessible routes and location of elevators, etc.
  • Becoming more flexible and spontaneous when traveling (less planning due to available information)
  • Being supported in remembering routes
Assistive Technology

Sandy mostly uses a standard wheelchair. For longer distances or trips, Sandy uses an e-wheelchair because it saves power and is more comfortable. For short distances Sandy sometimes uses a forearm support.

Behavior
  • Planning several days or weeks in advance with photos, digital and printed maps and descriptions
  • Sandy finds ways inside unknown buildings with digital and printed maps, descriptions or by asking around
  • Sandy tries to remember known routes (e.g., back to the exit) in order to follow them independently
  • Uses building features for orientation or asks if possible
  • Uses navigation applications for outdoor environments and prefers visual instructions
  • prefers a safe and comfortable route to the destination and tries to understand the layout and structure of a building
  • If no information is available, Sandy tries to contact the building´s person in charge
Challenges
  • Remembering routes in unfamiliar buildings
  • Assessing the accessibility of buildings –> Missing Information about accessibility –> Uncertainty
  • Entering buildings that are not accessible (e.g., doors too narrow or heavy, no ramps, etc.)
  • Finding wheelchair accessible, safe routes in unfamiliar buildings
  • Buildings are not accessible with an e-wheelchair (too wide), even if buildings are marked as ” accessible “.
  • corridors that are very winding and have few right angles
  • lack of contact persons on site
  • Decision for suitable aid (e-wheelchair or standard wheelchair)
Useful features
  • Definition of an individual profile or specification of special characteristics for accessibility (e.g., door widths) /aids selection
  • Getting support in finding the way (depending on the assistive device): being able to choose a safe way through the building
  • Quickly getting in touch with an assisting person / porter
  • Entering and retrieving routes in buildings
  • Providing photos, printed or digital maps for on-site orientation
  • Highlighting safe areas in the building
