Accessible Travel App

Challenge 04
Develop an app that provides information on accessible travel options for individuals with disabilities, including accessible accommodations, transportation, and attractions.

AccessAble Travel Guide is envisioned to be a comprehensive mobile application dedicated to empowering individuals with disabilities by providing them with detailed, reliable, and user-friendly information on accessible travel options. The app will serve as a one-stop resource for discovering accessible accommodations, transportation means, and attractions worldwide. By integrating user feedback, professional insights, and up-to-date accessibility data, the app aims to mitigate common travel challenges faced by people with disabilities and ensure a seamless travel experience.


Inadequate Filtering Options: Users often struggle to find travel options that cater specifically to their unique needs. Generic filters don't account for the wide range of disabilities, making the search process time-consuming and frustrating.

Lack of Detailed Information: Many travel apps provide limited details on accessibility features, leaving users unsure if a place meets their specific requirements, such as door width, ramp gradients, or tactile signage for the visually impaired.

Unreliable Reviews and Ratings: Reviews about accessibility are often buried under general comments, and the credibility of such reviews can be questionable as they may not come from individuals who actually require accessibility features.

Inconsistent User Experience: Users with disabilities may find it difficult to navigate the app if it's not designed with accessibility in mind, including features such as voice commands, screen reader compatibility, and alternative text for images.

Outdated Information: Accessibility features of a venue can change, but travel apps may not reflect those changes promptly, leading users to encounter unexpected barriers upon arrival.

Limited Coverage: Many apps focus on popular destinations, ignoring smaller towns or less touristy places that may still offer good accessibility but are not highlighted.


Deep-Dive Research: To ensure the app provides detailed and precise filters, designers should research the most common types of disabilities and the specific travel challenges associated with them. Engage with disability advocacy groups, and consult with accessibility experts to understand the breadth of features that should be included in the filtering options.

Leverage User-Generated Content: Encourage users to share detailed reviews focused solely on accessibility. Implement a verification system for reviews to ensure that they are provided by individuals who actually require the accessibility features, thus improving reliability.

Iterative Design and Testing: Adopt an inclusive design approach by involving users with disabilities in the design process from the beginning. Regularly update the app based on user feedback to ensure that navigation and content are accessible and intuitive for all users.


Discover: In this stage, you gather as much information as possible about the problem, asking questions and researching. You want to understand the problem from different perspectives and identify what needs to be solved.

Define: Once you have a good understanding of the problem, you narrow down your focus and define it clearly. You identify the specific aspects that need to be addressed and set goals for your solution.

Develop: Now, you start generating ideas and exploring different possibilities. You brainstorm, sketch, prototype, and experiment to come up with creative solutions. The goal is to generate a wide range of options without judging them.

Deliver: In this final stage of the first diamond, you select the best solution or a set of solutions based on evaluation and testing. You refine and develop your chosen solution further, considering feasibility, desirability, and viability.

After completing the first diamond, you move on to the second diamond, which represents the second half of the process. It focuses on implementation and bringing the chosen solution to life.

Deliver: This stage involves planning and organizing the resources needed to implement the solution effectively. You create a roadmap or an action plan to guide the execution.

Develop: Now, you actually start building or developing the solution. This may involve coding, designing, manufacturing, or any other necessary steps depending on the nature of the problem.

Define: Once the solution is developed, you evaluate and refine it. You make sure it meets the initial goals and requirements, and you address any issues or shortcomings.

Deploy: Finally, you launch or deploy the solution in the real world. You monitor its performance, gather feedback, and make any necessary adjustments or improvements.

The double-diamond framework emphasizes the importance of exploration and iteration. It helps you understand the problem deeply, generate diverse solutions, and ensure that the chosen solution is well-implemented and effective.
