The Challenge

1. Low web accessibility for the disabled
2. The limitations of TTS(Text to Speech) function
3. Unkind transportation apps to people who are blind
4. 3rd party assistance is required when using public transportation

The Outcome

1. It provides a contrasting color, readable text size, noticeable visual image, vibration pattern, and voice notification to increase accessibility for apps.
2. It provides an overall solution for users to take a bus. Finding the bus stop, finding the right bus, getting on the bus, and getting off from the bus.

Problems

Limit of TTS function

Limit of TTS function

Although TTS(Text to Speech) function for people who are blind has been introduced to Smartphones, there are no alternative characters that can be converted to voice. Also, there is no auditory or tactile assistance available in apps. Thus, reducing accessibility to apps for people who are blind.

Need other person's assistance while using public transportation

Uncomfortable with the smart device screen

Since display screens of smart devices are designed mainly for people with normal vision, it is difficult for most people with low vision to use them properly.

Need other person's assistance while using public transportation

Need other person's assistance while using public transportation

Blind people find it difficult to recognize where they are and where they are going. Long-distance travel requires continued assistance from a third party. It is difficult to make subjective movements.

Lack of public transportation app for blind people

Lack of public transportation app for blind people

According to Sookmyung Women's University's Web Development Institute, 10 out of 12 existing public transportation applications were considered to be very insufficient for people who are blind. The development of public transportation applications is not enough for blind people.

Inconvenience the use of buses

Inconvenience the use of buses

While the blind people relatively satisfied with the subway system due to its high convenience and guaranteed regularity, the blind people complained about the bus system because of its safety, such as frequent stops. Therefore, it was necessary to make a bus application for blind people to give them a general chance to use the bus.


Interview

Affinity Diagram

Affinity Diagram

Interviews and user tests were conducted for 13 people (two blind people and eleven people with low vision). In addition, we did interviews with social welfare service providers and other related people to users.
