The case study on Automatic Ticket Vending Machines (ATVMs) highlights significant user experience issues, such as lack of initial guidance, confusing interfaces, and readability problems in bright conditions. Suggestions for improvement include simplifying screens to display one action at a time, providing clear navigational cues, and enhancing user training and support at railway stations. Both designers and railway authorities are encouraged to take steps to make ATVMs more user-friendly.

 More undo or back buttons for better navigation
 Cues at every screen to help the doing the task and navigation.
 For users
 The user has to approach the railway customer care for
sufficient understanding and training to use ATVMs.
 Railway authorities should also serve the customers who are in
need with instructions to use and demos at multiple counters.
