Explanation of Solution
Types of assistive technologies for input:
- A keyboard with larger keys: A limited hand mobility users can use an on-screen keyboard or a keyboard with larger keys.
- Head-mounted pointer and switch: A user with limited hand movement can use a head-mounted pointer to control the pointer or insertion point. They can use switches, which is an alternate option of a mouse button. The switch might be a foot pedal or hand pad that controls the pointer...

Question3: (30 MARKS) Passenger Rail Agency for South Africa Train Scheduling System Problem Statement Design and implement a train scheduling system for Prasa railway network. The system should handle the following functionalities: 1. Scheduling trains: Allow the addition of train schedules, ensuring that no two trains use the same platform at the same time at any station. 2. Dynamic updates: Enable adding new train schedules and canceling existing ones. 3. Real-time simulation: Use multithreading to simulate the operation of trains (e.g., arriving, departing). 4. Data management: Use ArrayList to manage train schedules and platform assignments. Requirements 1. Add Train Schedule, Cancel Scheduled Train, View Train Schedules and Platform Management 2. Concurrency Handling with Multithreading i.e Use threads to simulate train operations,…
