Design an alarm clock for blind people.

Focus on understanding the unique needs and challenges faced by blind users when interacting with an alarm clock. Consider tactile elements, such as buttons or dials, that can be easily differentiated by touch. Think about auditory features, like voice prompts or customizable sounds, that enhance usability. Additionally, explore how the device can integrate with existing technologies, such as smart home systems or mobile apps, to provide a seamless experience. Finally, address accessibility in terms of setup and functionality, ensuring the design is intuitive and user-friendly for individuals with varying levels of familiarity with technology.
