Suggest techniques which can be adopted to impart Computer Education for (i) Visually impaired students (someone who cannot write). (ii) Speech impaired students (someone who cannot speak).

Question

Accepted Answer

> [!TLDR]
> Computer education for differently-abled students relies on **assistive technology** matched to their specific limitation — audio/voice-based tools that don't require writing for visually impaired students, and text/visual-based tools that don't require speaking for speech-impaired students.

**(i) Visually impaired students (cannot write)**
Since the student cannot see the screen well enough to write/type accurately in the usual way, the aim is to replace visual writing tasks with **audio and voice-based interaction**:
- **Screen reader software** (e.g., JAWS, NVDA) that converts on-screen text into speech, letting the student hear menus, documents, and messages instead of reading them.
- **Voice recognition / voice typing software**, so the student can dictate their answers or commands verbally instead of typing/writing them.
- **Braille keyboards and Braille displays**, which let the student input and read output using the Braille tactile system.
- Audio-based learning material (recorded lectures, text-to-speech textbooks).

**(ii) Speech-impaired students (cannot speak)**
Since the student cannot communicate verbally, the aim is to replace voice-based interaction with **text and visual-based tools**:
- **Text-based communication tools** — typing on a keyboard, on-screen keyboards, or touch-based input to communicate instead of speaking. …
