Match the following devices with their corresponding descriptions.

Devices

1. Haptic Gloves

2. Tactile Display

3. Voice Response Unit (VRU)

4. Data Glove

Statements

i. Generates tactile sensations and may sense user interaction.

ii. Captures fine hand/finger movements for computer input.

1. A. 1-ii, 2-i, 3-iv, 4-iii
2. B. 1-ii, 2-iv, 3-i, 4-iii
3. C. 1-iii, 2-iv, 3-i, 4-ii
4. D. 1-iii, 2-i, 3-iv, 4-ii (Correct answer)

Correct Answer

Option D — D

Detailed Solution & Explanation

The correct answer is Option D.

Key Points

• Haptic Gloves (1) → iii: detect user gestures and provide force feedback.
• Tactile Display (2) → i: generates tactile sensations and may sense user interaction.
• Voice Response Unit / VRU (3) → iv: generates synthesised audio output for interaction (as in phone IVR systems).
• Data Glove (4) → ii: captures fine hand/finger movements as computer input.

Exam Tip

• the discriminator is force feedback (gloves that push back) vs plain tactile sensation (a display surface), and audio output (VRU) vs motion capture (data glove).
• These are common Human-Computer Interaction (HCI) devices.

Additional Information

• Haptic technology conveys information through touch — force feedback, vibration or resistance — and underpins VR gloves, game-controller rumble and surgical robots.
• A tactile display renders shapes or text for touch, the best-known example being a refreshable Braille display.
• A Voice Response Unit belongs to the audio-output family, alongside text-to-speech engines and IVR phone menus.
