This short film, first published in 2015, is for teachers and review is recommended before use in class.
Professor Danielle George demonstrates how haptic technology lets you feel things that aren’t really there.
With the help of its inventor, Professor Sarah Baillie from the University of Bristol, she learns about the “haptic cow,” a teaching device for training vets how to feel if a cow is pregnant.
The haptic device clips onto her finger and restricts her hand movement, tricking her mind into believing that she is touching a solid object, when in fact it is the pressure from the haptic finger clip that is causing this sensation.
This is how the current generation of haptic technology works.
This clip is from The Royal Institute Christmas Lectures 2014.
Teacher Notes
Key Stage 3
Introduction:
Explain what a virtual object is and why, normally, we can’t touch virtual objects.
Video questions for pupils:
1. How do haptics help trainee vets?
2. How did the user make use of a feedback loop? (She adjusted the pressure she applied when the haptic cow ‘mooed’).
Activities:
- Start a discussion on haptic technology, and how it allows you feel things that aren’t really there.
- Ask, how could haptics be used in medicine to help people recover from operations more quickly?
- How could haptics be used to make computer games more realistic?

Additional material:
- Think of three scenarios where haptic technology could allow users to be trained using virtual technology.
