How did it come to this?
The Haptic Cow
Background Veterinary Surgeon
1986
2006
• Mixed Practice • Farm Animal
• Specialising in Cattle Health and Production (1992)
• Small Animal• Soft tissue surgery• Developing the business & improving
services
Background (1) Veterinary Surgeon
• Masters in Information Technology (2001-03)• 10 Modules (from OOP to Databases)• Developed the Haptic Cow
• PhD in Computing Science (2003-06)• Validated the Haptic Cow
Background (2) Computing Scientist
2001 2006
Background (3) Teacher & Educational
Researcher
Vet + computing scientist + teacher:• Haptic simulators and haptic computer
games• Work-based learning• Business skills, female entrepreneurship• Interprofessional education• Web 2.0
2006 Move to join

What is Haptics?
• adj. [Greek haptein, to touch + ic] OED
• Haptic Simulators allow you to:• Feel 3D virtual objects
• Uses: • Visually impaired computer users• Veterinary and medical training
It’s an ideal technology for teaching examinations that depend on palpation
The PHANTOM (SensAble
Technologies)
The Haptic Cow
Can’t see what’s going on…
Could I find a better way to teach this?
(for pregnancy diagnosis and fertility examinations)
• Created 3D virtual models of the bovine reproductive tract (cervix, uterus and ovaries) inside the bony pelvis and abdomen
First the C++ code is written… then… the anatomical model is palpated
many, many
iterations5 years...
The Haptic CowDesign
The Haptic Cowis born
“It’s cool”
The instructor provides guidance while following the trainee’s progress inside the virtual cow on the computer screen
The student palpates the virtual bovine reproductive tract and receives touch feedback from the PHANTOM haptic (touch feedback) device
“Awesome”
Research has shown: - It is reasonable life-(cow)-like - Students perform better when examining real cows - It’s now used in 4 of 7 UK vet schools
Inside fibreglass cow is a PHANToM haptic
device
Computer software (written in C++)
Technology Making a Difference
Using Haptic Cow @ RVC
1. Anatomy in 1st year 1
2. 3rd years basic skills for examining 1st real cow
a) Peer assisted learning (PAL) – student tutors 2
b) Let the computer do the teaching! 3
3. Role-play in clinical rotations 4Over 2,000 ‘sign ins’ @ RVC since Feb 2007 & more than
10,000 members of the public have tried our haptic simulators

Learning Anatomy
Kinnison, Forrest, Frean & Baillie (2009). Teaching Bovine Abdominal Anatomy: Use of a Haptic Simulator. Anatomical Sciences Education , 2(6): 280-285
Truly 3D, no cadavers & no mess
• Compared performance of a group of students trained with simulator with a control group• Both groups set task of finding uterus in cows• Simulator trained group significantly better
(p<0.05)
• Then did an ‘ease of use’ study• 61 students piloted it ‘free access’, positive
feedback
Does it work?

Contextualised Simulation
1. History2. Palpate
3. Diagnose (& treat)
Very popular with students
We have simulations of other species
including human
As it is a Computer...
• It can be more than the Haptic Cow• I.e. as it’s software it can become many cows & other species...
