Idea & Goal

Main Concept

• Connect a fjtness rowing machine with Virtual Reality for „Exergaming“
• Make it possible to steer the virtual boat similar to a real one
• Create a virtual world that allows for specialized training sessions

and is fun to train

• Modify the rowing machine to create an input for PC‘s

Goal

• Make it fun to train and improve yourself
• Make users prefer longer training sessions
• Encourage the users to train in the right manner

Input Interpretion

Input Output

Speed x & y per Frame with high variations

• 1.X

1.X add Speed up to get the arms Position and clamp to a safe range of arm movement and recalibrate itself

• 20%

120% 0% 100% Smooth PPM signal to avoid jumps

Interaction Methods

Pulling arms back pushes rudder into the water and creates thrust Pushing arms forward pulls the rudder out of the water to avoid braking Pulling arms irregular creates rotational thrust Pulling the arms in a regular, constant speed creates the most thrust Oculus Rift tracks your heads position in a realistic style

Application

Application

Exergaming

• pulling with too much force make you move slower

=> avoid damaging your spine & back

• every ~100m is a „magic vortex“ pulling back with force

=> high training efgect

• rotation impule keeps on spinning the boat

=> avoid one sided training

Virtual World

• every start generates a new world based on randomized algorithms

=> repeating sessions doesn‘t get boring

• close trees, particles and depth objects under water

=> make a strong stereoscopic VR efgect

• small fjshes swarming around that you can pick up

=> rewarding efgect while training

Virtual Reality First Feedback

Pro

• distraction from time results in longer training sessions
• 50% prefer training with VR
• movement, training & efgectiveness easily trackable
• having fun makes training attractive

Con

• no benefjt in direct muscle training
• 50% prefer training without VR
• 4/5 sufger from dizziness
• extra weight
• extra costs
