Motion capture records a user’s movements so designers can analyse physical interaction with a product, while haptic technology creates simulated touch or force feedback. Both support prototyping by helping designers test ergonomics, usability, and user experience before producing a final solution.
How the technologies support prototyping
Motion capture uses sensors, cameras, or wearable markers to track the position and movement of the body. The captured data can be transferred to a digital human model, allowing designers to identify restricted movement, excessive reaching, poor posture, or repetitive strain.
For example, when developing a vehicle interior, a designer could record users reaching for dashboard controls. If shorter users must lean forward or rotate their shoulders excessively, the controls can be repositioned in the next prototype iteration.
Haptic technology uses actuators or force-feedback devices to reproduce sensations such as vibration, resistance, pressure, or texture. It allows users to experience how a digital or partially developed product might respond, even when a complete physical prototype does not yet exist.
| Technology | Main design use | Example |
|---|---|---|
| Motion capture | Records and analyses user movement | Evaluating posture when using a workstation |
| Haptic technology | Simulates tactile or force feedback | Testing the vibration response of a virtual control interface |
| Used together | Evaluates physical interaction and sensory feedback | Testing movement and control resistance in a virtual vehicle cockpit |
These technologies improve iterative design because testing produces data and user feedback that inform modifications. They may reduce the time, material use, and cost associated with repeatedly manufacturing high-fidelity physical prototypes.
A common misconception is that motion capture and haptic technology are only used in gaming. In design technology, they are also important tools for user-centred ergonomic analysis, virtual prototyping, and interface testing.
Exam technique
For A2.2 Prototyping techniques, distinguish the two technologies clearly: motion capture collects movement data, whereas haptic technology provides sensory feedback. In an explain question, identify the technology, describe its mechanism, and link it to prototype testing, user needs, and design refinement.
