Empathy tools are physical simulations and constraint-inducing artefacts that allow designers to experience, even imperfectly, the physical or perceptual limitations their users live with. Wearing gloves to simulate reduced dexterity, viewing a screen through a blurred lens to simulate low vision, or navigating a space in a wheelchair for a day — these experiences transfer visceral understanding to a design team in ways that no amount of data can replicate. They build the kind of embodied empathy that leads to genuinely inclusive design.
What It Is
Empathy tools include ageing simulation suits that add weight, joint restriction, and sensory impairment, vision simulation glasses that replicate conditions like cataracts or glaucoma, hearing impairment simulators, and constraint-inducing gloves or splints. They are used both for internal design team education and as provocations in stakeholder workshops to shift perspective and generate design insights that would otherwise remain abstract.
How to Run It
- Select the constraint most relevant to your user group — sensory, motor, cognitive, or environmental.
- Obtain or construct appropriate simulation tools; commercial simulation kits are available for many conditions.
- Ask participants to complete a realistic task using your product or service while wearing the simulation tool.
- Capture observations, emotional reactions, and specific moments of friction during the task.
- Debrief immediately: what was most surprising? What would you change?
- Use insights to generate design criteria and HMW questions for the next design phase.
Five minutes in a simulation suit produces more empathy for a user's daily experience than five hours of reading a research report.
When to Use It
Empathy tools are most valuable during early project scoping, stakeholder education, and team onboarding. They are particularly effective in accessibility design, inclusive design for older adults, and any project where the design team's baseline experience diverges significantly from the target user's. Use them to complement — not replace — direct user research.
Tips for Success
- Be explicit about the limitations of simulation: it is a provocation, not a faithful representation of a lived experience.
- Always follow simulation with real conversations with the people who actually live with the constraint.
- Focus simulation tasks on the most critical flows in your product, not generic activities.
- Document the specific friction moments that arise during simulation as candidate design problems to investigate.
