Cataract Simulation Goggles
Approximately 70% of people over the age of 60 suffer from cataracts, which cause clouding and gradual yellowing of vision. We collaborated with ophthalmologists to research elderly cataract patients and developed cataract goggles that let us experience the way they see. We use these goggles to validate and improve the legibility of catalogs, manuals, packaging, and product displays.
These goggles were implemented as standard product development procedure in 2000.

Voice Guidance Standards
Voice guidance is an effective method of conveying information for many people. We researched sound quality, volume, speed of speech, content, expressions, and length of sentence to create standards for voice guidance to make it easier to hear and understand.
These voice guidance standards were implemented in 2003.

Panasonic Universal Design Font Development (from 2006)
For optimal legibility of letters, we not only researched size and contrast of the letters, but the fonts themselves. Through global research, validation by senior users, and expert interviews, we identified four elements that constitute a good font: visibility, recognizability, legibility, and good design. We collaborated with a type foundry, Iwata Co., Ltd., and developed the world's first Universal Design font in 2006. This font is used for all operation panels on Panasonic products.
In 2008, the font was used as the brand logo for Panasonic Group.

Color Universal Design (from 2007)
In a collaboration with non-profit organization, CUDO (Color Universal Design Organization), we analyzed colors that can easily be distinguished by those with difficulties differentiating between red and green hues. The results are used on VIERA and DIGA's remote control color buttons and on program guides. We acquired the CUDO's Color Universal Design Certification, which is only given to products that have met their standards.
Color Universal Design was implemented in 2007.

Tactile Symbol Decals
The IH Cooktop electrostatic touch buttons are smooth and easy to clean, but they are hard to distinguish for visually challenged users. In order to ensure safety, we collaborated with Japan Lighthouse to develop tactile decals with embossed symbols which are easier to understand and more durable.

Research on Motion, Burden, and Mobility
Ease-of-use can be a vague and subjective sensation. To be more objective, factors such as users' balance shift and muscle stress were scientifically analyzed. We then visualized and quantified characteristics of movement and burden on the body, implementing the results into our product development.
Research relating to the movement and load in cleaning the toilet and bathroom
We have scientifically analyzed the obscure human "easy to use or uncomfortable to use" sensations by distribution of body pressure and pressure from grasping and distribution of body pressure to analyze how our products can best be used by our customers.

Pressure from grasping
Children's fingers often get caught in doors and hinges often. By developing finger-like equipment with sensors, we were able to test, validate, and develop preventive measures into various products.
