Universal Design for Packaging in the Future

Introduction
The idea of universal design (UD) has rapidly spread for the past decade from the second half of the 1990s, and UD has become a general name that almost everyone knows. Especially in the packaging field, access-friendly UD products have increased.
UD dates back to 1985 when Ronald L. Mace disagreed with the barrier-free concept and advocated UD. The idea of UD was introduced to Japan in 1990. Aside from this trend, the E&C Project (the predecessor of the Accessible Design Foundation of Japan) advocated the concept of accessible design products in 1991.
The background for UD spreading and taking root in Japan in such a short period of time may be relevant to the population aging at a rate unprecedented in the world.
The aging society means a high proportion of elderly persons in the total population and a society where many households consist only of an elderly couple or older person who lives alone. This is also a society where the conventional sense of value is greatly changing.
Previously, younger and able-bodied persons were the larger population in society and were always the targets for product development. The needs of elderly persons or people with disabilities, who were minorities, were likely to be ignored.
An increase in the number of older persons means that these persons become a major force in the consumer market. If entrepreneurs do not provide products or services with a firm understanding of the needs of elderly persons and people with disabilities, they will not be able to survive the competition in our aging society.
In the process of UD spreading and taking root in society, a trend emerged where any product considered to be improved in usability, even if only slightly, passed as UD. Recently, however, UD has been developed by strictly confirming UD basics, a trend that means returning UD to the starting line.
In this paper, I intend to examine what UD will be sought after for packaging through confirming recent UD trends.
In the ISO and JIS standards for elderly persons, these persons are termed elderly persons and people with disabilities because people with disabilities can be considered as very characteristically representing the needs of the elderly. In this paper, I will examine problems of elderly persons and people with disabilities without distinguishing between them.

1. Trends of standards for elderly persons and people with disabilities
The ISO (International Organization for Standardization), which places high importance on the need to consider the problems of the worldwide advancement of our aging society and people with disabilities, published its policy statement "Consideration for the needs of older persons and people with disabilities in standardization work" in June 2000. The ISO also established ISO/IEC Guide 71 (Guidelines for standards developers to address the needs of older persons and persons with disabilities) in response to Japan's proposal in November 2001. Thus, the ISO has promoted developing standards for addressing the needs of elderly persons and people with disabilities.
JIS Z 8071 (Guidelines for standards developers to address the needs of older persons and persons with disabilities) was established as domestic standards corresponding to ISO/IEC Guide 71, and 27 JIS standards have been established based on JIS Z 8071 so far.
The aging of society is a trend in Japan and prevalent worldwide including developing countries (see Fig. 1). The term "Addressing the needs of elderly persons and people with disabilities" will be a keyword in every field of activity worldwide in the future.

2. Japan as the secretariat for TC122 (Packaging)
At present, the ISO has 229 Technical Committees (TC), and ISO member nations rotate the TC secretariats. The TC122 (Packaging) secretariat covers the main field of our packaging industry in Japan, and the Japan Packaging Institute (JPI) has been registered as a member of the National Mirror Committee for TC122.
In shop-floor (monozukuri) technologies for the 21st century when the population is aging worldwide, Japan, as the TC122 (Packaging) secretariat, is expected to promote the development of ISO standards for addressing the needs of elderly persons and people with disabilities through the field of packaging.
As one of these activities, the JPI proposed that JIS S 0021 (Guidelines for standards developers to address the needs of older persons and persons with disabilities) should be established as the ISO standards, and JIS S 0021 was officially registered for WG9* this January. Japan's strategy for developing standards started from the field of packaging toward the world stage.
*Name of TC122 working group registered with the ISO.
The proposed standards (JIS S 0021) will be deliberated in WG9. The JPI is supporting the WG9 by setting up a domestic committee for promoting international standardization: Investigation and International Promotion Committee for Standardization of Packaging for Addressing the Needs of Older Persons and Persons with Disabilities.
The JPI, as a head office, has been promoting the improvement of JIS standards. Two JIS standards were established in February 2007: JIS S 0022-3 (Guidelines for older persons and persons with disabilities - Packaging and receptacles - Tactile indication for identification) and JIS S 0022-4 (Guidelines for older persons and persons with disabilities - Packaging and receptacles -Usability evaluation methods).
The latter, JIS S 0022-4, is generally termed usability evaluation methods and is the very concept of the UD evaluation method.

3. UD and AD
In the above ISO/IEC Policy statement, the term UD is not used. Instead, "Accessible Designs which more widely cover human capabilities or their limits shall be introduced into the standards," is stated.
Accessible Design (AD) is a concept included in UD, and AD is defined as "Designs focused on people with some kind of functional disability and for the purpose of improving conventional designs to satisfy the needs of such people, maximizing the number of potential customers who can use the improved products, buildings, and services." UD is abstract in that it is an idea or a policy, while AD implies encouraging more activities, because it uses the word "accessible" which means ease of access.
ISO simply defines and uses AD as a design for addressing the needs of elderly persons and people with disabilities.
The root of UD can be traced to the concept of addressing the needs of elderly persons and people with disabilities. Both Mace and Kawauchi are in wheelchairs. Kawauchi explains, "Pursuing designs that can be commonly used by anyone, not just a particular group of people, leads to imagination for proactive design methods that cannot be fully expressed with the concept of conventional barrier-free design, and we call them universal designs." The concept of UD is that designs should accommodate the needs of older persons and persons with disabilities, but not exclusively focus on them.
Both UD and AD can be regarded as synonymous terms, but AD is used in ISO fields instead of UD, because AD is more suggestive of actuality.
Synonyms for UD include design for all, inclusive design, normalization, usability, and common use item.

4. Active seniors
Recently the number of energetic elderly persons has been increasing, and they are called active seniors. When people become older, it becomes difficult for them to do the same things they could do when young. Even if they are healthy or praised as active seniors, they cannot avoid gradual weakening from aging. Unlike when they were young, they cannot read small writing. They are faced by problems such as being hard of hearing, deteriorating memory, losing manual dexterity, and often stumbling over small steps. These are never morbid conditions, but just reduced physical ability and performance due to aging which almost all normal people suffer. As they age, responding to inconvenience becomes problematic.
If the number of people increases who have difficulty using a product that they have habitually used for many years, something needs to be improved for the product from the UD perspective. This warning must be addressed, or elderly persons and people with disabilities will sooner or later ignore the product.
The focus is if UD for packaging and receptacles of the future can attract elderly persons and people with disabilities, who have become the majority of the consumer market, as users, while expanding the usability of products that satisfy the needs of people whose physical functions have declined.

5. UD required for packaging
Retrospectively, I wonder if UD has been biased from pursuing convenience. If such UD can be called a UD that is deeper vertically, horizontally extended UD will be sought to attract the elderly persons and people with disabilities, whose physical function has declined, as users.
This does not mean that healthy people who were targets of conventional design should be patient for the convenience of elderly persons and people with disabilities.
In many cases, healthy people can also comfortably use the products for the comfortable use of elderly persons and people with disabilities. The basic principle of UD and AD is to make products used by as many people as possible with new information or innovation added to them without extra cost.
Usability of packaging and receptacles is comprehensively evaluated as a result of their going through every use environment and actual use from product purchase to separation and disposal. Even if a product is partly added to as a twist or improved but short of sufficient consideration for other parts, it will end up with poor usability. The product then cannot be considered as packaging and receptacles made considering many people including elderly persons and people with disabilities.

6. Development and evaluation of UD products are two sides of the same coin
Setting up a project team for UD so as not to miss the wave of aging society may be workable, but UD products cannot be easily created by such attempts alone.
UD should start with user dissatisfaction, particularly that of elderly persons and persons with disabilities. As mentioned above, the satisfaction or dissatisfaction with packaging and receptacles is evaluated as a result of their going through every use environment and actual use from product purchase to storage, opening and use. Therefore, UD products should be developed by firmly understanding the points qualified as UD.
Development and evaluation of UD products are two sides of the same coin. Developing UD products should be started from checking UD evaluation items.
For that purpose, I recommend utilizing "A list of usability evaluation items for packaging and receptacles" (see Table. 1) in JIS S 0022-4. This list consists of eight major classifications, and other medium size and minor classifications as individual deployment. Checking these classifications one by one will enable understanding what part of a product is inadequate and what type of product is required from the UD perspective.

7. List of evaluation items for packaging and receptacles (Standards)
For preparing UD evaluation items for packaging and receptacles, the evaluation items specific to packaging and receptacles were selected, and the elements related to packaging and receptacles were determined according to JIS Z 8071. Then these items were divided and listed as the following eight steps:
@ Purchase: product identification and portability
A Storage (storage prior to opening): storage methods and properties
B Opening: opening part, opening method, and openability (ease of opening)
C Use: retention, usage and usability
D Resealing: resealing method and ease of resealing
E Storage (storage after opening): storage method and properties
F Refuse segregation
G Disposal
Forms and purposes of packaging and receptacles are of great variety, but all these packaging and receptacles have a commonality among them from the perspective of UD evaluation items. Therefore, a list of usability evaluation items for packaging and receptacles (standards) was prepared with the expressions used in each evaluation item arranged to be comprehensive to apply to all packaging and receptacles.
First of all, preparation of evaluation items (a checklist of evaluation items) needs to be done in order to appropriately develop UD for packaging and receptacles before evaluation. As a starter, Table 1 is used with the expressions in its evaluation items being gradually replaced with expressions suitable for the characteristics, form, and use of the product to be evaluated.
Because Table 1 contains every item needed to evaluate UD for packaging and receptacles, improving evaluation items (a checklist of evaluation items) can easily and accurately be made by replacing the expressions already used in the evaluation items with expressions suitable for the product to be evaluated, thus making it possible to prevent necessary items being left out or expressions being biased.

Conclusion
The method for developing and evaluating UD for packaging and receptacles is detailed in JIS S 0022-4 which stipulates that the evaluation must be conducted by monitors including older persons and persons with disabilities of 20 percent or more. Only actual use of a product by elderly persons and persons with disabilities enables us to evaluate if the product has packaging or is a receptacle suitable for addressing the needs of many people including them. Moreover, UD extended horizontally, which is now being sought after, is envisaged.
Because horizontally extended UD is AD, I recommend using the term AD instead of UD in the field of practical business too, just like UD is being reworded as AD in standards. As the saying names and natures often agree goes, using the term AD to express horizontally extended UD will clearly transmit the concept of such UD for packaging and receptacles of the future, that is the same as AD, and AD will steadily spread among the general public.
Furthermore, as an effort related to educational campaigns responding to our aging society, an award for tactile indication for identification has been introduced this year into the Japan Packaging Contest, which is held by the JPI in June every year. Many UD products friendly to elderly persons and people with disabilities (AD products) are expected in the contest.
