SizeChina

SizeChina is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand SizeChina rather than just read about it. In short: SizeChina is a 3D anthropometric research project at the School of Design at the Hong Kong Polytechnic University. It is also referred to as SizeChina.com.

Key takeaways

SizeChina belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect SizeChina to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of SizeChina from memory before moving on to harder problems.

Reference excerpt

SizeChina is a 3D anthropometric research project at the School of Design at the Hong Kong Polytechnic University. It is also referred to as SizeChina.com. The purpose of the research project is to "create the first-ever digital database of Chinese head and face shapes". It was created in response to the lack of information about Chinese head sizes and shapes, and the fact that most products designed for the head or face are based on Western face shapes. It contains over 1.3 billion faces. The results from the SizeChina project are invaluable to industries such as medical, optical, entertainment and sports, all those concerned with headgear such as sunglasses, helmets, sanitary face masks, etc. As this database, and the models created from it, provides information on Chinese features, the market will start creating the first China fit products. The first product designed using the SizeChina data, a military/police goggle, has been commercialized. The database is compiled of data from digital scanning equipment based on people from six different regions in the People's Republic of China; Guangzhou, Hangzhou, Lanzhou, Chongqing, Beijing, and Shenyang. The Director of this project is Dr.Roger Ball, an accomplished Industrial Designer and Design Professor. He won the 2009 Presidents Award for Research at The Hong Kong Polytechnic University

Awards SizeChina won four major international design awards in 2008: IDEA/BusinessWeek Gold Medal - Research Category, IDEA/BusinessWeek - Best in Show (co-winner with Apple iPhone), Fortune Magazine(China)- China's Most Successful Design Award, Design For Asia Award - Grand Prize. In 2009 SizeChina won the Red Dot Design Award and was a Finalist for the Index: Award - Design to Improve Life. SizeChina data products were commercialized starting in October 2008 by Hong Kong-based www.certiform.org.

Worked examples

Example 1 — a first encounter with SizeChina

Start with the simplest possible case. Write down what SizeChina claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to SizeChina before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about SizeChina ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of SizeChina

In research: SizeChina appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses SizeChina in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: SizeChina is common in secondary-school and first-year university syllabi. It links to neighbouring topics Anthropometry, so understanding it makes those chapters shorter.
In everyday life: Look for SizeChina outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is SizeChina in simple terms?

SizeChina is a 3D anthropometric research project at the School of Design at the Hong Kong Polytechnic University. It is also referred to as SizeChina.com.

Why does SizeChina matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study SizeChina?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
