Aging boom, baby bust -- Some demographics of Taiwan

• Taiwan became an aged society in 2018,

and is expected to become a super aged

society by 2025.

• Age 65+: 15.28% (3.61M) @2019/12

• The average life expectancy in Taiwan

hit a new high of 80.7 years in 2018

• Life expectancy at age 65: men 18.44,

women 22.12 @ 2018

• Total fertility rate by World Population Review 2020

Macau: 1.347 (190/199),

Hong Kong: 1.326 (192/199)

Singapore: 1.260 (196/199)

Taiwan: 1.218 (199/199)

deaths, or almost zero natural population

growth in 2019

Average age of first time mother: 30.9

From research lab to community: More DESIGN THINKING!

• Empathy: User centered, persona, story

• Define the right problem: What, How, Why

• Think like a boss… (not like a professor…)

WhizTouch: IoT call button for

bedridden older adults

• Big button; mobile phone as receiver;

green light to confirm the call

• But…

• Internet usage is low for older adults

(31.1% /8.6%@2018). High monthly fee

for Internet service is not acceptable.

• Connecting the IoT product to home Wi-

Fi AP has been a major usability issue;

Wi-Fi coverage is often poor in bedroom

Narrow Band IoT: the last mile

• Sim card connects directly to NB-IoT base

station; used anywhere without setup

• NB-IoT based WhizConnect to bring smart

homecare products to the homes…

22

IoT care products at home?


Smart technologies happening in the homes (2015: IoT; 2017: NB-IoT; 2019: ML/AI)

• Consider B2B2C business model

Cloud AI:

The gerontechnology industry is not there, yet…

We are designers!

Design starts with a problem. Design ends with a

solution. Design s a problem solving process.

Find that Trigger－Caregivers are the best designers!

• UX: User Experience Design

From research lab to community

• Are we really doing the right

research which “will be useful in

the future?”

The future world needs trans-

disciplinary talents

• Are we educating students the right

way?
