A Promise from a Son to his Elderly Parents

One day, to our great panic, my mother had gone missing suddenly, when she was almost 90 years old. Our family searched for her 3 days non-stop, every single one of the family members was looking for her anxiously.
We turned to public authorities, television stations and network resources, but there was no any news until the third day, that my elderly mother came home by herself with mud covering all over her, and she could not remember anything happened in these 3 days and had lost all of her belongings.
We were all just grateful that she came back home alive.
Not long after, my mother had gone missing again.
Just like the first time, we utilized all the resources we could, but very little information was returned.
The GPS tracking device we bought for her right after the first time incident, was disappointingly been disposed of on a random street.
We searched for her repeatedly, but with no direction left for us to track, the rescue opportunity seemed to disappear very soon. Just as we blindly searching for my mother, hundreds of miles away, there was a food booth, the owner of the booth noticed the appearance of this poor looking elderly lady is very similar to the photograph of the missing person announced by a network platform.
Soon communication was established, my mother was found and came home after curled a freezing cold night in a deserted place.
People can imagine my elderly mother's burning embarrassment when she was looking for her way home.
Hunger, cold, and sleeping outdoors, she was in such a desperate situation that she just lacked an intelligent tool to help her return home.

A Promise from a Grandson to his Elderly Grandparents

I am Yin Sheng (Walterz), the “son” mentioned in my father’s story and in the part of “Adaptive”, the above story is real an unforgettable memory of my father.
Here, I would like to express my deep gratitude to my grandma, for her painful experience opened the design process of this Atphon Travelwear. Unfortunately, my grandma no longer has the opportunity to try this achievement in person, but if she can know what we are doing today, she will feel relieved and satisfied, because I know my grandma very well, she has been "thinking of others" all her life, and moreover, she always cares more about others than about herself.
In those years when my grandma lost, I was studying for PhD in computer engineering at the University of British Columbia; like all of my family members, I too participated in the searches of my grandma in some missing events. The frustration I encountered during the searches was “real” but also “unreal”. I am a person works in the technology field for over 15 years, have access and knowledge to most modem technologies, and would never think tracking down a gone missing dementia person could be this challenging if I didn’t experience the entire process by myself.
During the searches, the most frequent question popping in my mind was “we have so much modern technology at our disposal, but so little was implemented in this sector, why didn’t we utilize more technologies at consumer-grade to help those in need?”
