Linkage is an aid that makes life easier for the senior citizens and their families. Linkage is an elderly monitoring ecosystem. This iF award winning design consists of a wearable device for senior citizens, and a mobile app for their family. The wearable monitors pulse rate, offers reminders to the elderly user, and sends emergency alerts to their family. It also connects the elderly user with their family over voice messages and calls. 

With these key features, the device lets the elderly and family members enjoy their independence and private space, while assuring immediate help in the hour our of need.

The challenge

In today’s world retired senior citizen’s lack the attention and warmth of their loved ones. These personas are not completely bed ridden or diseased, but are active old people who constantly feel the need to be connected to their family members and be socially active. So challenge was to designing a communication system that can support both the criteria.

User Research

Our first task was to know the facts and figures about elderly community. 


8.5 % of people worldwide (6.17 million) are aged 65 and over

In the US, nearly 29% of the 46 million community - dwelling older adults live alone

In the US, 10.3% of people of different age groups live alone

Health insurer Cigna's 2018 U.S loneliness index found that 47% or almost half of Americans report feeling lonely

Shadowing and User interviews

We spoke to elderly people and their families. Here are few insights from the interviews that validated our assumptions and helped us understand the user. The first 3 are the elderly personas and the next 3 are the family members of the elderly.

System Diagram Based on Research Insights

Interacting with users and empathizing with them helped us in formulating our linkage system diagram. We defined that the elderly would need an efficient less tech savvy device and the family members would need a mobile app which has device compatible features which can be quickly accessed. We strived to solve some of the problems mentioned in the above user quotes

Key Interactions

addressing the most prominent user activities on the mobile app

Wearable Device

The wearable device has a wrist strap, microUSB charging port, 3.5mm audio port, and an emergency alert button which immediately notifies family members and caregivers with a single press. Additionally, it has a fall detection feature which automatically detects the fall and notifies the family members and caregivers. The wearable continuously monitors the pulse rate. Mobile app receives hourly summary of the pulse rate, and also receives  alert when the pulse rate is outside the normal range.

Mobile App + Wearable Device

The upcoming reminders, alerts, messages on the dashboard of the app show up on the wearable screen as transient reminders. The reminders set on the mobile app show up on the wearable as audio visual notifications. The family members and elderly can chat using the messages feature. Messages sent from the mobile app can be heard or read on the wearable. Audio reply can be sent from the wearable.

The wearable can be pinned to clothing, attached to a walking stick wheelchair or can be worn on the hand. It has an elastic strap and a simple magnetic attachment mechanism.
