Ligo

A smartwatch application for older adults to get help in emergency situations.

This project was part of a challenge to demonstrate advantages smartwatches have over smartphones. Our team of two (Cheers, Karen Mozzaquatro!) decided it should have a social impact, too.

Ligo helps older adults and, by extension, any person that needs some kind of assistance in their daily lives.

We interviewed different stakeholders: possible users, family members, nurses and other caretakers.

The research lead us to three personas.

People often hold a negative view towards assistive technology, and can be reluctant to adopt technology that is clearly designed to compensate for functional loss. Writing use scenarios and requirements based on our interviews, and then considering the users' skills and behaviors was essential to define the interaction framework.

Interaction framework for Ligo

The screens below were designed to be printed and precisely cut to simulate an Apple Watch. We performed a quick concept test of the help button function and our main menu.

Medium-fidelity paper prototype

A high-fidelity prototype was developed for a usability test to analyze how older adults interact with a real smartwatch and with our application.

The high-fidelity in action.

Findings
  • It is difficult for older adults to differentiate touch and forced touch.


  • The participants were not familiarized with the snooze function concept in alarms.


  • It is important to consider the amount of time before a product screen goes off, as older people may need longer to interact and plan their next action.


  • Inserting assistive technology into devices already adopted by the general population will surely increase its acceptance.
