RESUMEN

Tari is an app and web that has the objective of helping older adults living alone with daily chores, such as buying food, organizing and consulting medicines, and other common tasks through a system of volunteers. The idea and name of the project were inspired by my grandmother who is in this situation.

 

The app allows older adults to submit a request for help with a specific activity; volunteers see requests in the area they are in and have the opportunity to help with the task.

The website is aimed to other adult users who want to help older adults, for example, family members, without violating their independence by providing information through the account synchronization function, enabling the addition of a payment method so that the older adult does not have to take care of it, doing daily tasks when they can and knowing what medicines they need to take.

PROBLEM

Older adults who live alone often need help with simple daily tasks, such as grocery shopping, keeping track of medications, household chores, etc.

GOALS

The goals are to help older adults when they are in a situation that needs help and to provide other adults who want to help the elderly with a way without violating their independence.

Investigation

PRIMARY USER

Katy is a senior living alone and needs a way to buy groceries that are delivered directly to her home because it is difficult for her to carry groceries to and from the store alone.

SECONDARY USER

Rosa is an adult, Katy's daughter, and she needs to find a way to help her mother without violating her independence because she knows the problems she has in her day-to-day life but cannot help her with all of them.

I conducted interviews and created empathy maps to understand the users I'm designing for and their needs. A primary user group identified through research is older adults who live alone and need help with daily tasks.

 

In particular, users agreed that the main task they need help with is shopping, as they have trouble going to and from a market. This group of users, through research, also revealed their need to keep track of the medications they take, specifically remembering what each one is for and when would be an approximate date to get a new box.

The main pain points that the app addresses are:

SHOPPING

Users have problems transporting their shop from the market to their homes, and they also feel insecure doing so.

DAILY TASKS

Users need help with simple and specific daily tasks that they cannot perform due to physical limitations.

MEDICINE

In the case of taking multiple medications, users often forget if they took it when they should, why they take it, and when the box is finished.

Design process: Tari app

INFORMATION ARCHITECTURE

Based on the investigation of the needs of the users, also counting on the contribution of the users through card sorting, I arrive at the following information architecture for the app.

USER FLOW

I built a user flow of what the journey looks like from start to finish in each section of the app. Being a design for older adults, with the usability tests, they needed to have confirmation after each step, as well as having the possibility of canceling at any point.

This user flow helps to understand how they can interact with the product, as well as visualize the navigation through the user's goals.

PAPER WIREFRAMES

The goal is to create a simple and concrete path, with the least amount of options that the user must follow when using the application. When dealing with older adults as the primary user, it is a priority to maintain a path to follow that avoids overwhelming them.

DIGITAL WIREFRAMES

The goal of the digital wireframes was to test an earlier version of the app. Easy navigation was the main component users needed to see in the design, with as few options as possible to follow to avoid confusion for older adults using the app.

Upon entering the app, the user is presented with this screen, where they have three options: shop, medicine, or help with tasks, with a brief description of what is in each section.

In each section, the screen works similarly: title, description, and action to follow.

LOW FIDELITY PROTOTYPE

Here you can find the lo-fi prototype.

USABILITY TEST

I performed two rounds of usability studies. Findings from the first study helped guide designs from wireframes to mockups; the second study was through a high-fidelity prototype and revealed what aspects of the mockups needed refinement.

ROUND #1

1. Users need another way to document information without relying on the phone keyboard.

2. Users want to make tracking the medicine they take optional.

ROUND #2

1.  Users would like to receive instructions on how to use the app when they open it and have the option to see them again when they need to.

SHOPPING

In the first section, "Shopping", is where the user can send a shopping list to be bought and taken home by volunteers; the list can be typed with the keyboard of the phone, narrated in a voice note, or taken with a photo of a list written on paper. Once the list is made, the volunteer chooses the items, confirms with the user, makes the payment with the user's Tari account, and takes the shop to the older adult's house.

Tari allows the purchase to be paid at the moment with the account linked to the market or at the end of the month with all the purchases made, this is left to the user's choice when configuring the account

MEDICINE

In this section of the app, the user can keep medication monitoring. The actions they can take are:

  • Enter medication and track their intake through notifications.

  • Know what each medication is for.

  • Look-up for leaflet inserts for some medications.

HELP WITH TASKS

Finally, this section was created so that the elderly can ask for help with simple daily tasks that they cannot perform due to any limitations. Like the shopping system, the user enters or chooses the task they need help with and volunteers come to do it.

Again, here you can write down the task with the keyboard of the cell phone, describe it with a voice note and/or take a photo in case you think it is necessary.

Design process: Tari web

INFORMATION ARCHITECTURE

With the app design complete, I started working on the responsive website design. I used a sitemap to guide the layout structure of each screen, considering that the website would be used primarily for information associated with the application.

USER FLOW

I built a user flow of what the journey looks like from start to finish in each section of Tari's website. Since the goal of the product is to provide information, there is no single path for the user to follow.

RESPONSIVE WEB DESIGN

Designs would include mobile devices, tablets, and desktop computers. The design would be optimized to adapt to the specific needs of the user of each device and screen size.

Final design

STYLE GUIDE

Tari's identity is based on the idea of having an app that is minimalist and with contrasting colors, taking into account that it would be used by older adults without overstimulating with information.

HIGH-FIDELITY PROTOTYPE: TARI APP

ACCESSIBILITY CONSIDERATIONS

1

Clear labels for interactive elements that can be read by screen readers.

2

The design in each section of the app has a similar structure, allowing one or two possible paths to follow so that older adult users don't get confused.

3

I used minimal iconography to help all users have a better understanding of the design.

5
Conclusions

IMPACT

I hope this design has a positive impact in the real world, helping older adults in need and creating a community where collaboration is the main goal.

LEARNING

Designing an app for seniors was surprisingly challenging. Being from a generation that grew up with technology, putting myself in a position to design an interface for a generation that doesn't know this language took a lot of trial and error, which reaffirmed my position that it is essential to include the user in the entire design process.

IN THE FUTURE...

Due to time constraints, I could not carry out the specific responsive design for Tari's website, so in the future, it would be the priority. The next step would be to run another round of usability testing with a larger group of older adult users to see if any other changes should be made to the app.
