Project Context
Machine Interface design for printers
Designed a user-friendly machine interface that
improves the usability of a domestic printer
The goal of the project was to design a new experience for human-machine interaction, particularly for home printers. By evaluating the usability of the printer interfaces, and understanding user behaviours and needs, the redesign process
By evaluating the usability of the current printer interfaces, the aim of the project was to redesign a user-friendly machine interface that addresses their evolving needs and significantly improves their productivity. This project entailed a comprehensive approach, incorporating insights from focused user interviews, extensive market research, and considerations of technical constraints of UI design for a machine interface.

Duration
10 weeks
Tinte originated as a collaborative project within an academic course. Subsequently, I seized the opportunity to refine the project by enhancing the interface design of the printer. The redesign process involved optimizing the printing task flow and enhancing human-machine interaction, particularly tailored for home printers. This project entailed a comprehensive approach, incorporating insights from focused user interviews, extensive market research, and considerations of technical constraints of UI design.

Market Research
By conducting online research we found what was available in the market and ranked them in priority of their popularity. We captured these by reading through customer reviews on e-commerce platforms like Amazon, eBay and Best buy. This helped us position market needs

Competitive Analysis

Understanding the market/ Market Evaluation
We started the project by understanding market trends and user's preferences for technology, price and features offered in current products. This helped set a foundation for further user research and final design.
Competitive Landscape
We discovered that Canon, Brother, Epson and HP were some of the popular brands and then compared features to evaluate user preference when choosing a printer.

User Research/ Evaluating the usability of printers
To understand the current usage pattern of printing at home, 30 focus interviews of mixed cohorts were conducted which further helped us map product usage journey and market trends.
User Interviews
How are printers used?
After the survey, we observed that most of the study tables in Indian homes do not have a space designed for the printer setup; which causes issues in accessibility. The user takes his laptop to the printer and connects it to print documents, or in some cases, users move the printer from room to room to connect it to the desktop.

This leads us to the problem statement...
How might we remove the dependency on a device to print, scan or copy documents and improve the experience of interacting with printers?
Task Flow
A simplified user task flow identifies the three main tasks of a printer and lists the activities for a user to accomplish the goal.
Scanning
Printing
Copying
Switch on the printer
Loads the document in the scanner
Download/ select the file to print
Loads the document in the scanner
Give a command to scan the document
Preview the scanned document
Choose how to share/save the file
Share/save the document file
Adjust the layout of the files to print
Select the printer properties
Give a command to print the file
Collect and check quality of printout
Switch off the printer
Wireframing
Based on the previous task flow, we listed the key features required for designing the UI screens. Using this list of the key features, we ideated on how these pages can be designed very comprehensively and neatly.

Since the components were designed for a machine interface, it was crucial to follow accessibility guidelines while choosing the font, color palette, and dimensions of the components to make the content readable, accessible and easy to navigate.

Learnings & Takeaways
One of the key learnings during this project was to reflect on the project at regular intervals. It helped us align the project with the goals.
While testing the interface designs, we learned the importance of digital accessibility and visual design. The context of use played a very crucial role in designing the solution and allowed us to view the importance of conducting a thorough ethnographic study while gathering user data.
Key archetype
While there were multiple members in a house who would use a printer, we identified the most frequent user and designed for one key archetype - the working student.

Sarah, a law student
About Sarah
Sarah is a law student working towards her master's. As a law student, she needs to constanltly print, scan and create copies of documents for the cases. She is always busy in her coursework and gets work done at the last minute.
Goals
-
Quickly scan, copy or print documents
-
Download or share scanned copies to other devices
Wants/ Expectations
-
Interconnectivity between devices
-
Eliminate the need for an external device to use the printer
-
Quick preview to avoid reprinting
-
Easy to understand controls and consistency with other devices

Challenges identified
Identifying the market gap and user needs/ What did the users want?
Set up
1.
-
Users found it very frustrating to connect their laptop, or mobile device to the printer in order to get the task done!
-
Almost 80% participants expressed connectivity issues that lead to incomplete task done
Functionality
2.
-
Controls - It was really difficult to understand the functions of the buttons on the interface, which led to the need to connect a familiar device like a laptop or mobile phone to perform tasks
-
Screen - The instructions mentioned on the screen were difficult to read and it was difficult to fix any error that occurred in the process
Usability
3.
-
Editing layouts of documents before printing was not possible on the small screen
-
Users often needed to share scanned documents or make edits to scanned documents before reprinting
-
All these pain points lead to the need to depend on a familiar device where it is easy to perform these tasks
Identifying the market gap and user needs/ What did the users want?
Pains
-
Has to connect a device to check layout and adjust printer quality settings
-
Cannot find how to recover from errors using buttons on the device
-
Finds the buttons difficult to understand at first
-
Smaller display screens do not show progress and updates
How did this help? How does this define the next steps
We identified two key personas who used the printers, that helped us to summarise the user research and clearly define user needs and pain points. These highlight the product market gap.
Initial hypotheses/ User needs identified
Connectivity issues
Customers reported challenges such as delayed responses and lags with bluetooth connectivity
Lengthy set up
Filler
Inconsistent interfaces
Filler
User needs identified
Customise orders
Customers wanted to customise orders that cater to their dietary preferences, even when placing an order with a group of people
Flexible payment method
With the availability of multiple payment methods, customers wanted the flexibility of choosing a method that allowed them to earn benefits and rewards.
Split bills
As everyone’s bill share differs due to their order customisations, customers wanted a way to split the bill in the app
Based on the user research, we found that users faced challenges in usability, connectivity and recovery from
Based on the user evaluation
Ideation
The redesigned solution solved the user journey by:
01
Reduced number of steps in task execution
02
Established a consistency in the control center
03
Quick preview before action improves error rates
04
Reduces dependency on other devices
Problem statement
How might we reduce the cognitive load associated with printers and make printing convenient for all groups without any third device linked to it?
