GOAL

Our goal is to enhance the "Uncompromising Geek" experience by redesigning the "schedule" feature of the Google Nest Thermostat. We aim to deliver a high-end, innovative interface that blends cutting-edge functionality with a sleek, visually appealing style.

RESEARCH & DEFINE

Current Thermostat & App Analysis

Moblie App
existing research 1

The app's page design is simple and not visually “high-end” enough.

The whole process of setting up a shedule is confusing and an inconsistent experience

current app flow 1

The schedule function can only be used to adjust the temperature and time with your fingers, and it is not possible to adjust the temperature precisely.

The process is too complicated, causing psychological pressure and a high cognitive load for users

The schedule page makes it hard to know where to exit and return

The schedule setting is done in a point-based manner, making it impossible to set an accurate time span, and the information is unclear.

problem statement

​The Nest Thermostat's physical interface and mobile app lack consistency in interaction logic and visual experience, making it challenging for users to switch seamlessly between platforms.

 

High-tech users expect a more intuitive, aesthetically pleasing, and smooth experience. Enhancing interface design, improving consistency, and incorporating a more futuristic feel are essential to increasing user satisfaction and loyalty.

How might we?

  • How might we streamline the Nest Thermostat’s interaction flow to ensure a more intuitive and user-friendly experience across all touchpoints?

  • How might we optimize the visual design and interactive elements to deliver a premium user experience that meets the needs of tech-savvy users?

  • How might we enhance connectivity between the Nest Thermostat and mobile app to ensure seamless integration and effortless control in a smart home ecosystem?

The positions of "Confirm" and "Back" are not fixed, and the length of the items changes over time, which can lead to situations where they extend beyond the page and become difficult to control.

In the "Edit an item" state, the length of the item is fixed, while the time changes as it rotates, causing the left-side timeline to shrink.

The positions of "Back" and "Confirm" are fixed, preventing confusion during the editing and adjustment processes.

The "Selected" and "Edit" states are not clear enough, making it easy to become overwhelmed.

The visual and functional representations are clearer, reducing user effort.

edit temperature

The temperature adjustment bar confuses users, making it difficult to maintain consistency.

There is too much information on the page, yet it still lacks the option to activate "eco" mode.

The time adjustment is also limited.

Separate the time adjustment and temperature adjustment settings. Ensure consistency between the functionality and visuals with the embedded thermostat.

Add options to activate "eco" and "fan" modes.

Make temperature adjustments more precise using finger gestures.

The interface should be clear, preventing user confusion.

FINAL DESIGN

MOODBOARD &
VISUAL CONCPT

"HIGH-END & INNOVATIVE"

Our team members each collected at least 60 visual elements and images that aligned with the theme of "High-End & Innovative." Ultimately, we voted on 400 images to select the most representative ones, which formed our project moodboard.

This process not only sparked our creativity but also ensured that the moodboard reflects our shared vision and design direction.

​Key Learnings
Simplifying Design for Unique Physical Interaction

Through redesigning Google Nest, I gained invaluable experience in adapting to the product's unique physical interaction constraints. The small screen size and limited resolution challenged me to prioritize clear and concise information, focusing on essential elements to ensure usability.

Designing for a High-End Brand Identity

I learned to align UI design with brand positioning, focusing on Nest’s premium status through elegant typography, colors, and materials. This enhanced my ability to balance functionality with brand identity, creating visually appealing, user-centric interfaces.

Enhancing Usability by Streamlining UI and Interaction

By refining the UI and interaction processes, I learned how to eliminate unnecessary pages and reduce cognitive load. This experience reinforced the importance of simplicity and efficiency, ensuring users can interact with the product seamlessly while enhancing overall usability.

Embracing Failure as a Path to Innovation

Failure and feedback are essential drivers of innovation in UX design. Embracing iterative processes allows teams to view setbacks as valuable learning opportunities, leading to more user-centered solutions. By fostering a culture that openly shares failures, teams can continuously grow, adapt, and create better experiences.
