The Opportunity
Recognizing that current keyboard options fail to meet the needs of users with limited mobility or non-verbal needs, this keyboard was purpose-designed to provide a communication method and simplify the setup required when using adaptive switches.
My Approach
Beyond its function, I designed for sensory comfort, and customizable components that adapt the keyboard to every user's unique sensory needs. For this, I devised a set of must-meet design requirements based on thorough market and user research.
The Results
Developed a portable mechanical keyboard designed to restore user autonomy by providing an alternative way to communicate. Streamlined the user experience by embedding an integrated switch interface, simplifying required gear when using adaptive switches.
Adaptive Technology is crucial for helping individuals with disabilities live comfortable, independent lives.
AAC and Switches
Communication difficulties can limit autonomy, however, using an Augmentative and Alternative Communication (AAC) device allows individuals to communicate effectively when speech is challenging.
Additionally, motor differences may prevent the use of traditional input methods like mice or keyboards. In such cases, adaptive switches provide an alternative way for individuals to interact with technology.

Established Design Goals
- Compact and portable with internal power.
- Soft textures and calming colors.
- Quiet switches with some tactile feedback and customizable actuation distance.
- Large and stable keycaps with moderate concavity and custom layout.
- The keyboard also serves as an AAC device
- The keyboard acts as a switch interface box.
Everything Starts From the Keycaps and Layout
New Increased Surface Area (ISA) Keycap Profile
The ISA Keycap is slightly larger than regular keycaps and is more concave to help users with finger positioning.
Key Layout
The layout features configurable macro keys, as well as sticky keys for Ctrl, Shift, and Alt. These aid when typing one-handed.

Final Design
Tippy offers a user-friendly design with its vibrant orange and lilac colorways paired with soft-touch surfaces. The slim and rounded design makes it portable and approachable for everyone. The dedicated AAC mode features a clear green indicator and a large keycap. When activated, the built-in speaker plays pre-recorded phrases through the macro keys or speaks typed text in real time. Motor difficulties are accommodated with the added ISA keycap that provides a stable typing surface. Large buttons were positioned at the shoulders to provide an alternate way of interacting with mouse buttons. Additionally, the integrated switch interface allows direct connection of external switches.
