TaMa - Task manager

TaMA is a modular desktop task board system that transforms scheduling into a tactile, focused ritual. A portable notebook feeds handwritten task cards into a sliding rail mechanism that reveals only one task at a time. Designed with embedded magnetic rails, TaMA adapts seamlessly to desktop, wall-mounted, and flexible workspace environments.

Design Criteria

Hand interacting with a tactile bumpy surface

Interactive & Tactile

To create a sense of joy and reinforce feelings of accomplishment, the design should offer satisfying, tangible interactions.

Seamless & Frictionless

The product should not overcomplicate the interactions that add friction for users. Instead, it should fit naturally and smoothly into their daily routines.

Redesigned Work Ritual

To effectively enhance an existing practice or ritual that people already practice, we provide a fresher and more enjoyable experience.

“Snap”

To achieve satisfying snap-in and release moments at both when attaching the sheet and when sliding or rotating the rail, I developed the set of mechanisms done using magnets through multiple rounds of iteration and testing.
