System Requirements Document for mars-yeah

1. Introduction

Focus Cube is a compact smart desk gadget that helps people stay focused while working or studying. Its central interaction is physical and immediate: a user flips the cube to a selected side, and the corresponding timer starts automatically.

The product is intended for students, freelancers, creators, remote workers, and professionals who struggle with distractions and want a simple way to manage focused work sessions without relying on a complex productivity application.

Tagline: Flip it. Focus. Get it done.

2. System Overview

Focus Cube is a physical hardware product designed for use on a desk. It provides three fixed timer modes through different cube sides:

• 25-minute focus
• 50-minute deep work
• 10-minute break

The cube is compact, rechargeable, and equipped with a simple LED indicator that communicates the currently active mode. A user begins a session by physically flipping the cube to the desired mode; no manual timer-start interaction is part of the current product scope.

The current public product information surface is the Landing page. It communicates the product, its use model, its modes, its LED indicator, rechargeable battery, and its premium desk-friendly design.

Current Product Boundaries

The current product includes:

• A small, compact physical desk cube.
• Three fixed flip-to-start timer modes.
• Automatic timer activation after a valid mode-facing flip.
• A simple LED indicator for the current mode.
• A rechargeable battery.
• A minimal, modern, premium physical-product aesthetic.
• A public Landing page that explains the product.

The current product does not include:

• A productivity dashboard.
• A mobile application.
• A web application for running timers.
• User accounts, authentication, or user profiles.
• Manual timer-start controls.
• Custom timer durations.
• Additional timer modes.
• Social, gamified, collaborative, or reporting features.
• Purchase checkout, payment processing, order management, or shipping workflows.

2a. Product Interpretation and Delivery Boundary

Focus Cube is primarily a physical hardware experience rather than a software application. The user’s primary interaction occurs directly with the cube: placing or flipping it to the desired timer side begins the relevant session automatically.

The Landing page is a public informational product surface. It presents the product and its physical interaction model but does not replace the cube’s controls, create timer sessions, store personal activity, or require user identity.

The creative direction includes a visually prominent purchase-style call-to-action treatment on the Landing page. Current requirements do not define commerce, checkout, payment, retailer integration, ordering, or fulfilment. Therefore, the call-to-action may be displayed as part of the visual composition but must not imply an implemented transaction or an available purchase workflow.

  • Recovery: users can continue reading the mode descriptions and product explanation without reliance on animation or product-render loading.
  • Reduced-motion state: the product remains visually composed in a still orientation, with the 25-minute mode visibly indicated.

3. Functional Requirements

FR-1 — Focus Cube physical focus support

As a Focus Session User, I should be able to use a compact smart desk cube while working or studying so that I can manage focused work sessions with minimal distraction.

• Provenance: explicit
• Trigger or input: The user places and interacts with Focus Cube at their desk during work or study.
• Required result: The cube provides a physical, desk-friendly means of selecting a focus or break session.
• Access state: No account, application identity, or software sign-in is required.
• Failure and recovery: If the cube is not powered, the user cannot begin a timer session and must recharge the device before retrying. This recovery behavior is a required inference because the device is rechargeable and must be powered to operate.
• Continuation: After the cube is powered and positioned, the user can flip it to one of the supported timer modes.
• Acceptance criteria:
  • Focus Cube must be a physical smart desk gadget.
  • Focus Cube must support use during work or study.
  • Focus Cube must be compact and suitable for placement on a desk.
  • The product must not require a productivity dashboard or software timer interface for its primary use.

FR-2 — Fixed timer mode sides

As a Focus Session User, I should be able to choose between 25-minute focus, 50-minute deep work, and 10-minute break modes by using different sides of the cube.

• Provenance: explicit
• Trigger or input: The user selects the desired cube orientation.
• Required result: The device recognizes one of the three supported mode sides.
• Access state: Physical device use; no application identity is required.
• Failure and recovery: If the cube is not positioned on a recognized supported mode side, no supported timer mode should be represented as active. The user can correct the orientation by placing the desired supported side face-up. This is a required inference needed to distinguish supported modes.
• Continuation: Once a supported side is face-up, the associated timer begins automatically.
• Acceptance criteria:
  • The cube must provide a 25-minute focus mode.
  • The cube must provide a 50-minute deep work mode.
  • The cube must provide a 10-minute break mode.
  • Current modes are limited to these three modes.
  • The product must not provide custom durations or additional timer modes in the current release.

FR-3 — Flip-to-start timer activation

As a Focus Session User, I should be able to start the selected timer by flipping the cube so that I can begin without manually starting a timer.

• Provenance: explicit
• Trigger or input: The user flips the cube to the mode they want.
• Required result: The corresponding timer starts automatically after the cube is flipped to the selected mode.
• Access state: Physical device use; no identity, sign-in, app pairing, or manual start control is required.
• Failure and recovery: If the device is unpowered or the selected orientation cannot be recognized, the timer does not start. The user must recharge the device if necessary or reposition the cube to a supported mode side, then retry. These mechanics are required inferences necessary for usable physical timer operation.
• Continuation: The user can remain in the active work or break session until its selected duration completes.
• Acceptance criteria:
  • Flipping the cube to a desired supported mode must automatically start that mode’s timer.
  • The timer-start interaction must not require a manual start button, software command, or additional setup step.
  • A flip to the 25-minute focus side must start a 25-minute focus timer.
  • A flip to the 50-minute deep work side must start a 50-minute deep work timer.
  • A flip to the 10-minute break side must start a 10-minute break timer.

FR-4 — Active-mode LED indication

As a Focus Session User, I should be able to see the current timer mode through a simple LED indicator so that I can confirm the mode I selected.

• Provenance: explicit
• Trigger or input: A supported cube mode becomes active after the user flips the cube.
• Required result: The LED indicates the current active mode.
• Access state: Physical device use; no account or application access is required.
• Failure and recovery: If the LED cannot be seen because the device is unpowered, the user must recharge the cube before relying on the indicator. If the selected mode is unclear, the user can reorient the cube to the desired supported face. This is a required inference needed to maintain observable mode confirmation.
• Continuation: The user may continue the active focus, deep-work, or break session with the LED indicating the active mode.
• Acceptance criteria:
  • The cube must include a simple LED indicator.
  • The LED indicator must show the current mode.
  • The current mode must correspond to the mode selected through the cube’s physical orientation.
  • The LED must not be presented as a dashboard, screen-based productivity interface, or additional configuration system.

FR-5 — Timed-session completion

As a Focus Session User, I should be able to rely on the selected mode to remain active for its specified duration so that I can complete a focus, deep-work, or break interval.

• Provenance: required_inference
• Rationale: A timer must run for its stated duration and reach an observable completed state for the accepted focus, deep-work, and break modes to be usable.
• Trigger or input: A supported timer starts after the cube is flipped.
• Required result: The active timer progresses for the mode’s fixed duration and reaches completion.
• Access state: Physical device use; no identity or application access is required.
• Failure and recovery: If a session is interrupted by loss of power, the device cannot continue the active timed session. The user can recharge the cube and start a new session by flipping it to the desired mode. No persistence or session-resume behavior is required.
• Continuation: After a timer completes, the user may begin another supported mode by flipping the cube.
• Acceptance criteria:
  • A 25-minute focus session must have a 25-minute timer duration.
  • A 50-minute deep-work session must have a 50-minute timer duration.
  • A 10-minute break session must have a 10-minute timer duration.
  • The current scope does not require timer-history storage, notifications, audio alerts, analytics, or completed-session reporting.

FR-6 — Rechargeable operation

As a Focus Session User, I should be able to recharge Focus Cube so that I can continue using its timer modes and LED indicator.

• Provenance: explicit
• Trigger or input: The cube requires restored power.
• Required result: The device can be recharged for continued operation.
• Access state: Physical device use; no software account or application interaction is required.
• Failure and recovery: When the device lacks sufficient power, timer activation and LED mode indication may be unavailable. The user restores availability by recharging the device and then flipping it to a supported mode.
• Continuation: After recharging, the user resumes normal use by selecting a mode through a physical flip.
• Acceptance criteria:
  • Focus Cube must have a rechargeable battery.
  • The product must support continued use after recharging.
  • The current scope does not define battery capacity, charge duration, charging connector, charging dock, wireless charging, or battery-status display.

FR-7 — Premium desk-friendly physical design

As a Focus Session User, I should be able to keep Focus Cube on my desk as a minimal, modern, premium object so that it fits naturally into my workspace.

• Provenance: explicit
• Trigger or input: The user places the cube in a work or study environment.
• Required result: The cube presents as a compact, premium desk accessory rather than an intrusive productivity device.
• Access state: Not applicable; this is a physical-product design requirement.
• Failure and recovery: If the product’s physical design obstructs normal desk use or does not convey the intended minimal, modern, premium quality, it does not meet the design requirement. Product design must be revised before release.
• Continuation: The user can continue to use the cube as a visible desk object and physical timer.
• Acceptance criteria:
  • The cube must be compact and small enough for a desk.
  • The cube design must be minimal.
  • The cube design must be modern.
  • The cube design must be premium.
  • The product’s visual character must suit a work desk.

4. User Personas

Focus Session User

Provenance: required_inference from the accepted target-customer groups and their stated focus-session needs.

The Focus Session User represents students, freelancers, creators, remote workers, and professionals who struggle with distractions and want a simpler way to manage focused work sessions.

Their product context is a desk, study area, home workspace, studio, or professional workspace where a physical focus ritual is preferable to opening another app, navigating settings, or interacting with a dashboard.

Primary goal

Begin and complete a focused work, deep-work, or break interval with minimal friction.

Accepted responsibilities

• Choose between the 25-minute focus, 50-minute deep work, and 10-minute break modes.
• Physically flip Focus Cube to the desired mode.
• Confirm the selected mode through the LED indicator.
• Use the active interval for work, study, deep work, or a break.
• Recharge the device when power is needed for continued use.

Relevant inputs and decisions

• Decide whether the current task requires a 25-minute focus session, 50-minute deep-work session, or 10-minute break.
• Select the physical cube side corresponding to that decision.
• Decide when to begin another supported session after the current session ends.

Interaction with other participants

There are no other accepted human participants. The user interacts directly with the physical Focus Cube.

Observable success

The user sees the selected mode indicated on the cube, begins the corresponding timer by flipping the device, and completes or continues a focused work or break routine without needing a manual timer-start interface.

6. Visuals Colors and Theme

Muse: Jony Ive
Headline: Quiet precision for a ritual object

Focus Cube should feel like premium consumer hardware rather than a productivity dashboard. The visual system must make focus feel tactile, calm, and immediate, with the cube treated as a carefully resolved desk object.

Colour Tokens

• Blue and indigo are forbidden.
• White or near-white page backgrounds are forbidden.
• The chartreuse accent must remain sparse and purposeful.
• Body copy on dark surfaces must use #F3F0E9 or #D9D5CC.

Typography

• Headings: DM Sans Light through Medium.
• Body: Manrope.
• Mode labels: Manrope Medium, uppercase, 0.14em letter spacing.
• Heading tracking: approximately -0.045em.
• Heading casing: sentence case, except for intentional display treatment and compact mode labels.
• Body size: 16px with 1.55 line-height.

Desktop type scale: 120px / 88px / 64px / 40px / 24px / 16px
Mobile type scale: clamp toward 64px / 52px / 40px / 30px / 22px / 16px

Shape and Surface Language

• Use continuous cube-inspired corner radii between 20px and 28px.
• Use hairline aluminium-grey rules as primary separators.
• Use circular LED points and flush controls.
• Avoid decorative pills, elevated cards, soft shadows, arbitrary rounded containers, glassmorphism, and floating dashboard panels.
• Every curve must visually echo the softened geometry of the physical cube.

Layout

• Use a wide 12-column layout with generous side margins.
• Maintain long horizontal breathing space.
• Use a whisper-thin top rail rather than busy navigation chrome.
• Organize content as product chapters separated by precise hairline rules.
• Alternate expansive product-stage sections with narrow, ordered specification strips.
• Do not use a conventional feature-card grid.

Imagery

• Use studio-lit macro photography and photorealistic product renders only.
• Present satin ceramic-white cube surfaces, a precise chartreuse LED aperture, matte desk grain, subtle charging-port detail, and quiet desk still lifes.
• Crop images tightly to show material honesty.
• Do not use stock office teams, vector illustration, decorative gradients, generic device mockups, motivational stickers, cartoon imagery, or confetti.

7. Signature Design Concept

The Quarter-Turn Object Stage

The Landing page opens on an uninterrupted graphite product stage in which Focus Cube is treated as the central physical ritual object.

A near life-size satin ceramic-white cube occupies the right seven columns and sits just above a razor-thin shadow plane. The visible upper face reads “25” as an integrated pale display, while a chartreuse LED seam glows along one cube edge. The far-right edge contains a fixed, hairline mode rail listing:

• 25 FOCUS
• 50 DEEP
• 10 BREAK

The left five columns present the tagline as a quiet editorial stack:

FLIP IT.
FOCUS.
GET IT DONE<span style="color:#D8FF3E">.</span>

A low, wide chartreuse purchase-style bar is cut into the bottom edge of the copy column. It is a visual composition element only until a source-defined commerce destination exists.

The rest of the Landing page expands this first-frame idea into a physical product narrative: the cube turns through its three accepted orientations, the active mode rail entry illuminates as each mode chapter appears, and an instrument-style specification band reinforces the object’s compact, rechargeable, desk-ready nature.

8. Interaction Model & Motion Direction

Interaction Model: Animated
Motion Tempo: restrained
Hero Dimensionality: layered_2d

Landing Hero Motion Brief

Focal subject: A near life-size Focus Cube render with satin ceramic-white surfaces, an integrated “25” display face, and a chartreuse LED seam.

Input → transformation → outcome thesis: The Focus Session User flips the physical cube to choose a mode; the Landing hero translates that accepted gesture into one deliberate visual quarter-turn, landing the cube on the “25” face and settling the LED into the 25-minute focus signal.

Motion vocabulary:

• One slow, deliberate 90-degree cube turn on initial load.
• Immediate LED transition when explanatory mode states change.
• Subtle physical weight shift rather than floating movement.
• Product-detail dissolves on scroll using 350–600ms ease-out timing.
• No bounce, particles, perpetual animation, parallax effects, or decorative motion.

Composed first frame:

• Graphite #151615 background.
• Large Focus Cube object stage on the right side of the page.
• Cube visibly resting above a fine shadow plane.
• “25” face visible as the active initial state.
• Chartreuse LED seam illuminated.
• Split three-line tagline on the left.
• Fixed right-edge mode rail with 25 FOCUS illuminated.

Reduced-motion state:

• The cube remains still in its composed 25-minute orientation.
