Inventory Functional Spec

From Second Life Wiki
Jump to: navigation, search

The Functional Spec explains how a user interacts with a feature, and what results they can expect from the feature. Ideally, the UI will indicate what the user can expect to happen next. Use screenshots when appropriate.

General Description

What does this feature do? Allows the user to store items.

Interface Requirements

How does the user use/activate this feature? Clicking the Inventory button or hitting ctrl-i.

Performance Requirements

Will this feature affect:

  • Client FPS? YES. Large inventories take longer to draw (perhaps this is fixed).
  • Simulator FPS? YES. Inventory is fetched from dataserver on the Simulator, so it may have a small effect on Simulator performance.
  • Database? YES. The dataserver fetches inventory from the Database.
  • Asset server? YES. Rezzing items reads from the Asset server. Creating inventory items writes to the Asset server.
  • Network load? YES. The inventory structure must be streamed to you. Rezzed or opened items must be streamed to you. Uploaded items must be streamed to the asset server.
  • Any other system? NO.

Design Constraints

  • Will this feature be unavailable on certain hardware? NO.
  • Is this feature consistent (similar look & feel) with other features? PARTIAL. Inventory has its own Menu, which is not accessible from the keyboard.
  • Is this feature well integrated (accessible when you need it, and in the place(s) you expect to find it)? YES.
  • Is this feature discoverable (newbie friendly)? PARTIAL. There's room for improvement.
  • Is this feature Safe, Predictable, and Responsive? YES.

Feature Dependencies

  • Features that this feature will affect

Attachments, Rezzing objects

  • Features that affect this feature

Upload Assets, Focus, Take, Take Copy


Security risks

  • Does this feature give access to something it should not? NO.

Feature Rules

The rules of the feature, organized in order of precedence. (eg. Rule 1 supersedes Rule 2, which supersedes Rule 3)

  • Object taken or returned into inventory go into their previous folder.
  • Returned object that have no previous folder will be put in the Lost and Found folder.
  • Accepted or uploaded assets of a certain type (eg. Clothing, Script, Animation) will go into a system folder of the same type.
  • Accepted categories will go into the Inventory folder.

Feature Usage

When appropriate, the feature will be laid out in chronological order, or in the order they are most likely to be used. (eg. Create a group, then add members, then deed land, ... kick members, leave group)

Drag rules

Esc will cancel a drag operation

dragging items onto another avatar or their name tag will give it to them

??dragging items onto avatars transparent attachment will not give the item to the av. ??Transparent is defined as 80%.

Rezzing an object by dragging it from inventory into world will keep the object highlighted, but not selected, in your inventory. If you hit delete once, the in-world object will be deleted, if you hit delete a second time the item in your inventory will Not be deleted, because it's only highlighted.

Inventory usability

Keyboard interaction

Hitting tab while focus is in the inventory will cycle focus between the search folder, the inventory tabs and the inventory contents (??what is the name of this portion of the window?).

Enter key operation:

  • objects - will open properties panel
  • everything else - view the item

Arrow keys:

  • The up and down arrow keys will move focus up and down in the inventory.
    • Pressing down while your cursor is in the search field will move focus to the "My Inventory" folder.
    • Pressing up while the "My Inventory" folder is focused will move the cursor into the search field.

The right arrow key will open a folder.

The left arrow key will close a folder.

The Home key will jump the inventory to the top, but will not move the selection.

The End key will jump inventory to the bottom, but will not move the selection.

The Page Up/Page Down keys will scroll up and down respectively, but will not move the selection.

Mouse interaction

Dragging items to the top or bottom of the inventory will scroll the inventory up or down.

Dragging items to the top of the inventory often inadvertantly opens the "Recent Items" tab.

if you have multiple inventories open close them all, and reopen inventory, the open folders will match that of the last inventory that was closed.

Metrics

Speed - how fast the inventory opens and loads.

Responsiveness - time between clicking/dragging an inventory item to ground and the cursor switching from "not" to "allow drop" (this time seems to be increasing - may be related to sim data server load)

Predictability - Do you know what's going to happen when you release the mouse button?

Safety - Do we help you avoid disaster?
