Action: Drag the slider along the scale. Application: Volume, power, price, length, time position. Conditions: Click on the scale and enter exact input, if appropriate. <a id=\"variant-mouse-08-01\"></a>\n- Numerical scrubbing. Action: Drag a numeric field or label along an axis. Application: Quickly change the coordinate, quantity, size of a parameter. Conditions: Indicate the possibility of dragging; keep the normal number input. <a id=\"variant-mouse-08-02\"></a>\n- Rotation handle. Action: Move the pointer around the center or drag along the selected axis. Application: Device regulator, synthesizer, valve, instrument angle. Conditions: Do not allow a jump at the corner transition through a full turn. <a id=\"variant-mouse-08-03\"></a>\n- Two-dimensional controller. Action: Move a point inside the plane. Application: Color selection, two sound parameters, tactical aiming. Conditions: Label both axes and their ranges. <a id=\"variant-mouse-08-04\"></a>\n- Resize by edge. Action: Pull the border or corner marker. Application: Windows, panels, forms, impact area. Conditions: Provide a minimum size and sufficient grip area. <a id=\"variant-mouse-08-05\"></a>\n- Scaling while maintaining proportions. Action: Drag a handle with an aspect ratio constraint. Application: Images, models, layout elements. Conditions: Explicitly show the constraint state and anchor point. <a id=\"variant-mouse-08-06\"></a>\n- Rotation around a support. Action: Drag the rotation handle around a given point. Application: Rotate a model, part, room, camera. Conditions: Support and possible snaps at corners must be visible. <a id=\"variant-mouse-08-07\"></a>\n- Moving along an axis or plane. Action: Drag the corresponding part of the 3D manipulator. Application: Setting up objects, setting up a scene, designing. Conditions: Show the active axis and coordinate system. <a id=\"variant-mouse-08-08\"></a>\n- Deformation by control points. Action: Drag vertices, nodes or handles of a curve. Application: Shape editor, route, sculpting, flexible puzzle. Conditions: Restrict self-intersections if they are not allowed. <a id=\"variant-mouse-08-09\"></a>\n- Range with two boundaries. Action: Move start and end markers. Application: Clip trim, price range, attack interval, work area. Conditions: Define boundary crossing behavior. <a id=\"variant-mouse-08-10\"></a>\n- Direction and length of pulling. Action: The starting point serves as a support; the vector to the cursor sets the parameters. Application: Force and angle of impact, velocity vector, direction of construction. Conditions: Display vector and length limitation. <a id=\"variant-mouse-08-11\"></a>\n- Rotate the virtual trackball. Action: Move the pointer along the surface of a conditional sphere. Application: Inspection of a 3D model, rotation of a planet or a complex object. Conditions: This is a mathematical model of rotation, an ordinary mouse is enough. <a id=\"variant-mouse-08-12\"></a>"},{"id":"context","title":"Context and limits","body":"Author's working classification for designing games and interactions.
