Description

BACKGROUND OF THE INVENTION

For many computer users the conventional mouse is not good enough for tasks that require precision movements. Tasks like electronic signature, drawing with graphical editors or computer aided design programs; some games require switching between tasks that require different level of precision. Conventional mouse is designed for good sliding over the surface with small effort, different improvements were done for convenient holding in hand and ergonomic use.

Computer mouse pads improved mouse movements, but no improvements can reach level of precision that humans can reach with simple pen. Pen-mouse system, U.S. Pat. No. 7,242,387 was invented, it is more precise, but not ergonomic for user, that is getting tired fast and less convenient for other tasks that do not require the extra level of precision. One of reasons for precise movement of pen in human hand is the resistance point over the work surface that it creates. Ergonomic computer mouse, U.S. Pat. No. 6,396,479 allow the little finger of user to drag on the work surface to assist in fine positioning but does not solve the problem completely. Proposed invention has a retrievable tip, which creates surface resistance point that is needed for precise positioning of the mouse, without losing ergonomic features.

In some embodiments, the tip is moved to working position by rod shaft, penetrating the base, which also have braking function based on penetration length, which is different from U.S. Pat. No. 6,362,811 where braking is done with little finger. And different from U.S. Pat. No. 8,223,124 where shaft does not have tip and used for different purpose.

In some embodiments, mouse is used with additional flat mouse pad, that have pattern of cavities or projections e.g. in form of grid or circle.

In some embodiments, mouse is used with a pad having cavities in grid pattern which together with the tip in working position creates a snap to grid like feature, which is different from Mouse pad, U.S. Pat. No. 6,187,398 that has one cavity.

Outward movement have different resistance from inward movement, where hand placed on table is proving resistance. Balancing the resistance is expected to be more convenient for some users and can be achieved by controlling the tip movement.

SUMMARY OF THE INVENTION

A computer mouse including a base with bottom surface for sliding across a work surface, with a retrievable tip for providing one or more resistance points for precision movements.

At retrieved position, the tip is not touching work surface, proving regular mouse movement. At working position, the tip is touching work surface and creating resistance for precise movement of the mouse over the work surface.

User may switch between retrieved and working positions preemptively or during mouse movement.

In some embodiments, the tip is moved to working position by rod shaft, penetrating the base. Button for switching between retrieved and working positions may be located on the side of mouse next to thumb or little finger. Increased penetration length of the tip will create braking function.

The switching mechanism may have a lock for holding rod at specific penetration length.

In different modifications of the mouse, the button locking mechanism is located under thumb, locks simultaneously the rod, and left (click) mouse button. This feature can be used for editors like Word when text painting is needed.

Electrical actuator instead of finger force can do rod movement.

In different modifications of the mouse, the rod movement can be programed to be triggered when mouse is moved forward, backward, sideward or to other direction according to user pre-selection. When movement in selected direction identified, a signal is sent to the actuator, which then will move rod to desired working position.

Moving rod with tip out of base to the braked position by electrical actuator will create braking effect to mouse movement. This action can be initiated by user, which is pressing initiation button or by program, which applied braking on deceleration part of path. When long path was identified by high initial speed and moving rod was in working position toward virtual object (possible target), rod is retrieved from working position for acceleration and constant speed part of path, and then moved in braked position on deceleration part of path.

Program based on initial speed, initial acceleration, and direction during movement and available targets on computer screen, predicting virtual objects (target or group of targets) and initiating braking. When single virtual objects cannot be distinguished out of group of virtual objects, braking applied at the part of path common to group and released reaching vicinity of virtual objects.

In different modifications of the mouse, the steering axle of the rod shaft can be at different angles to the base. The angle is generally between 30 and 90 degrees, depending on user convenience. Since majority of people are used to hold a pen at certain angle, expected that user who is accustomed to hold writing pen at low angle will prefer mouse with movable rod at the similar angle.

In different modifications of the mouse, the base includes a wheel with multiple tips at fixed positions where the user can choose the desired tip by rotating the wheel to the appropriate fixed position.

In different modifications of the mouse, an additional flat mouse pad with cavities in form of grid is provided, which together with the tip creates a snap to grid like feature.

Tips can be done in different shapes, using different materials. Typically, metal ball is used for tip. For glass, plywood surfaces instead of ball edge, other shapes may be used and or other materials with higher friction capability like rubber. Tip profile and form can create different resistance in different direction of movement.

Movement detection sensor baseplate can be lowered in order to keep same distance between sensor and bottom surface in different embodiment when tip is moved to working position.

For example, in modifications using bottom wheel, where baseplate in pressed against backside of wheel, that have cavity correspondent to tip length on other side of wheel if wheel is turned to working position back plated is lowered since it is pressed against cavity.

Computer mouse with tip in working position allows the user to make rotational movements/gestures around axis provided by tip. Computer program registering rotational movements/gestures and invoking actions on user behalf. For example, adjusting volume/brightness, changing selected/focused item, etc.

Computer mouse with tip in working position allows the user to make pressure gestures on the tip. Computer program registering pressure gestures and invoking actions on user behalf. For example, clicking at cursor position, changing selection radius based on pressure strength, etc.

These types of gestures can be alternative for traditional mouse-based gestures e.g. clicking/wheel spinning, and provide additional flexibility or alternatives especially important for users with disabilities.

In different modifications of the mouse, for activating special command by computer mouse, user is making rotational movement of mouse, when mouse is rotated over mouse pad with pattern of cavities or projections.

Computer mouse with tip in braked position allows users that have hand tremor to improve cursor positioning by stopping cursor in vicinity of target, then reaching target by rotational movement. User is moving computer mouse in direction of virtual target, when cursor is in vicinity of virtual target user is stopping mouse by activating rod mechanism that moving tip in to braked position, then user is reaching exact position by rotational movement of mouse.

Projections at mouse pad while projection height is changing from maximum to zero in certain direction are creating directional resistance, enabling additional accuracy and or identifying rotational movement.

Computer mouse is placed on the sloped surface, tip in working position prevents sliding from place that it was left.
