[0001] PEN SHAPED OPTICAL MOUSE DEVICE

[0002] DESCRIPTION

[0003] FIELD

[0004] The present invention relates to a pen-type optical mouse device.

[0005] DEFINITIONS

[0006] As used in the present disclosure, the following terms are generally intended to have the meaning as set forth below, except to the extent that the context in which they are used indicates otherwise.

[0007] Mechanical Mouse: It means as understood in general parlance “the first type of mouse integrated with a metal or rubber ball which spin in all directions. The free movement of the ball on surface helps with the cursor movement in the computer. The biggest draw back in a mechanical mouse is the regular cleaning they will require due to the accumulation of dirt which will hinder with the cursor movement

[0008] Optical Mouse: It means as understood in general parlance “an advanced computer pointing device that uses a light-emitting diode (LED), an optical sensor, and digital signal processing (DSP) in place of the traditional mouse ball and electromechanical transducer”. Some optical mouse comes with wireless capabilities. Optical mouse here includes all light emission-based mouse e.g. laser light based mouse.

[0009] Stylus: A stylus is an instrument shaped like a pen, designed to be used with graphics tablets or devices that use touch screen input. It is used to write or draw on a screen, like show we would write / draw on a sheet of paper. Unlike a pen, styluses have a plastic or felt tip depending on its purpose and functionality. A stylus can come in two forms: passive (also known as a capacitive stylus) or active (also known as an active stylus or active pen).

[0010] BACKGROUND

[0011] Conventional mouse is operated in such a manner that the user moves the mouse on a plain surface such as a mouse pad to rotate the mouse ball, thereby moving the cursor or performing a click operation.

[0012] Traditional optical mouse is operated in such a manner that the user moves the mouse on a plain surface such as a mouse pad and the incident light falling on the plain surface is reflected from the surface, sensed by optical image sensor and on comparison of images it recognizes the movement, thereby moving the cursor or performing a click operation.

[0013] The pen shaped devices e.g. “stylus” are able to write on the surface of the tablet, such as a digitizer, laptops, computers etc. but they need to be in contact with surface of such devices and they are not able to perform standard mouse functions i.e. if we use stylus on a plane surface or mouse pad, it will not give any cursor movement or writing etc. on the said device neither mouse click function is possible.

[0014] These conventional mouse (optical, laser or otherwise) do not support user to write / draw on the computer screen like a writing pen writes / draws on a plain surface due to shape of the mouse.

[0015] Existing pen-type roller ball-based mouse devices fail to give desired accuracy of the optical mouse movement as the image sensors are not able to trace movement with accuracy because as the inclination of the mouse changes, the distance between the image sensor and the plane changes to deviate the focus, thereby preventing the operation of the mouse from being recognized (angular rotation and inclination issue).

[0016] None of the prior arts are addressing the angle of rotation and inclination (unique to each user as per their pen holding habits) issue in a pen type mouse device with accuracy / sensitivity / other functionalities as in conventional optical mouse with a cost-effective way.

[0017] Click or scroll function in existing pen-type mouse devices are difficult to use efficiently due to limited space over the pen shaped mouse and people prefer to use conventional mouse which has wider space to be controlled through palm and fingers to achieve click operation and this comfort takes away the benefit of writing / drawing like a pen.

[0018] Therefore, there is felt a need to provide a device that alleviates the afore-mentioned drawbacks.

[0019] OBJECTS

[0020] Some of the objects of the present disclosure are described herein below:

[0021] An object of the present invention is to provide pen-shaped mouse with a mechanically simplified method (to overcome inclination & angular rotation problem) with all functionalities of an optical mouse (wireless or otherwise) enabling the user to write / draw on a plain surface, which in turn appears on the computer screen as cursor movement and also perform all usual functions of a mouse.

[0022] Another object of the present invention is to provide pen-shaped mouse which even can be used on the surface of computer monitor / laptop / tablet etc. and perform all functions of an optical mouse even though the surface of the computer / laptop / tablet etc. is neither a touchscreen-based device nor having digitizer functionalities which work when the screen is touched by compatible pen / stylus or similar devices. In a way, the present invention is a pen shaped device having combined functionalities of optical mouse and functionalities of stylus for non- touch screen devices i.e. pen shaped optical mouse device can be used over the monitor of computer / laptop / tablet (non-touch screen devices) as well as on plain surfaces to write / draw / point / click and scroll functions to give input signal.

[0023] Another object of the present invention is to provide click or scroll functionalities in pen mouse in such a way that people have enough space between these switches to use it comfortably and get advantage of writing / drawing like a pen.

[0024] Another object of the present invention is to provide a pen shaped mouse which can be used as mouse and pen without reversing the pen device.

[0105] TECHNICAL ADVANCEMENTS AND ECONOMICAL SIGNIFICANCE

[0106] The present disclosure described herein above has several technical advantages including, but not limited to:

[0107] Addressing the angular and inclination issue in pen mouse with a simple and cost-effective mechanical set-up while ensuring continuous image sensing by optical image sensor as the optical image sensor remain parallel to surface irrespective of inclination or angular rotation is used while holding the pen mouse by user. To explain further, conventional mouse work only when the image sensor is parallel to the plain surface on which it is moving during operation. If a mouse is to be converted into pen shape then that parallel stage for image sensor is not possible as each user holds pen with different inclination and angular rotation.

[0108] • Providing a technical solution to Write / draw on non-touch screen devices by actually moving pen mouse on screen e.g. computer (laptop / desktop monitor) & tablet screen which is not possible with conventional mouse.

[0109] • Addressing Space Problem in pen mouse diameter / circumference is very limited resulting into technical issue of placing mouse click / scroll buttons, in current invention same is addressed and even user can freely align the buttons as per their preference. To elaborate further, the conventional mouse are moved around on a surface while holding through the palm of the user and there is wide surface available for left click , scroll wheel and right click, whereas if optical mouse is converted into a pen shape mouse, then space for mouse click function would be too less and click function by fingers will create hinderance for other click function buttons.

[0110] • Easy to draw and write along with mouse functions, through pen mouse device, with high accuracy which is not possible in conventional optical or ball roller mice.

[0111] • Easy set-up as per unique grasping / pen holding habits of users : current invention to very easy to set-up the pen mouse device to address the grasping habits of users and also for users writing with left hand or right hand.

[0112] • Improve the writing / drawing skills without using too many papers in actual i.e. open the desired font writing on computer screen and just practice by using optical pen mouse cursor over it again and again.

[0113] • Such cost-effective device can help students, engineers, designers to use their potential with ease and with multiple iterations which is not possible by use of conventional mouse. Cost effectiveness is possible due to only few additional critical components which addresses the inclination & angular issue and space management for mouse click buttons.

[0114] • Lesser maintenance or damage to the pen shaped mouse as it has no roller ball or moving parts to sense the change in surface images and generate the signal representing cursor movement.

[0115] • Easy to carry as optical pen mouse device uses very limited space.
