What is a track ball mouse?
A "ball mouse" or mechanical mouse is a computer mouse which detects user inputs using a system of servos detecting the movements of a ball (inside the mouse) which rolls on the desk surface. The most common alternative, the "optical mouse" uses optical sensors to detect user inputs. The optical mouse is widely considered to be superior in all important respects, and is therefore becoming much more common then their mechanical cousins.
Does an optical mouse need only software on computer?
Usually an optical mouse will be happy using the plain, generic mouse driver your operating system provides. There's nothing actually different about how the mouse talks to your computer just because it's optical. The optical data is for the mouse to process, not your computer, jusy as it was when there were trackballs in the devices.
Why does your Macintosh mouse jump around randomly?
Sometimes this can occur, with an optical mouse or a mechanical mouse (with a ball in it), if it's sitting just right; basically the wheel that detects movement in the mouse is sitting right where it would appear to be moving, and makes the mouse sensitive to vibration. An optical mouse doesn't have a wheel, of course, but its image sensor can get confused when it "sees" just the right image of the pad or table. Move the mouse ever so slightly and see if the random movement stops. If the mouse behaves erratically consistently, especially while you're using it, then the mouse itself is probably damaged.
Is an optical mouse or wireless mouse better?
It depends on what you like better. Wired mouse you always have to have a cord with and also a mouse pad. But with a wireless you have no cord and all you do is plug it into a unused usb outlest and no mouse pad required. Also the mouse will need one battery.
What is the difference between optical mouse and opto mechanical mouse?
A mechanical mouse (or "ball mouse") tracks the users input by sensing the movements of a ball which rolls on the desktop surface. This is done using a pair of small wheels at a 90 degree angle from each other which contact the mouse and are moved by the mouses movements. These movements are translated electrical signals by servos and then transmitted to the computer.An optical mouse tracks the users input by taking optical data from the desktop surface. This may consist of an optical sensor similar to the ones used in digital cameras, or may use laser diodes to detect tiny physical features of the desktop surface.Optical mouses generally have less moving parts than mechanical mouses in addition they have much higher sensitivity and are useable on almost any surface. This makes optical mouses much more popular than mechanicals, as a result the use of mechanical mouses is on the decline.Read more: What_is_the_difference_between_a_mechanical_mouse_and_an_optical_mouse
Difference between optical and mechanical mouse?
A mechanical mouse has a ball & rollers on the bottom which moves the pointer. An optical mouse has a light instead, and you don't even need a mouse pad to use it.
What does the optical mouse use?
Optical Mice Developed by Agilent Technologies and introduced to the world in late 1999, the optical mouse actually uses a tiny camera to take thousands of pictures every second. Able to work on almost any surface without a mouse pad, most optical mice use a small, red light-emitting diode (LED) that bounces light off that surface onto a complimentary metal-oxide semiconductor (CMOS) sensor. In addition to LEDs, a recent innovation are laser-based optical mice that detect more surface details compared to LED technology. This results in the ability to use a laser-based optical mouse on even more surfaces than an LED mouse. Here's how the sensor and other parts of an optical mouse work together: The CMOS sensor sends each image to a digital signal processor (DSP) for analysis. The DSP detects patterns in the images and examines how the patterns have moved since the previous image. Based on the change in patterns over a sequence of images, the DSP determines how far the mouse has moved and sends the corresponding coordinates to the computer. The computer moves the cursor on the screen based on the coordinates received from the mouse. This happens hundreds of times each second, making the cursor appear to move very smoothly. Optical mice have several benefits over track-ball mice: No moving parts means less wear and a lower chance of failure. There's no way for dirt to get inside the mouse and interfere with the tracking sensors. Increased tracking resolution means a smoother response. They don't require a special surface, such as a mouse pad.
Name of sensor used in optical mouse?
An optical mouse uses an image sensor that contains an array of monochromatic pixels. Along with sharing the same ASIC for storing and processing images, it accelerates the process of correlation by learning previous motions and using frame skipping to avoid dead bands.
How do you use a mouse as a joy pad when using an emulator?
there is some software that pretty much all it does is convert movement of the mouse into key presses...i havent seen anything that does anything with movement speed/sensitivity though
Why does the mouse pointer shake in MS windows Vista?
Are you using an optical mouse?(a mouse that uses a laser) My mouse would do that, if the surface of whatever it's on, such as the mousepad, has letters or lines or pictures or whatever on it it will affect the laser. Try putting a blank piece of paper over top of the mouse pad, it should fix it.
What is a sentence using the word optical?
The mirage was just an optical illusion.
Should you use a mouse pad with a optical mouse?
It depends. Primarily, it depends on what your desk is made of. Optical mice won't work at all on my (glossy, smooth, monochrome) desk, for example. Glass is particularly bad, usually. It also depends on the mouse - some of the newer ones have new technology being built into them that work on more surfaces. It also depends on what you are doing with it. If you want/need higher precision, smoother glide (or better grip), less mouse wear, and/or more comfort when using your mouse, you'll want a mousepad of some kind.
