The pointing device has been an essential part of the PC since the graphical user interface (GUI) became popular over 20 years ago. It's been done in many styles and shapes, from a traditional wired mouse, to a gyro air mouse like the Azulle Lynk. On notebooks, it's done most often as a rectangular touch-sensitive pad in the palm-rest. If you're an avid notebook shopper, you might notice that there is more than one kind of touchpad. What we're going to do in this article is review the four basic types found today, along with their pros and cons.
Traditional Touchpads
- Definitive left- and right-click zone. It should be obvious where to press the pad to produce a right-click. Some notebook makers will put a dedicated line on the pad to indicate where the right.
- I prefer the Mac's trackpad to a mouse in every way but one. It's more comfortable, it relieves RSI, it can be used equally easily by the left or right hand, and it does scrolling and multitouch.
- Like the trackpad, the Apple mouse isn't clearly divided into separate click zones and sometimes doesn't support right-clicking out of the box, which can be frustrating. If you're a little.
Nov 19, 2016 In my case the bluetooth connection to my trackpad was messed up (and I could only right click). Right click on the apple logo, right click on system preferences, start typing Bluetooth and then key down to the Bluetooth preferences screen and press enter. You can right click the mouse/trackpad and disconnect and this immediately fixed the issue. Right-click in Windows with Boot Camp on Mac. In Windows on your Mac, you can do a secondary click, or right-click, using an Apple Mouse, Magic Mouse, or trackpad. Apple Mouse or Magic Mouse: Click the upper-right corner of the mouse. Trackpad: See Set trackpad options in Windows with Boot Camp. See also Get started with Boot Camp Control Panel on Mac Troubleshoot Boot Camp Control Panel.
The traditional two-button touchpad on the Dell Latitude E5570 business-class notebook.
The traditional touchpad is a rectangular, touch-sensitive pad, usually centered below the keyboard in the notebook's palm-rest. Mount device mac. Moving your finger across the surface of this pad moves the mouse. Below the pad are dedicated left- and right-click buttons, and sometimes a center-click.
The traditional touchpad was once the most popular type, but has taken a back seat in recent years next to buttonless touchpads, which we'll detail next. A modern example of a notebook with a traditional touchpad is the business-class Dell Latitude E5570.
The advantages of a traditional touchpad include ease of use, reliability, and accuracy. It's hard to mistake left- and right-clicks, because there are dedicated buttons for them. This style of touchpad furthermore tends to have the shortest learning curve, mainly due to its simplicity.
Here are key points we look for when evaluating traditional touchpads:
- Smooth surface. The pad should feel almost frictionless under your fingertips.
- Defined edges. It should be obvious by touch alone when your finger reaches the border of the pad.
- Appropriate size. The touchpad's physical size shouldn't feel confining relative to the notebook's screen size. It should also share the same aspect ratio as the screen.
- Quiet buttons. There's no reason to announce to someone on the other side of the room you've made a click, so the buttons should be as quiet as possible.
Buttonless Touchpads/Clickpads

The most popular style of touchpad on a notebook today is the buttonless touchpad, commonly referred to as a clickpad. It was originally made popular by Apple in the mid-2000s on the company's MacBook line.
This style of touchpad forgoes dedicated mouse buttons for a press-able surface. Simply press down on the surface at any point to produce a click. In other words, the entire surface is one big button.
The Lenovo Yoga 910 is an example of a consumer-grade Ultrabook with a buttonless touchpad, as is the Gigabyte P55W v6 gaming notebook. And of course, there's the Apple MacBook Pro (2016).
We've seen a drastic improvement in the quality and usability of buttonless touchpads since they started appearing in the notebook PC scene around 2010. These are the specific qualities we look for in buttonless touchpads:
Precise clicking action. Each click should have a direct feel, and not require too much movement.- Definitive left- and right-click zone. It should be obvious where to press the pad to produce a right-click. Some notebook makers will put a dedicated line on the pad to indicate where the right-click zone starts.
- Even click pressure. Pressing the pad in any particular location should require the same amount of actuation force as anywhere else. Much of this is dependent on how the pad is hinged. Most pads are hinged at the top, resulting in harder clicks at the top of the pad (furthest away from the user), and easier clicks at the bottom. Some difference in actuation force between the top and bottom of the pad is inevitable, but the difference shouldn't be a detriment to usability.
- No play in the pad surface. Resting your fingers on the pad's surface shouldn't cause it to move in any way. The pad's clicking action should be stiff enough that only a deliberate amount of pressure will cause the pad's surface to give way and actually produce a click.
More often than not, we've found buttonless touchpads to be deficient in one or more of the areas just described. This can result in a poor user experience for obvious reasons. It the clicks aren't precise enough, for example, this can slow down your interaction with the computer, thus reducing your productivity. And if you can't tell the difference between left- and right-clicks, you may find yourself frustrated.
Traditional touchpads generally aren't at risk for these problems, which is why we prefer them. But when buttonless touchpads are done right, they can work just as well.
Static/Haptic Feedback Touchpads

A distinct minority of notebook computers use a static touchpad. This style of touchpad looks like the just-described clickpads, but doesn't have any movement. Some of these pads incorporate haptic feedback, but not all.
The HP EliteBook Folio 1040 is an example of a notebook that uses a static touchpad; HP calls it the Forcepad.
Static touchpads tend to work well, but the lack of physical click feedback will probably feel unnatural until you spend significant time with it. This style of touchpad is typically used to add some other kinds of functionality, such as pressure sensitivity, which wouldn't make sense on a clickpad for obvious reasons.
Pointing Sticks
The UltraNav pointing stick solution on the Lenovo ThinkPad T460s.
Last but not least on our list is the venerable pointing stick. This is a classic alternative to a touchpad setup. The pointing stick is a rubber nub in the center of a notebook's keyboard, generally accompanied by dedicated clicking buttons beneath the spacebar. To move the mouse, place your finger on the nub, and gently push it in the direction you wish the mouse to go. It's similar to the trackball mouse in this respect.
The advantage with the pointing stick is that you don't have to remove your hands from the keyboard to use the mouse. With your hands on the keyboard in a typing position, you can reach the pointing stick with your index fingers. Moreover, your thumbs should be able to reach the buttons.
The pointing stick arrangement was once more popular than it is today. It can still be found on business-class notebooks from Lenovo, Dell, and HP. Lenovo's UltraNav solution on its ThinkPad notebooks is the most famous pointing stick setup. The ThinkPad T460s is a prime example. In our reviewing experience, we haven't found a version we prefer more than Lenovo's.
The pointing stick generally has a steeper learning curve than other variants, much again like a trackball mouse. Once properly configured, however, it can be just as effective of a pointing solution as any other. Purely from a productivity standpoint, it's hard to beat.
Conclusion
The fact there are multiple variations of pointing devices goes to show that there's no single best option. Much of it comes down to personal preference. On notebook computers, the traditional touchpad setup with dedicated buttons tends to be the safest choice, as it has the smallest learning curve, and provides the most consistent experience.
Buttonless touchpads, or clickpads as they're more commonly called, are the most popular type of touchpad on notebooks today. They can be hit or miss in terms of user experience; we'll refer you back to that portion of the article to see what we specifically look for when evaluating them.
Lastly, the classic pointing stick, made famous by Lenovo ThinkPads, continues to be a go-to for enthusiasts. It's arguably the simplest kind of pointing device, but also has a slight adjustment curve if you're used to a touchpad setup.
Of course, the only true way to find out what works best for you is to try it in person. Visit local stores, or ask family or friends if you can borrow one of their notebooks for a couple of hours. You can always take a look at our notebook reviews for our take on what's best. Also consider joining our community forum, which is free, and allows you to get expert advice from our members.
Mac Touchpad Right Click Not Working
A touchpad or trackpad is a pointing device featuring a tactile sensor, a specialized surface that can translate the motion and position of a user's fingers to a relative position on the operating system that is made output to the screen. Touchpads are a common feature of laptop computers as opposed to using a mouse on a desktop, and are also used as a substitute for a mouse where desk space is scarce. Because they vary in size, they can also be found on personal digital assistants (PDAs) and some portable media players. Wireless touchpads are also available as detached accessories.
Operation and function[edit]
Touchpads operate in one of several ways, including capacitive sensing and resistive touchscreen. The most common technology used in the 2010s senses the change of capacitance where a finger touches the pad. Capacitance-based touchpads will not sense the tip of a pencil or other similar ungrounded or non-conducting implements. Fingers insulated by a glove may also be problematic.
While touchpads, like touchscreens, are able to sense absolute position, resolution is limited by their size. For common use as a pointer device, the dragging motion of a finger is translated into a finer, relative motion of the cursor on the output to the display on the operating system, analogous to the handling of a mouse that is lifted and put back on a surface. Hardware buttons equivalent to a standard mouse's left and right buttons are positioned adjacent to the touchpad.
Some touchpads and associated device driver software may interpret tapping the pad as a mouse click, and a tap followed by a continuous pointing motion (a 'click-and-a-half') can indicate dragging.[1] Tactile touchpads allow for clicking and dragging by incorporating button functionality into the surface of the touchpad itself.[2][3] https://gxud.over-blog.com/2021/01/quiver-the-programmers-notebook-3-0-4.html. To select, one presses down on the touchpad instead of a physical button. What is the best search engine for mac. To drag, instead of performing the 'click-and-a-half' technique, the user presses down while on the object, drags without releasing pressure, and lets go when done. Touchpad drivers can also allow the use of multiple fingers to emulate the other mouse buttons (commonly two-finger tapping for the center button).
Touchpads are called clickpads if it does not have physical buttons, but instead relies on 'software buttons'. Physically the whole clickpad formed a button, logically the driver interprets a click as a left or right button click depending on the placement of fingers.[4]
Some touchpads have 'hotspots', locations on the touchpad used for functionality beyond a mouse. For example, on certain touchpads, moving the finger along an edge of the touch pad will act as a scroll wheel, controlling the scrollbar and scrolling the window that has the focus, vertically or horizontally. Many touchpads use two-finger dragging for scrolling. Also, some touchpad drivers support tap zones, regions where a tap will execute a function, for example, pausing a media player or launching an application. All of these functions are implemented in the touchpad device driver software, and can be disabled.
History[edit]
By 1982, Apollo desktop computers were equipped with a touchpad on the right side of the keyboard.[5] Introduced a year later, in 1983, the first battery powered clamshell laptop, the Gavilan SC included a touchpad, which was mounted above its keyboard, rather than below, which became the norm.
In in 1989 a touchpad was developed for Psion's MC 200/400/600/WORD Series .[6] Laptops with touchpads were then launched by Olivetti and Triumph-Adler in 1992.[7]Cirque introduced the first widely available touchpad, branded as GlidePoint, in 1994.[8]Apple Inc introduced touchpads to the modern laptop in the PowerBook series in 1994, using Cirque's GlidePoint technology;[9] later PowerBooks and MacBooks would use Apple-developed trackpads. Another early adopter of the GlidePoint pointing device was Sharp.[8] Later, Synaptics introduced their touchpad into the marketplace, branded the TouchPad. Epson was an early adopter of this product.[8]
As touchpads began to be introduced in laptops in the 1990s, there was often confusion as to what the product should be called. No consistent term was used, and references varied, such as: glidepoint, touch sensitive input device, touchpad, trackpad, and pointing device.[10][11][12]
Users were often presented the option to purchase a pointing stick, touchpad, or trackball. Combinations of the devices were common, though touchpads and trackballs were rarely included together.[13] Since the early 2000s, touchpads have become the dominant laptop pointing device as most laptops produced during this period beyond include only touchpads, displacing the pointing stick.
Use in devices[edit]
Touchpads are primarily used in self-contained portable laptop computers and do not require a flat surface near the machine. The touchpad is close to the keyboard, and only very short finger movements are required to move the cursor across the display screen; while advantageous, this also makes it possible for a user's palm or wrist to move the mouse cursor accidentally while typing. Touchpads also exist for desktop computers as an external peripheral, albeit rarely seen. Touchpads are sometimes integrated in some desktop computer keyboards, particularly keyboards oriented for HTPC use.
One-dimensional touchpads are the primary control interface for menu navigation on second-generation and later iPod Classic portable music players, where they are referred to as 'click wheels', since they only sense motion along one axis, which is wrapped around like a wheel. Creative Labs also uses a touchpad for their Zen line of MP3 players, beginning with the Zen Touch. The second-generation MicrosoftZune product line (the Zune 80/120 and Zune 4/8) uses touch for the Zune Pad.
Apple's PowerBook 500 series was its first laptop to carry such a device,[14] https://txriii.over-blog.com/2021/01/pre-order-skyrim-xbox-one.html. which Apple refers to as a 'trackpad'. When introduced in May 1994, it replaced the trackball of previous PowerBook models. In late 2008 Apple's revisions of the MacBook and MacBook Pro incorporated a 'Tactile Touchpad' design with button functionality incorporated into the tracking surface.[2][3][15] Beginning in the second generation of MacBook Pro, the entire touchpad surface acts as a clickable button.[16]
Laptops today feature multitouch touchpads that can sense in some cases up to five fingers simultaneously, providing more options for input, such as the ability to bring up the context menu by tapping two fingers, dragging two fingers for scrolling, or gestures for zoom in/out or rotate.
Psion's MC 200/400/600/WORD Series,[6] introduced in 1989, came with a new mouse-replacing input device similar to a touchpad,[17] although more closely resembling a graphics tablet, as the cursor was positioned by clicking on a specific point on the pad, instead of moving it in the direction of a stroke.
Theory of operation[edit]
There are two principal means by which touchpads work.[citation needed] In the matrix approach, a series of conductors are arranged in an array of parallel lines in two layers, separated by an insulator and crossing each other at right angles to form a grid. A high frequency signal is applied sequentially between pairs in this two-dimensional grid array. The current that passes between the nodes is proportional to the capacitance. When a virtual ground, such as a finger, is placed over one of the intersections between the conductive layer some of the electrical field is shunted to this ground point, resulting in a change in the apparent capacitance at that location. This method received U.S. Patent 5,305,017 awarded to George Gerpheide in April 1994.
The capacitive shunt method, described in an application note by Analog Devices (not to be confused with analog devices),[18] senses the change in capacitance between a transmitter and receiver that are on opposite sides of the sensor. The transmitter creates an electric field which oscillates at 200–300 kHz. If a ground point, such as the finger, is placed between the transmitter and receiver, some of the field lines are shunted away, decreasing the apparent capacitance. Trackpads such as those found in some Blackberry smartphones work optically, like an optical computer mouse.
