The RollerMouse Mobile by Contour Design is a compact version of the well-known RollerMouse Red, designed for mobility and ideally suited for use with compact keyboards. This central pointing device conveniently positions between the operator and keyboard space bar, keeping mousing activity "inline", i.e., in the area immediately in front of the keyboard, and eliminating the need to reach for a mouse. This also makes it suitable for use where there may be insufficient room for a mouse to be placed immediately beside the keyboard. Like all RollerMouse products, cursor movement is achieved by manipulating the tube-like cylindrical "rollerbar" with the fingertips. Rotating the rollerbar moves the cursor up and down, and sliding the bar from side to side accomplishes horizontal movement. Once the desired location is achieved, a left click can be generated by pressing down on the bar (the force required for this is adjustable from an ultra-light touch to highly tactile). Four tactile buttons and a clickable scroll wheel are located below the bar to generate left/middle/right clicks, copy, paste, and vertical scrolling. Cursor speed can be adjusted via a button on the right end of the RollerMouse Mobile, with five different speed settings from 600 to 3000 DPI. The RollerMouse Mobile also ships with two heights of rubber feet that can be used to elevate low profile compact keyboards to better match the rollerbar height. Controls can also be customized using the downloadable driver.

The RollerMouse Mobile is equipped with the same larger diameter rollerbar found on the RED, as compared to that on the FREE3 or PRO3. On the Mobile this 0.8" diameter bar is 3.875" wide and offers a finer degree of control, especially for vertical movement. The surface of the bar is textured with raised bumps that offer tactile feedback to further improve all aspects of cursor control. Innovative tracking technology on the RollerMouse Mobile further enhances cursor control, letting the Mobile work equally well on both single and multi-monitor workstations. All these design elements make cursor control more precise and effortless without compromising durability and the robust nature of the sturdy aluminum housing. To further improve the ergonomics even the traditional mechanical "click" has been replaced with a newer "virtual" clicking mechanism that generates a "percussion-free" but audible "click" that can be adjusted in volume or fully disabled if so desired.

Because the RollerMouse Mobile is designed for mobile use it offers features not available on the larger RollerMouse Red. The Mobile offers three connection options - to Bluetooth-enabled devices, via a an included 2.4 gHz wireless receiver, or as a wired device via the included charging cable. It also comes with a folding protective sleeve that attaches and closes magnetically.

While the RollerMouse Mobile can work perfectly well with any type or size of keyboard those using full-size or separated keyboards may wish to consider one of the full-size RollerMouse Models.

The Bluetooth Ergonomic Mouse from Microsoft is a basic medium-sized mouse designed for right-handed use by those with small to medium-sized hands. The contoured body provides a resting flange for the thumb to discourage the pinching action that many use when moving their mouse. The mouse is equipped with a clickable textured metal scroll wheel that features crisp detents. Two primary buttons offer the standard Right and Left clicks, with two additional thumb buttons for Back and Forward. Microsoft Mouse and Keyboard Center software facilitates custom programming of all buttons, scroll wheel functions, and DPI settings from 400 to 2400.

Bluetooth communication eliminates wire clutter and the ability to pair with up to three Window-based computers and switch seamlessly between them makes the Bluetooth Ergonomic Mouse an appealing option.
Note: Devices must support Bluetooth 4.0 or higher.

For those who prefer the reliability of a wired connection the Ergonomic mouse is also available in a wired version.

The MX Vertical Advanced Ergonomic Mouse from Logitech is their first attempt at offering a mouse which more aggressively reduces pronation than other mice in their line. The body of the MX Vertical is angled at a fixed 57° to reduce the risks associated with pronation of the forearm. The angled body is designed to provide the support necessary for the hand to "relax" while engaged with the mouse. However, those with smaller or narrower hands may find that they need to maintain a degree of tension to hold their hands "up" in position over the buttons. Large or wide hands will likely have less of a problem with this requirement to maintain hand position.

The MX Vertical is equipped with a top quality sensor capable of reading from 400 - 4000 DPI. Two nominal settings of 1000 and 1600 DPI can be adjusted anywhere within the range in 50 DPI increments. The top-mounted DPI button enables users to adjust the mouse as needed for basic or fine control movements. The scroll wheel has a rubber tire for grip and features distinct but soft detents. There are 4 programmable buttons (left, right, back, & forward).

The MX Vertical offers 3 connection options: Wired via the charging cord, 2.4Ghz Logitech Unifying Receiver with an operation distance up to 33 feet, and Bluetooth (Bluetooth Low Energy Technology required). The 270mAh Li-Po rechargeable battery can provide up to 4 months use on a single charge and offers a 1 minute Quick Charge that can provide up to 3 hours of use. Of course, individual usage may affect this. Using Logitech "FLOW" users are able to connect to and control up to 3 computing devices using a single mouse.

The "flatness" of the buttons on the MX Vertical prohibit the fingers from achieving a fully relaxed and naturally curved "position of function". This factor, combined with the almost slick surface on the buttons could lead users to try to "pinch" the mouse between the thumb and fingers in an attempt to achieve a better sensation of "control". In addition, to minimize the activation force on the buttons the fingertips need to be as close to the end of the buttons as possible. Those with large hands or very long fingers may be able to achieve this position but most users will find their fingertips falling short of this "optimum" position, resulting in a higher force being required for click activation.

The Pro Fit Ergo Vertical Wireless Trackball from Kensington offers thumb-operated cursor control that eliminates the traditional arm and hand movement required with a traditional mouse. It also moves the hand and forearm away from a prone position by angling the hand outward at 60°. The 34mm trackball offers silky-smooth movement with adjustable optical tracking from 400-1500 DPI. The contoured body provides a support for the hand, naturally positioning the fingers over the right and left buttons. Side scrolling function is provided by a tilting scroll wheel that features crisp detents, conveniently positioned between these buttons to complete the traditional mouse control layout. The index finger has easy access to convenient Back and Forward Buttons for browsing through multiple pages of a document or web page.

The Pro Fit Ergo Vertical Wireless Trackball offers Dual Connectivity that can simultaneously support connections to up to 3 computers or devices (1 via the included 2.4 GHz receiver and up to 2 more via Bluetooth.

As the Pro Fit Ergo Vertical Wireless Trackball places the workload fully upon the thumb, (which on most other trackballs is generally shared by several fingers), anyone who has existing thumb issues would be well-advised to consider alternative solutions.

The Pro Fit Ergo Wireless Mouse from Kensington presents with a body angle of approximately 40°, rotating the hand away from a traditional fully prone position. This wireless mouse is contoured specifically for right-handed use and operates plug-and-play. It is able to connect via either standard 2.4 GHz wireless with the included receiver dongle, or through Bluetooth 4.0 with devices that can support this option. A switch on the underside changes mode and doubles as a batter-saving power switch. Optional software is available for both Windows and Mac OS should one desire to customize the button functions. A convenient DPI switch just behind the scroll wheel accommodates quick access to three DPI settings (800, 1200 and 1600) to accommodate different work requirements. The wireless receiver can be stored in the underside of the mouse to ensure it isn't misplaced. The scroll wheel has detents to provide clear feedback response. The click action is somewhat soft and very quiet. This lack of tactile and auditory feedback may make it difficult to determine when clicks have truly activated and may lead to a greater degree of force being exerted, resulting in unnecessary stress on the fingers.

The size of this mouse means it is best suited for smaller to average sized hands as those with larger hands will find their palm either unsupported or their fingers extending past the end of the buttons, with the "inset" of the buttons into the body of the mouse making it difficult to perform clicks. The body is fairly narrow as well, encouraging "gripping" rather than permitting larger hands to relax.

The Wedge Touch Mouse is Microsoft's smallest mouse ever, designed primarily for use with tablets. Connecting to your device via Bluetooth, you don't need cords or wireless tranceivers; and with Microsoft's BlueTrack technology you can use the Wedge Touch Mouse on almost any non-glass surface with either hand. Its defining feature is four-way touch scrolling in every direction: up, down, left, and right. When not in use, the mouse shuts off automatically.
