The rechargeable R-Go Twister Mouse features an ergonomic ambidextrous design that can reduce the risk of mousing-related RSI. This is accomplished through both the 60° angle and the "twist" feature which lets the contoured upper body of the mouse "twist" 180° for either right or left-handed use. The 60° angle of the Twister Mouse greatly reduces pronation, supporting the hand and forearm in a more natural and relaxed position. Switching between left and right hands reduces the strain that is generally put on a single hand by spreading the work to both hands and allowing the hand and fingers to rest between sessions. There is also an illuminated Break reminder that can be activated and customized with the R-Go Break software to encourage regular breaks or switching between hands. Best suited for small or medium-sized hands (165-185 mm*), the Twister Mouse includes small cushioned pads to modify the height of the resting flange for the smaller or narrower hands.

The Twister Mouse has two buttons and a clickable scroll wheel for access to all standard functions and is equipped with an adjustable sensor offering five settings ranging from 400-2400 DPI. The dual-purpose charging/data cord lets it operate as a standard Wired Mouse in addition to the integrated Bluetooth. The 500 mAh rechargeable battery recharges in just two hours and can provide up to 150 hours of working time between charges. The Twister folds for transport and the included storage pouch offers protection during transport between home and office. * Sizing: The hand should be measured from the tip of the middle finger to the first crease in the wrist.

La souris rechargeable R-Go Twister Mouse présente une conception ergonomique ambidextre qui peut réduire le risque de RSI lié à l'utilisation d'une souris. Cela est possible grâce à l'angle de 60° et à la fonction "twist" qui permet au partie contourer du haut de la souris de "tourner" à 180° pour une utilisation par la main droite ou gauche. L'angle de 60° de la Twister Mouse réduit considérablement la pronation, soutenant la main et l'avant-bras dans une position plus naturelle et plus détendue. Le fait de changer entre la main gauche et la main droite réduit la tension qui est généralement sur une seule main en équilibrant le travail sur les deux mains et en permettant à la main et aux doigts de se reposer entre les sessions. Il y a également un Break reminder éclairé qui peut être activé et personnalisé avec le logiciel R-Go Break pour encourager les pauses régulières ou de changer d'une main à l'autre. Mieux adaptée aux mains de petite ou moyenne taille (165-185 mm*), la Twister Mouse vient avec des petits coussinets permettant de modifier la hauteur de la flange de repos pour les mains plus petites ou plus étroites.

La Twister Mouse a deux boutons et une molette de défilement cliquable pour accéder à toutes les fonctions standard. Elle est équipée d'un capteur ajustable offrant cinq ajustements allant de 400 à 2400 DPI. La corde de charge/données à double usage la permet de fonctionner comme une souris avec fil standard en plus du Bluetooth intégré. La batterie rechargeable de 500 mAh se recharge en seulement deux heures et peut fournir jusqu'à 150 heures de fonctionnement entre les charges. La Twister se plie pour le transport, et la pochette de rangement incluse offre une protection pendant le transport entre la maison et le bureau. * Taille: La main doit être mesurée du bout du doigt du majeur (middle finger) au premier pli du poignet.

The Wireless USB-C Mouse from Matias is a compact ambidextrous mouse that will fit those with small hands and facilitate load-balancing to reduce RSI risk from using just one hand. Powered by a single AA battery (not included), the 2.4 gHz wireless connection is made through the world's smallest USB-C wireless nano receiver that protrudes just 1/8" from the USB-C port to which it is attached. The small size of the receiver lets it remain attached for immediate reconnection as soon as the mouse is turned back on. Two DPI settings of 1000 & 1600 can be adjusted from the underside where the power switch is also located.

This hard plastic mouse has a light surface texture that is comfortable to the touch and eliminates the need for the rubberized finish commonly applied to many input devices and which can become tacky over time.

All four switches (Left, Right, Scroll Wheel, and Control) offer a smooth activation with crisp tactile feedback and a quiet but audible click. The lightly-textured aluminum scroll wheel features soft but distinct detents. Just behind the scroll wheel is the control button that functions as a Back button in Windows and can be custom programmed in Mac environments.

The Wireless USB-C Mouse is available in both White and Black and is plug-and-play in both Windows and Mac environments. For convenience it can also share a single USB-C Wireless Nano Receiver with Matias USB-C 2.4 gHz keyboards, making it a convenient partner for data input.

Kensington has taken their venerable Expert Mouse Optical to a new level with the new Expert Mouse Wireless Trackball. Longtime or novice trackball users now have the freedom of wireless available in a full-size trackball with the additional option of selecting whether to connect via Bluetooth 4.0 LE or traditional 2.4 GHZ wireless using a USB nano receiver. This unique dual-connection feature makes the Expert Mouse Wireless Trackball a good choice for those with a limited number of USB ports or who wish to use the trackball on multiple systems, employing Bluetooth on one and using the RF Receiver on a second or non-Bluetooth compatible system.

The Expert Mouse Wireless Trackball employs Diamond Eye optical technology for smooth, precise tracking and features the well-known Kensington Scroll Ring for quick scroll access on web pages and within lengthy documents. Four large buttons provide easy access to primary functions and can be easily customized to personal preferences through the Kensington TrackballWorks software. The ambidextrous design easily accommodates both right and left-handed use and includes a detachable rest to aid users in maintaining a more ergonomic neutral wrist alignment.

The BLUELINE Joystick from Pretorian is a technology-access device that connects via Bluetooth to any Apple devices with iOS13.4.1 onwards, Android devices, or other computing devices that have Bluetooth support, either internally or via an add-on bluetooth receiver dongle. The USB-rechargeable battery can provide up to 15 hours of continuous use. The BLUELINE Joystick is designed for those who may have limited hand control or strength, motor skill difficulties, poor hand-eye coordination, and lack of manual dexterity and offers excellent cursor control as well as up to 5 programmable button functions (3 on-board, 2 optional external). This functionality is packaged in a sturdy housing designed to survive under heavy use. The three on-board activation buttons are coloured and recessed to help guide the fingers into position. The symmetrical design makes this joystick suited for use with either hand by simply reprogramming the on-board switch configuration with the raised body providing support for the wrist.

The design of the BLUELINE Joystick offers precision control and requires minimal hand movement and just 0.5 Newtons of force to initiate cursor movement. The cursor moves very slowly when the joystick is minimally displaced from centre, permitting extremely accurate cursor positioning. As the displacement is increased the cursor accelerates to the chosen maximum speed (4 settings available). The adjustable maximum cursor speed also lets the BLUELINE Joystick be configured to serve the needs of those who may have limitations related to fine motor control, with the lowest cursor speed offering a greater level of control in that application. The joystick ships with the standard joystick, a T-Bar handle, or a soft-grip ball for configuration to meet personal requirements.

Three on-board buttons provide basic functions (primary functions vary with device) but are also custom programmable to perform a wide range of optional functions. The middle button is a lighter shade than the left and right buttons for easier identification. Dual mini-phono jacks also permit the attachment of external switches that can also be programmed. Available commands include Left Click, Right Click, Middle Click, Drag, Double Click, Delayed Drag, Swipe Left, and Swipe Right. Additional features and customization are also available. For full details on the available functions, customization of commands, and setup of the BLUELINE Joystick please read the User Manual.

The RollerMouse Go (formerly 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 Go, with ten different speed settings from 600 to 4000 DPI. The RollerMouse Go 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 Go is equipped with the same larger diameter rollerbar found on the RED, as compared to that on the FREE3 or PRO3. On the RollerMouse Go 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 Go further enhances cursor control, letting it 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 Go is designed for mobile use it offers features not available on the larger RollerMouse Red. This compact RollerMouse 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.

The optional RollerMouse Go Dock accessory is for those who want the convenience of the more compact RollerMouse Go for travelling but desire the ergonomic benefits afforded by a full-size RollerMouse when they are in the office. The RollerMouse Go simply sockets into the Dock to provide extended palm and wrist support not only directly in front of the RollerMouse Go but also to the right, where a full-size keyboard will have the navigation and numeric keypad. And, when leaving the office, the RollerMouse Go again simply detaches from the dock for full portability.

While the RollerMouse Go and Dock 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 JAZZ Joystick from Pretorian was designed to address the needs of those who may lack fine motor skills. It can provide standard cursor control as well as switch scanning access. Unlike most other joysticks, the JAZZ is designed to specifically accommodate gross motor movements while providing accurate cursor control and switch scanning. Because the high-quality analogue joystick requires just 0.5 newtons of force to activate it is able to also serve the needs of individuals who also have limited strength in addition to reduced fine motor skills.

The Jazz Joystick has buttons for left click, right click (or double click), and drag lock functions. Dual mini-phono jacks also permit the attachment of external switches to provide easier access to the Left click function and for switching from Mouse Mode to Switch Scanning Mode. Differing needs can be met by changing the control surface between the included standard joystick, t-bar handle, or soft-grip ball. The Jazz can also be easily switched for left-handed operation which swaps the functions of the left and right buttons.

The enhanced cursor control is achieved by only permitting cursor movement to occur when the joystick is moved within a prescribed range of the horizontal and vertical axes (Standard Mode) or standard and diagonal axes (Diagonal Mode). Cursor activation is accompanied by an audible "click" (optional) to provide notification that movement has been achieved. Under standard operation the cursor begins movement slowly, accelerating to the selected maximum speed (4 available). When engaged the optional SmartTrack function modifies this behaviour by considering how long the cursor has been idle, providing more effective cursor control for those who are able to take advantage of this function.

The JAZZ Joystick features a durable heavy duty housing designed to survive heavy use. High contrast coloured buttons and control surfaces aid in determining position and function of the controls. The symmetrical design enables works equally well with either hand without having to angle the wrist. The large, integrated hand support/palm rest makes work posture more relaxed and less strained.

Note: The latest release of iOS13 for Apple portable devices includes support for USB Pointing Devices. This means that virtually all of the Pretorian Mouse Replacement solutions can now be used with iPads and iPhones that have iOS13 or newer. Connection to the portable device requires a "camera adapter cable". Because the mousing device will be powered by the phone or tablet it is preferable to use one with pass-through charging so the portable device can charge while the mousing device is attached and in use.

The n-ABLER PRO Joystick from Pretorian is specifically designed to address the needs of computer users with limited hand control, motor skill difficulties, poor hand-eye coordination, lack of manual dexterity, and muscle spasms. This functionality is packaged in a "Professional" housing that will blend easily into office or classroom environments, reducing undesired attention. The glossy silver upper housing offers limited resistance to hand repositioning and the black buttons feature contrasting white legends for increased visibility.

The n-ABLER PRO Joystick provides cursor control as well as single-click controls for left click, right click, double click, and drag lock functions. In addition the n-Abler PRO Joystick also offers a locking "pan" function which enables vertical and horizontal scrolling using the trackball without the need to hold down a button. It also features an "Anti-Tremor" function with three settings to enhance cursor control for users experiencing hand tremors of varying degrees.
Users who experience muscle spasms or extreme tremors may be interested in considering the n-ABLER Joystick or n-ABLER Trackball, both of which feature an "AXIS LOCK" which locks the cursor to the Vertical or Horizontal Access.

Cursor control on the n-ABLER PRO Joystick is provided by a joystick control which can be equipped for the individual needs of a user. Included are a standard joystick, a T-Bar handle, and a soft-grip ball. Dual mini-phono jacks also permit the attachment of a variety of external switches to provide users with easier access to the Left and Right click functions. Users who find the traditional orientation unsuitable have the option of "teaching" the trackball to orient itself at 90° increments, freeing the user to change the housing orientation for optimum usage and comfort. The n-ABLER Joystick also offers an optional buzzer setting which provides notification as specific functions are activated or deactivated.

The design of the n-ABLER PRO Joystick offers precision control and requires only minimal hand movement. This can reduce wrist and elbow fatigue, as it requires noticeably less effort. The symmetrical design enables users to work with either hand without having to angle the wrist, and the unit can also be configured for left-handed operation. Its large, integrated hand support/palm rest makes work posture more relaxed and less strained.

The Mousetrapper Prime from Mousetrapper is an inline / central pointing device that offers the convenience and flexibility of both wired and wireless operation. As with all other members of the Mousetrapper family of devices, the Mousetrapper Prime facilitates cursor control through the innovative "steering pad". Incorporating features and concepts of both a touchpad and a treadmill, the steering pad offers fingertip control for precise cursor movement, left click activation and vertical scrolling. Eight programmable buttons, plus the steering pad, provide quick access to double click, left click, right click, zoom out, zoom in, cruise (or scroll) down, cruise (or scroll) up, copy, and paste functions. All buttons and cursor speeds are also fully reprogrammable if desired.

The Mousetrapper Prime sits directly below the keyboard with the steering pad centered below the alpha-numeric keys on a standard full-size keyboard and able to be controlled by either hand. The steering pad features a slip-free silicone traction surface for the finger tips, offering near-effortless onscreen navigation and cursor control. The fingers can rest on the steering pad between mouse activation tasks, with clicking accomplished simply by pressing down against the pad. Because the fingers are physically moving the steering pad there is a much greater degree of tactile feedback than is provided by traditional touchpads, which in turn facilitates a greater degree of accuracy and control. As well, because the steering pad is not touch-sensitive there is no fear of movement disruption if additional fingers contact the steering pad - in fact, most people will naturally use multiple fingers to move the pad, making it a more natural movement than traditional touchpad control. The two-dimensional steering pad also offers an intuitive interface that for some may be easier to adjust to than rollerbars, touchpads or trackballs.

The Mousetrapper Prime features replaceable and wipeable palm supports and has an attached "keyboard support" that can be folded out to elevate low profile keyboards or folded below the Mousetrapper when using more traditional keyboards. Like most central pointing devices, the Mousetrapper Prime requires no overextension of the shoulder joint, and can significantly reduce the risk of repetitive strain injuries to the muscles of the shoulder and upper back.

In addition to the above features, the functionality of the Prime is greatly enhanced by the downloadable MT Keys software, which includes the ability to paste text up to 254 characters long using a single button and to add user profiles. MT Keys can also be used to adjust the Mousetraapper Prime cursor speed (up to 2000 dpi). The wireless mode functions via USB with the included receiver, while the rechargeable battery has six months of battery life between charges.

The n-ABLER PRO Trackball from Pretorian is specifically designed to address the needs of computer users with limited hand control, motor skill difficulties, poor hand-eye coordination, lack of manual dexterity and involuntary muscle spasms. This functionality is packaged in a "Professional" housing that will blend easily into office or classroom environments, reducing undesired attention. The glossy silver upper housing offers limited resistance to hand repositioning and the black buttons feature contrasting white legends for increased visibility.

The n-ABLER PRO Trackball offers the same basic functions (cursor control, left click, right click, double click, and drag lock) as does the standard n-ABLER Trackball but in addition also offers a locking "pan" function which enables vertical and horizontal scrolling using the trackball without the need to hold down a button. It also features an "Anti-Tremor" function with three settings to enhance cursor control for users experiencing hand tremors of varying degrees.

Cursor control is provided by a large 63 mm, free-running ball which responds to minimal effort. To avoid accidental movement the trackball projects only slightly above the housing, with the activation buttons fully recessed to avoid accidental activation as well as to aid users in button targeting. Dual mini-phono jacks permit the attachment of a variety of external switches to provide users with easier access to the Left and Right click functions. Users who find the traditional orientation unsuitable have the option of 'teaching' the trackball to orient itself at 90° increments, freeing the user to change the housing orientation for optimum usage and comfort. The trackball also offers an optional buzzer setting which provides notification as specific functions are activated or deactivated.

The design of the n-ABLER PRO Trackball offers fingertip precision control and requires only minimal hand movement. This can reduce wrist and elbow fatigue, as it requires noticeably less effort.

The Orbitrack Control Ring from Pretorian provides users who have very limited range of movement or strength with a simple, almost effortless, means to perform cursor movement and click control.

The Orbitrack employs a touch-activated surface similar to a touchpad but without the necessity of continuous finger movement to 'steer' the cursor.Cursor direction is determined by where a finger is placed in relation to a central point in the touch ring. Once contact is made the cursor will begin slowly moving in the desired direction, gradually increasing the selected maximum rate of speed (4 selectable speed options are available). The cursor will continue to travel as long as the finger remains in contact - no further movement is required until a change of direction is desired. Direction change is accomplished by moving the finger to a new location on the control ring. This can be accomplished by breaking contact with the control ring surface and repositioning the finger to steer the cursor in the new direction or by sliding the finger to the new location. Users will vary in their ability to use the second option and may opt for the first method until they learn to better control the movement.

Requiring no hand or wrist movement, the Orbitrack represents a significant advance in computer input technology and is suitable for all computer users, particularly children and those with motor skill difficulties and movement impairment.
