The Handshoe Mouse from Hippus NV is designed to eliminate the 3 most common issues associated with the use of a computer mouse - gripping, pinching, and tensing of the fingers. The unique naturally supportive contours of the Handshoe Mouse permit the hand and fingers to completely relax whether actively engaged with the mouse or just resting between movements —like they do in a well-worn glove. This relaxed position eliminates the sustained static tension that most tend to maintain when using a mouse and which are associated with the development of RSI. With multiple size options available —4 for the Right and 3 for the Left— anyone can receive full support of the hand, wrist and fingers while actively mousing. The recommended usage for this mouse is on the desk surface with the forearm fully supported by the desk or arm rest of the chair.
The Handshoe Mouse does not require any passive muscle tension or use, and prevents excessive muscle exertion during active use, making it the only mouse on the market that is almost impossible to use incorrectly. The waterfall design of the Handshoe Mouse provides a naturally curved resting support for the fingers, allowing them to fully relax between clicks. This eliminates the negative effects from an anticipation of the click which on traditional mice results in raised, hovering fingers as well as overexertion and overextension of the extensor muscles. The design also incorporates a thumbrest which supports the thumb in a neutral and relaxed fashion making the Handshoe Mouse a good option for those experiencing thumb-related issues such as DeQuervain’s Tenosynovitus.
The optical tracking uses advanced BlueRay Track technology combined with a 1500 DPI sensor which will work on almost any surface. Two light click force buttons (three on the large model) and a scroll wheel (clickable for middle click) provide standard "Plug-and-Play" mouse functions. The Handshoe mouse Wireless features a long-life rechargeable lithium battery for convenience and comes with a charging cord. Those who would rather have a wired model can share the same benefits in the Handshoe Mouse wired version.
Due to the greater amount of weight resting on a Handshoe Mouse (larger mouse, weight of hand and part of forearm) it is recommended that a firm, low friction mousing surface be used to reduce the effort required to move it.
Eliminates Static Grip Force - The anatomically derived design with full base surround cradles the hand completely, preventing one from gripping or pinching the mouse. The shape and sculpting of the Handshoe Mouse effectively harness the force of gravity on the hands alone to give full mouse control without requiring any static grip force.
Reduces Pronation - The Handshoe Mouse creates a sloped position of the hand which reduces pronation by 20° (the hand when on the mouse is sloped with the thumb higher than the fifth finger). This reduction in pronation reduces tension in the tissues and tendons of the forearm because the forearm is no longer being required to maintain the hand in an unnatural "palm down" position. Learn More About Pronation.
Reduces Wrist Extension - Another risk factor that the Handshoe Mouse addresses is wrist extension, which can be made worse with mice that have too high a profile at the rear without gradual inclined support for the wrist. The gently tapered back of the Handshoe Mouse, however, provides such support through the elongated "ramp" that allows the hand and arm to gradually incline from the desk to the front buttons, preventing the wrist from excessive extension. This ramp also prevents one from planting the base of their palm and and trying to maneuver the mouse employing just their their wrist and fingers— another behaviour known to greatly increase the risk of developing serious Repetitive Strain Injuries (RSI). Learn More About Wrist Extension.
Reduces Potential for "Anticipation of the Click" and Eliminates Finger Extension - The organic waterfall shape of the buttons means that the fingers are in a relaxed, curled "position of function" when resting on the Handshoe Mouse. No hovering of the hand (which can lead to development of Trigger Finger), or stretching of the fingers or thumbs is ever required when using on this mouse. Learn More About Trigger Finger.
Reduces Hand and Arm Fatigue - The body shape, dimensions, and angle of the Handshoe Mouse are all carefully calculated to position the forearm and hand in a position which requires the least static tension in the muscles and tendons. The formed orthopaedic support eliminates any need to maintain tension to hold the hand and fingers in place. They are now able to remain at rest until there is a need for movement. For the fingers this movement becomes very minimal as they are already in position on the buttons and require nominal effort to slightly curl and relax (a natural action) to perform a click action. The forearm is also relaxed as cursor movement is spread throughout the fore and upper arm zones.
Load Spreading - Workers can gain the maximum benefit from the Handshoe Mouse when the work surface or chair arm are correctly positioned to provide support for the forearm. Utilizing this support ensures that the wrist is positioned in as neutral a position as possible, reducing the risk of potentially damaging Wrist Extension. It also ensures they can avoid placing the weight of the forearm on the base of the palm, and facilitates load balancing of movement between the wrist, arm and elbow. By transferring much of the force required for mousing to the stronger muscles of the arm instead of the weaker muscles of the wrist or hand, the overall workload can be distributed in the manner most appropriate for each individual.
Sculpted Body Shape: The design elements that make the Handshoe Mouse ergonomic are combined in such a way as to provide maximum ergonomic benefits while maintaining an attractive and stylish look. Many have commented that it almost looks organic, and bears some similarities in appearance to a Manta Ray.
Multiple Sizes (4 Right-Handed and 3 Left-Handed): Just as one size of glove won't fit all hands, nor can a mouse. Because the Handshoe Mouse is designed to fit the hand just as a glove would, it must be able to accommodate different hand sizes and come in both left and right handed versions. As a consequence there are seven distinct models available. To determine which size is appropriate for the hand, see the Handshoe Mouse sizing chart.
Two Buttons for Extra-Small, Small and Medium Sizes: The Extra-Small, Small and Medium sizes of the Handshoe Mouse have two tactile switches corresponding to left and right mouse clicks. Between these is a clickable scroll wheel (slightly smaller than a standard scroll wheel) that performs a middle click. Handshoe Mouse Functions
Three Buttons for Large Size: The Large size of the Handshoe Mouse has three tactile switches corresponding to left, right, and middle mouse clicks. Between the first two buttons is a clickable scroll wheel (slightly smaller than a standard scroll wheel) that performs the middle click function.Handshoe Mouse Functions
Variable Weight: The weight of the Handshoe Mouse can be reduced slightly if desired by removing metal weights housed in a special compartment accessed from the underside of the mouse. On earlier models the cover was directly accessible by removing a screw. Newer models have a small storage compartment with a false bottom. On these models removing the screw securing the false bottom gives access to the weights. The weights are specifically there to facilitate customization. Research by Hippus NV determined the ideal weights for the various sizes. However, if some individuals prefer a slightly lighter mouse, adjustment is easily accomplished. Note: To comfortably handle an object, it needs to have a certain weight. If an object is too light, extensor and flexor muscles have to continuously compensate for this, with the result that these muscles become overactive. This is highly counter productive when one aims to provide optimal relaxation to these muscles.
Wired and Wireless Models: In order to accommodate the widest possible range of working environments, there are both wired and rechargeable wireless versions of the Handshoe Mouse. Note that the Extra Small for the Right hand is only available in a Wired model.
Rechargeable Battery: The wireless version of the Handshoe Mouse uses a rechargeable Lithium battery. In order to optimize battery life it is best to wait to recharge until the blue LED shows via the Scroll Wheel, indicating that the battery is getting low. Doing this will ensure that the recharging cycles are optimized. 6-8 hours of charging will bring the battery back to full charge. As with all rechargeable batteries, with age and repeated charging cycles one may find that the time between charges will begin to decrease. Under average use there should not be significant change for at least several years. Even if the battery completely fails it is possible to continue to use the mouse as a corded mouse. The Rechargeable Lithium battery should only be removed by professionals.

Use Arm Supports - It is recommended that the forearm be supported either by the desk or the arm rest of a chair. Where neither of these are available there may be the possibility of adding a specialized armrest which will provide the support necessary to receive the greatest level of benefit from your Handshoe Mouse.
Position Your Mouse Correctly - If the Handshoe Mouse is positioned too low you will end up reaching down in order to position your hand on the body of the mouse. This INCORRECT POSITION will create an extreme degree of Wrist Extension. Not only will this prove to be very tiring and most almost certainly painful, it will also greatly increase the risk of developing a range of potential RSI. A CORRECTLY POSITIONED Handshoe Mouse will have the hand approaching the body of the mouse level or just above the height the mouse is positioned at, keeping the bend of the forearm/wrist junction to the lowest angle possible. For recommended usage see the Image Gallery
Move the Mouse with Your Arm - Rather than trying to move the mouse with the fingers and wrist (the WRONG way), take the time to learn to move the mouse with your arm. Not only does this reduce many of the risks associated with mouse usage but it also encourages beneficial bloodflow through the arm and hand.
Use a Firm Low-Friction Mousing Surface - In order to optimize movement and reap the greatest benefits from your HandshoeMouse it is recommended to use the mouse on a firm* low friction mousing surface. The design of the Handshoe Mouse transfers a greater amount of weight onto the mouse than with standard mice that people control with just their fingers. As a result, there can be a greater degree of resistance to initial movement. This can result in a "jumpy" movement when either starting to move the mouse or when slowing to accurately target a specific point. These potential issues can easily be addressed by employing a surface which is designed to address resistance. WowPads are a cost-effective way of providing this benefit to your Handshoe Mouse.(* The cushioning on a traditional fabric/textile topped mousepad compresses under the added weight of the hand fully resting on the HandshoeMouse, with the mouse slightly sinking into the pad. This creates additional resistance to movement that combines with the surface friction that is already present with the textile surface.)
For optimal battery life it is generally best to wait to recharge until the blue LED shows via the Scroll Wheel, indicating that the battery is getting low. Generally a 3-hour charge will return the battery to maximum capacity. On models with an On/Off switch - always ensure that the switch is set to ON for charging. If the switch is in the OFF position the battery is totally disconnected and cannot accept a charge.
Avoid Draining the Rechargeable Battery | Fully draining the rechargeable battery can result in a loss of connection between the Handshoe Mouse and the USB Receiver. Should that occur please refer to the troubleshooting section of the included guide or visit the manufacturer's FAQ page.
When first beginning to use the HandshoeMouse you may wish to lower your mouse pointer speed. This is because you have most likely been using your fingers to perform micro-movements of the mouse. Because the Handshoe Mouse is designed to transfer this movement to the larger muscles of the arm you will probably find that the cursor moves too quickly. Lowering the pointer speed will assist in addressing this "jumpiness" that you may experience at first. As you become more proficient and your muscles learn the finer control you will most likely be able to incrementally increase the pointer speed while still retaining your new-found level of control.
