HandshoeMouse or Handshoe Mouse

The HandshoeMouse (often referred to as the Handshoe Mouse) from Hippus is designed to fit your hand like a glove - no gripping, no pinching, no stretching fingers. The unique shape of the mouse allows your hand and fingers to relax while mousing, helping to reduce the risk of RSI. The design also provides full support of the hand and wrist, and comes in three sizes for the right hand. The recommended usage for this mouse is on your desk with your forearm fully supported by the desk or arm support of your chair. There are two buttons with scroll wheel (three on the large model). The optical tracking is 800 DPI and no software is required - it works plug and play. Available in wireless (black only; USB cable charges battery) or wired (black, white and translucent clear models).

• Reduces Wrist Pronation: The HandshoeMouse is angled downward from the thumb rest to the opposite side of the mouse at about a 20° angle. This slanting of the mouse has been shown by research to reduce wrist pronation, which can contribute to wrist pain and injuries. Even this slight slanting of the mouse can have a significant impact on the wrist over longer periods of time and is one of the main design requirements incorporated into the HandshoeMouse.
• Reduces Wrist Extension: Another risk factor that the HandshoeMouse 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 rear of the HandshoeMouse, however, provides such support through the elongated 'ramp' that allows the hand and arm to gradually incline from the desk to the front buttons, thereby preventing the wrist from excessive extension. It is this specially designed elongated 'ramp' at the rear which helps reduce wrist extension, and by extension, common RSI problems.
• Reduces Hand and Arm Fatigue: The HandshoeMouse's design requires that the user's work surface be large enough to allow full movement of the arm when moving the mouse while the arm rests on your desk. It is important to use this mouse with your arm resting on the work surface, since the mouse should be moved primarily by arm movement and not hand or wrist movement. In this way, both hand and arm can be used most advantageously, thus reducing any excessive fatigue generated from improper or ill-advised hand and arm movements. Consequently, proper use of the mouse is just as important as proper positioning of the hand on the mouse, since it is both these aspects in conjunction that will give maximum benefits to the user. 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 most economical and ergonomical way.
• Reduces Shoulder and Neck Injuries: Slanting the mouse by about 20° can reduce not only injuries due to pronation but even those associated with the neck and shoulders.

• Sculpted Body Shape: The sculpted design of the HandshoeMouse's body allows for the hand to comfortably rest on the mouse without having to grip or pinch the sides in order to move it. In addition, the mouse slants slightly from the thumb groove to the small finger's edge by about 20°. It also inclines downward towards the elongated rear of the mouse to reduce wrist extension. All these design elements are combined in such a way as to provide maximum ergonomic benefits while maintaining an attractive and stylish look.
• Three sizes for both left and right hands: Because the HandshoeMouse is designed to fit your hand, it must be able to accomodate different hand sizes and come in both a left and right hand version. Thus there are six different mice models available, with hands sizes (left and right) corresponding to hands measured from the tip of the ring finger to the wrist crease in large (210 mm or 8.25"), medium (190 mm or 7.5"), and small sizes (170 mm or 6.75"). Note: we currently stock right-hand sizes only - left-hand sizes are manufactured on demand and cost up to four times the amount. To determine which size is appropriate for your hand, see the HandShoeMouse sizing chart.
• Three colour options: The HandshoeMouse is available in white, black, or transparent colours (current stock is only available in white or black, however).
• Wired and wireless models : In order to accomodate the widest range of working environments possible, there are both wired and wireless versions of the HandshoeMouse. The wired model has a cord that plugs into your computer at one end (standard USB port) and into the mouse itself at the other end (smaller USB port). The wireless version's batteries can be recharged using the USB cable.
• Two buttons for small and medium sizes: Both small and medium sizes of the HandshoeMouse 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).
• Three buttons for large size : The large size of the HandshoeMouse has three tactile switches corresponding to left, right, and middle mouse clicks. The third switch requires a lighter tactile force to activate than the other two standard switches.
• Replaceable rechargeable battery : The weight of the HandshoeMouse can be lessened slightly, if need be, by removing certain metal and plastic weights housed in the interior of the mouse. The weights located in the outer chamber in the underside are specifically there to allow the user to reduce the weight of the mouse. Research by Hippus NV determined the pivot weights for the various sizes, although they do not actively promote this feature of the mouse. However, if some users prefer a slightly lighter mouse, then it is very easy to just remove a few weights.

  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.
