of Kinesis PD7DXT:

The DXT Ergonomic Precision Mouse is a compact
ergonomic mouse which has been expertly designed
by a team of leading UK physiotherapists and
ergonomists. The DXT precision mouse promotes a
neutral (more vertical) wrist posture while
allowing the hand to work in the precision grip.
It is the only compact ambidextrous ergonomic
mouse that has been designed to use the
precision movements of the hand.

Features of Kinesis DXT Precision
Mouse:

• Ergonomic Relaxed Neutral Wrist
  and Hand Position – The design
  of the DXT Ergonomic Mouse enables the
  hand to work from a relaxed position
  reducing the tension on the soft
  tissues. In addition the vertical design
  avoids extreme twisting of the forearm
  helping to increase comfort.

• Precision Grip for Accurate
  Navigation – Similar to a
  pen grip the DXT design allows for
  accurate navigation. Small muscles
  and joints of the fingers have
  higher processing abilities for
  movement and sensation than other
  larger body parts. The large muscle
  groups of the shoulder are adapted
  for power and larger ranges of
  movement whereas the smaller muscle
  groups of the hand are adapted for
  finer, precise movements.

• Instantly Switches Between Right
  and Left Hand
  • By pressing a single button the DXT instantly switches between right and left handed use. It does NOT require primary button function change in the Operating System, regardless of left or right handed use.
  • This unique feature allows the user to spread the mouse usage throughout both right and left hands with relative ease. It also enables users with an injury to the dominant hand to easily switch to their non-injured hand and continue to work effectively with minimum impact on productivity.

• Compact Design
  • The DXT Precision Mouse’s unique compact design fits a large range of hand sizes.
  • Unlike other ergonomic mice the DXT Precision Mouse’s compact design is ideal for laptop and travel use.

• Fits Most Hand Sizes
  – Accommodates Both Large and Small
  Hands.

• Grasping the DXT
  • Start by placing the tip of the ring finger over the black plastic triangular area beneath the bottom click button. The remaining finger tips and thumb will naturally position themselves on the first half of the front and back mouse surfaces, respectively, with the pinkie finger tucked in. The fingers should be comfortably curled (e.g. holding a pen) versus extended or lying flat.
  • The resulting hand and finger posture facilitates precision movements and avoids the fingers being placed one upon the other and coming into contact with the cable (Figure 1).
  • It should be noted that the body of the mouse is not placed parallel to the side of the keyboard but at an angle to the side of the keyboard as shown in Figure 2.

• Research Based Concept – why it
  works – Using a mouse to
  navigate the cursor and activate icons
  is a precision task that demands a high
  degree of accuracy. Scientific research
  shows that designing pointing devices is
  best accomplished by basing the concept
  on the design of the human body, since
  this results in the most efficient and
  accurate moving of the cursor.
  • Small muscle and joints in the fingers have higher information processing abilities for movement and sensation than other body parts.
  • The upper limb has evolved to be agile and strong. In order to deliver both agility as well as strength each joint and associated muscle groups of the upper limb have developed their own purpose and function. The larger muscle groups that operate the wrist, elbow, and shoulder are adapted for power and a larger range of movement. The smaller muscle groups that operate the fingers and thumb have more agility.
  • When all the parts work in synergy, both movement range and agility can be maximized. What is required in computer mouse design, therefore, is to enable the best use of all joint and muscle elements of the upper limb.
  • This requirement is not achieved by moving control of the mouse from the smaller muscle groups to the large ones (as in many so called “truly ergonomic” mouse designs) but rather in using the small muscle and joint groups in addition to the large ones.
