General Information

1. Is a DataHand ergonomic keyboard more comfortable than other keyboards?
Yes. No other keyboard is as adjustable to fit the size and shape of each person's hands—even if a person's hands are different from each other! While other keyboards require finger and hand movement to find lineally located, ergonomically inadequate key positions, the DataHand keyboard places all the keys within a short reach of the tips of the fingers. This design makes keyboard work more comfortable, less stressful and more productive. When finger travel distances are reduced, key activation forces can also be reduced. On the DataHand keyboard, operators do not tend to use more force than necessary as their fingers move among the keys. The key activation movements are gentle, quick, and easily differentiated. Each key has a different feel and movement direction. These factors all add up to a keyboard that is more comfortable, less stressful, and less demanding of strenuous effort to operate.

2. Is a DataHand ergonomic keyboard more healthful than other keyboards?

Yes. Improved comfort, reduced chronic workload, reduced upper body musculoskeletal involvement, and an intrinsic mouse (accessible without hand movement) result in a more healthful experience offering lower risk of injury. Because the hand is ergonomically supported, stress to the arms, wrist, and upper body is avoided. On the DataHand keyboard, work is done by the fingers alone, without any hand, arm, and wrist movement. These findings have been proved through independent, peer reviewed, and published studies and also through many compelling user testimonials. For further detail, please click here to see the Studies section or click here to see the Testimonials section.
The DataHand ergonomic keyboard is not a medical device and no medical claims are made on its behalf. Through improved design, it simply reduces the stress factors incumbent with the traditional keyboard.

3. Does a DataHand ergonomic keyboard reduce finger and hand workload?

Yes. Work is defined as force times distance (W = F X D). The DataHand ergonomic keyboard reduces both variables of the work equation, namely force and distance. The forces required to activate DataHand keys are much less than the forces required on traditional keyboards. The keys on other keyboards require an increasing percussive force curve whereas DataHand keys rely on low-force magnetic switches with a decreasing or inverse force curve. A completely different more user-friendly touch is enabled. Once the position of the keywells are properly adjusted, many of the keys are no more than 0.1" (2.5 mm) away from the finger tips, depending on the size of the fingers. All keys require no more than approximately 0.5" (1.25 cm) finger movement from their home position in the center of the keywell. This minimal movement is true for mouse operation as well! With the two variables of the work equation in mind, ergonomists have described the DataHand ergonomic keyboard as a minimal force and minimal motion keyboard.

4. How adjustable are DataHand ergonomic keyboards?

DataHand keyboards are more adjustable than any other keyboard on the market. The DataHand design offers an appropriate range of adjustability in every plane. Only the distances between fingers are not adjustable. Two sizes of palm pads are available (small and large). The palm pads, keywell sizes, and the DataHand range of adjustment were all designed to comfortably fit roughly 90% of adult hand sizes. The individual hand modules can be positioned to fit the preference and comfort of each user. Some DataHand users work on the provided LapLander™ shipped with each DataHand keyboard while others place their DataHand keyboard on a desk, in a keyboard drawer, or even on the arms of a specially designed ergonomic office chair. Such a chair is available as an accessory from DataHand Systems. Some very large keyboard operators place the two hand units as much as three feet apart on opposite arms of a specially designed chair.

5. Does a DataHand ergonomic keyboard really offer the lightest key touch available?
Yes, ANSI standards for key activation forces are between 50-60 grams. Key forces on the DataHand keyboard are less than half this force standard. DataHand keys only require 18-22 grams of force, and all DataHand keyboards are tested for standard compliance prior to shipment. How is such a light key touch possible? Most other currently manufactured keyboards are activated by membrane based circuitry. The DataHand system relies on a patented low-force magnetic switch design unavailable on any other keyboard on the market. Remember that the DataHand Ergonomic Keyboard key force is only one half of the story when it comes to chronic workload—the other variable is the finger travel distance required for key activation. For those with special needs because of serious injury in the past, the key forces on the DataHand keyboard can be reduced below the 18-22 gram range. This modification is available as a special option. Individuals experiencing chronic pain from keyboard work should inquire about this option.

6. How are DataHand finger motions less repetitive?
On other keyboards, each key requires a repetitive downward keystroke. All keys require the same downward, percussive finger movements for activation. On the DataHand keyboard, only one of the five keys surrounding each finger requires a downward key activation movement. The other four keys surrounding the fingertips require movements to the north, south, east, and west. In this way, the DataHand keyboard distributes typing motions in five tactually distinct directions. Rather than repeating the same undifferentiated downward, percussive motion, the different keys surrounding each finger become associated with five different, much more gentle, shorter, less stress inducing movements. In addition, on the flat keyboard and other keyboards based on the basic flat keyboard paradigm, workers tend to use more force than necessary to activate the keys. This tendency compounds and intensifies repetitive motion aggravations. On the DataHand keyboard, the tendency to use excessive force is eliminated. Applying more force than necessary is actually difficult on the DataHand keyboard. In contrast to the common "key pounding" pattern on other keyboards, the DataHand system enables users to work gently and quickly, using light touches on the keys.

7. How do DataHand ergonomic keyboards reduce carpal tunnel involvement?
Since keystrokes on the DataHand system are distributed among five different motions, some of the motions do not involve tendons passing through the carpal tunnel. The Down, North, and South keys require flexor and extensor muscles of the fingers and hands for their activation. These muscles utilize tendons that travel through the carpal tunnel. On other keyboards, all keystrokes rely on carpal tunnel involvement. On the DataHand keyboard, the East and West keystrokes use intrinsic muscles of the fingers and hands which do not require carpal tunnel involvement. Even the keys requiring carpal tunnel involvement on the DataHand keyboard offer low forces and short finger travel distances. These two factors greatly reduce stresses through the carpal tunnel. Because the wrist is supported in a straight position on the DataHand palm pad, the tendons moving through the carpal tunnel do not become crimped and irritated. The reduced chronic workload associated with DataHand use is likely to allow the reduction of global swelling in the hands—if this aggravation has resulted from previous work on other keyboards. In sum, the DataHand ergonomic keyboard is more friendly to the carpal tunnel. Documented user experience supports this conclusion.

8. How does a DataHand ergonomic keyboard work?
DataHand keys are distributed in finger modules surrounding the fingertips of the operator. The position of these modules can be adjusted to fit varying hand shapes and finger lengths. The keys are activated through low-force magnetic switches requiring minimal finger movement and forces for their activation. Each finger module has 5 keys: Down, North, South, East, and West. Four such finger modules and one thumb module make up the key switch arrangement for each hand. Letters of the alphabet are presented in the default or normal mode following the standard QWERTY keyboard layout, with only four modifications. For example, the left little finger controls Q (north), A (down), and Z (south), just as it would on a traditional keyboard.
Numbers and symbols are accessed in NAS (Numbers and Symbols) mode, entered by pressing the down switch on the right thumb. This Thumb-Down switch is a two level switch with shift on the first level and shift lock on the second level. The two levels of this switch are perceptibly differentiable by feel. When locked, the NAS mode light remains on even when the finger is removed from the switch.
The lock would be used for extended entry of numbers with both hands. (The additional ten-key option allows all the numbers to be available on the right hand.) Capital letter shifting in the normal or alphabetic mode is accessed via a downward motion of the left thumb. The second stage of thumb travel locks the keyboard in CAP shift lock. An associated light just above the left thumb module goes on when CAP shift is locked. The mouse and function mode is entered via an upward movement of a key on the right thumb. This converts both index finger keys into mouse movement keys. Further explanation of the DataHand mouse function is provided in the Mouse section of this FAQ document following below.
At any time, the keyboard can be returned to normal mode by pressing the normal mode key using an upward movement of the left thumb. A colored light on the right hand unit always indicates the current mode. In the future an accessory will be available to audibly announce mode changes. The cornerstone of the DataHand design is the minimal force and minimal motion required to perform work. This greatly reduces fatigue and increases productivity.

9. Is a DataHand ergonomic keyboard faster than other keyboards?
Yes. A statistical analysis of seven separate productivity studies has demonstrated a 16 +/- 9% average typing speed improvement over traditional keyboards by day 30 of DataHand use. The confidence interval of this analysis is 95%. In these studies, 75% of users enjoyed an increase in typing speed. Many of the remaining 25% in any average group of workers will typically reach their prior flat keyboard speed and improve on it during a second 30 day period. People require different amounts of time to learn the different touch of the DataHand keyboard. As it is with many skills, some people learn very quickly. Others need more than average amounts of time.
One worker achieved 90 wpm in less than an hour and others have achieved their flat keyboard speed in a couple of days to several days. The cited productivity studies were independently conducted at several corporate worksites where DataHand Systems' Corporate Training Program was used to train workers in DataHand operation. Clearly, individual learning processes vary. Please see the Learning Curve section of Frequently Asked Questions that follows.

10. Is a DataHand ergonomic keyboard more accurate than other keyboards?
Yes. An increase in typing accuracy is both an expected result of the design and also a real benefit of using the DataHand ergonomic keyboard. Float error (errors caused when unguided fingers float erroneously to the wrong key), which is a major cause of error on the flat keyboard, is reduced on the DataHand keyboard. While DataHand does not automatically enable people to become more dexterous, it does reduce factors that make errors easily possible. The differentiated tactile feel of the keys and distinctly different direction of the activation movements enables the typing process to be managed more by the nerve endings in the tips of the fingers. The brain does not have to learn many complex flight pattern combinations necessary to direct the fingers between and among all the required key sequences. Not only are finger movements simplified, but also hand movements are eliminated entirely. Long finger reaches needed to get to the numbers and symbols on the traditional flat keyboard are also eliminated.
Rather than looking and reaching to activate the numbers, as operators do on a traditional keyboard, DataHand keyboard users simply enter NAS (Numbers and Symbols) mode and type numbers and symbols directly from the home row. The down keys in the center of each keywell are the equivalent of the home row of keys on the traditional flat keyboard. The Function Keys are used similarly. To employ the Function Keys on a DataHand keyboard, users simply enter Mouse and Function mode and touch type the Function keys in the same way alphabetic keys are typed. Of all the accuracy promoting factors, the most important may be the differentiated feel of the different keys. On traditional keyboards all keys feel the same—all are downward keystrokes at a particular point in an undifferentiated plane. On the DataHand ergonomic keyboard, each of the five keys surrounding each finger feels different.

11. Who buys DataHand ergonomic keyboards?

About 75% of DataHand customers are "Ergonomic Clients;" the other 25% are "Productivity Clients." Individual ergonomic clients come to DataHand Systems seeking relief from the pain experienced from working on other keyboard products. Some clients are pro-active wanting to prevent pain and discomfort in the future. However, most are desperate for a keyboard concept offering pain relief and comfort. Most spend 6+ hours per day keyboarding and mousing; many are computer professionals with an existing chronic repetitive stress injury such as carpal tunnel syndrome or tendonitis. Many are contract or self-employed computer programmers who use the DataHand ergonomic keyboard to protect their hands from debilitating and career threatening injuries.
The corporate ergonomic clients of DataHand Systems typically have a growing group of employees with keyboard and mouse-related injuries. They use DataHand ergonomic keyboards to close keyboard-related workers compensation claims, reduce employee re-training costs, and to reduce employee rehabilitation costs. With OSHA ergonomic standards imminent in the United States, DataHand Systems is attracting increased interest from corporate Workers' Compensation claims administrators.
DataHand productivity clients include corporations wanting to enjoy the improved speed, accuracy, and reduced fatigue associated with the DataHand ergonomic keyboard. These clients include high volume data entry applications such as bank item processing departments, post office mail processing departments, accounts receivable departments, and call centers. Proven productivity improvements make the DataHand return on investment quite attractive to these customers. For further information on Internal Rate of Return and Return on Investment calculations from existing customers, please contact the DataHand sales department or see a summary of a variety of corporate productivity studies in the Studies section of this website. Prospective analyses can also be made using wage and other data provided by a potential corporate customer.

12. What is the return on investment generated by a DataHand keyboard?
The investment in a DataHand ergonomic keyboard includes the product cost and the time required to reach previous baseline typing speed and accuracy. The return on this investment is very powerful. Users report almost immediate improvements in finger and hand comfort, reduced typing fatigue, and reduced pain due to keyboard related injuries. Often, this comfort and pain relief comes after trying other alternative keyboards and many other types of remedies.
The human return on investment translates into lower health costs, less lost work time, and lower Workers' Compensation costs. These savings are in addition to direct savings from more productive, less fatiguing computer keyboard work. A DataHand ergonomic keyboard offers a very unique and well-proven alternative to all other keyboard designs and, for many people, offers the over-riding value of protecting their livelihood.


Learning Curve

1. Can anyone learn a DataHand ergonomic keyboard?

Yes. The DataHand ergonomic keyboard is organized like a traditional keyboard. At first it may look daunting but within minutes you will understand the key layout, modes, and design. The finger assignments are the same as they are on a traditional keyboard—except for four letters, which must be relearned. These four keys correspond with the diagonal movement of the index fingers on the flat keyboard (the B, T, N, and Y keys).
On the DataHand keyboard, the thumbs do more than simply operate the spacebar; they are given multiple responsibilities, consistent with their competence. Both the finger and the thumb key assignments are intuitive and easy to learn. A different keying motion must be learned, but the learning time spent pays off in improved comfort, relief from risk of injury, less fatigue, reduced pain, and greater productivity.

2. How quickly can a typical person learn to work on a DataHand ergonomic keyboard?
Heads up templates are available for learning the keyboard layout and on average, DataHand keyboard users report they have needed a short amount of time to become familiar with the keyboard layout. Statistical studies have shown that within 30 days the DataHand users attained at least 7% improvement to their previous baseline typing speed and accuracy. Touch typists may transition to the DataHand ergonomic keyboard faster than do "hunt and peck" typists.
Beginning typists can learn to type on a DataHand keyboard faster than they can learn to type on the traditional keyboard. Many design factors contribute to making the DataHand ergonomic keyboard easier to learn. The tactile feedback available from the differentiated feel of the DataHand keys is a major factor in facilitating learning. Nevertheless, some time is needed to learn the different and softer touch and feel required to work on the DataHand keyboard. Remember, your current keyboard skills were learned, usually, long ago and polished over many years. Your return on the DataHand learning period will be immediately improved comfort, pain relief, and increased keyboard efficiency and accuracy.

3. What Individual buyer training resources are available?
Your DataHand ergonomic keyboard will arrive with a training manual developed specifically to facilitate your DataHand experience. View Training Manual

4. What training resources are available for corporate buyers with many workers?
The two options include a "Train the Trainer Program" and a "Corporate Training Program." With the Train the Trainer Program, DataHand trainers will train a company's in-house trainers to become a Certified DataHand Ergonomic Keyboard Trainers. This can take place at our main office in Phoenix, Arizona or at the client's location of choice. With the Corporate Training Program, a DataHand trainer will train up to 10 employees per session on the DataHand Ergonomic Keyboard. This takes place at the client's office(s) and training is tailored to the company's applications.


Mouse

1. Where is the mouse on a DataHand ergonomic keyboard?

The DataHand mouse is built-in right at the tip of the operator's index fingers on the DataHand keyboard. One finger can be set to move the mouse slowly, and the other finger can be set to move it more quickly. Or, both can be set to the same speed. The speed of each mouse control module is independently adjustable. The DataHand mouse is shipped as a two-button mouse setting, but it can be set up as a three-button mouse. By use of a switch on the middle finger of the left hand and the third finger on the right hand, the mouse keys can be switched between cursor movement and mouse movement.

2. How is the DataHand ergonomic keyboard's mouse controlled?
The mouse control is based on the same principles as the DataHand ergonomic keyboard; minimal finger movements and minimal forces are required, and the operator's fingers do not need to leave the home row of keys. The upper body musculoskeletal involvement commonly necessary to operate traditional, accessory mice is eliminated.
When mouse mode is entered by activating the Function/Mouse mode switch on the right thumb, the keys surrounding the index fingers become active for mouse or cursor movement. DataHand mouse movement emulates a traditional mouse—but with the unique DataHand ergonomic benefits. When used together, the speed of the two fingers is additive, offering a third speed. To left click, press the left index finger down key and for the right click, press the right index finger down key.
To leave mouse mode, the left thumb up switch is used to return to normal mode. The operator's fingers do not need to leave the home row of keys to operate the DataHand mouse! On other keyboards, movement of the hand back and forth between the keyboard and the mouse is both time consuming and stressful. Both the hand work involved in mouse work and hand movement between the keyboard and the mouse are significant sources of upper-body stress. On the DataHand keyboard, such hand movement, like all other hand movement is eliminated.

3. What mouse platforms are supported with a DataHand ergonomic keyboard?
PS/2 (6 Pin) and Serial (9 Pin) mouse connections are available. Adapters are available for Macintosh PS/2 to ADB or USB, PC USB and SUN. When ordering a DataHand keyboard, simply specify a mouse connection (PS/2 or Serial) and adapter if required.


Key Layout

1. Is a DataHand ergonomic keyboard organized like a standard keyboard using the QWERTY key layout?

Yes. Only the letters B, T, N, and Y are assigned to different fingers than they are on the traditional flat keyboard (on the DataHand keyboard, B, T, N, and Y have to be moved to a different place to fit into the DataHand five-keys-per-finger design). The thumb key assignments are arranged in an intuitive, easy to learn layout.

2. Is a Dvorak key layout available?

Yes. The DataHand Professional II offers a Dvorak key layout option for an additional fee. The upgrade includes firmware that allows you to switch freely between the Dvorak and QWERTY layout as desired. The upgrade includes the Dvorak and QWERTY firmware, DataHand key module templates, and both Dvorak and QWERTY training templates.

3. What do the thumbs control on a DataHand ergonomic keyboard?
The left thumb keys are: Return/Enter, Shift and Shift Lock, Tab, Control, and the Normal (alphabetic) Mode Key. The right thumb keys are: Backspace, Alt, Numbers/Symbols Shift, and Numbers/Symbols Lock, Space, and the Mouse/Function Mode Key.

4. Are the keys re-mappable?

Yes. The user following instructions in the User's Guide can change most keys on the DataHand Professional II. Others can be changed using software. A list of available programs can be provided by sending e-mail or calling DataHand Systems. Some of the programs are freeware, and others are shareware.

5. What is the difference between the DataHand Personal Edition and the DataHand Professional II?
They are the same except the DataHand Professional II offers re-mappable keys, macro programming capabilities.

6. Can macros be programmed?
Yes. The DataHand Professional II offers macro-programming capabilities. Approximately twenty macros, each with five keystrokes, can be programmed.

7. Is the DataHand ergonomic keyboard a chorded device?
No. DataHand keyboards are not chorded. Chorded keyboards rely on multiple simultaneous keystrokes to type a single letter. The DataHand ergonomic keyboard emulates a traditional keyboard and mouse—one keystroke per character.
