A mean resting height should also be determined – which is the height to which the screen/keyboard resets after a certain period without use. Considerations include the distance between the keyboard and the front of the shelf, and its angle and, whether it is the monitor or the keyboard that moves to make adjustments. The positioning of input devices such as keyboards, barcode scanners and card readers can be planned for maximum efficiency and most intuitive and comfortable use.Printers can be positioned to provide output close to the user’s hand, so they can easily see a print out and don’t have to bend or reach up or down.Positioning of speakers – for maximum audibility for the majority of users, taking into consideration the ambient noise of the kiosk environment.Screen angling – aiming for maximum visibility for the majority of people, within the confines of the ambient lighting in the kiosk environment.Once these parameters are understood, specific design points can be engineered, including: Kiosks are designed for general purpose access and Dreyfuss’ anthropometric guides help us to address the extremities of parameters such as likely maximum and minimum user heights, in order to set appropriate mid-points. It offers a set of design guidelines rather than rules. The Dreyfuss approach to ergonomic design is about having a point of reference. These standards must be addressed, but the Dreyfuss principles are widely accepted as being more personalised, simplified, visual and graspable.

There is also an ISO standard (9241) for ergonomics, including tactile and haptic responses. The Dreyfuss anthropometric standards are still extensively used, and are one of the foundations on which Neo designs its products. Henry Dreyfuss, who was a 20th century industrial designer, greatly advanced the understanding of, and standards for, good ergonomic design. Cognitive ergonomics is concerned with mental processes and is used in the design of information. In the case of a kiosk, which will be used by a wide range of people, it is concerned with designing the best fit for the widest range of users. Good anthropometric design ensures a good fit between the user, the equipment and the environment. The analysis and understanding of these access variants is called Anthropometrics, and understanding the principles is crucial to designing kiosks with universal accessibility. The users may never have accessed a kiosk before, they may have physical disabilities or impairments, and they may be using the equipment under a whole range of light, noise and weather conditions. Interactive touchscreen kiosks are squarely in this category, being designed for interaction with humans, allowing us to input and receive information in a range of formats, and generally in a public environment. People wanting to access the services will come in a range of sizes and abilities and will need to intuitively understand how the device works first time. You don’t have an opportunity to train the user.You can’t pre-determine the physical attributes of the user and.The measurements will be tested against a validated 3-dimensional digitizer (MicroScribe 3DX).When you are designing a product to provide self-service: We will also develop computer graphics tools for indirect anthropometric measurements in a three-dimensional head model (or polygonal mesh) including linear distances currently used in anthropometry. In this paper we will statistically evaluate and validate a current three-dimensional image-based face modeling technique using a plaster head model. In this paper we will focus on development of indirect 3-dimensional landmark location and measurement of facial soft-tissue with light-based techniques. One can find in the literature a variety of methods to generate 3-dimensional facial images such as laser scans, stereo-photogrammetry, infrared imaging and even CT however each of these methods contain inherent limitations and as such no systems are in common clinical use. Currently, two-dimensional photographs are most commonly used to facilitate visualization, assessment and treatment of facial abnormalities in craniofacial care but are subject to errors because of perspective, projection, lack metric and 3-dimensional information.
