Find more resources, including how to use the software, at www.datasupport.siliconcoach.com Setting up your workspace is very important. You need to capture good video to be able to make the correct decisions when fitting bikes. This section will highlight the important factors when setting up your workspace. Notes:  You should also consult your Specialized Rep as they can get the store design people at Specialized to help you.  The fisheye does not work with HD capture so please make sure you look at the space requirements carefully. CORNEROPTION
This image shows the critical dimensions to the system. The important points to take from this image are:  The cameras must be at least 2.85 m (9’ 4”) from the bike (they can be more then zoom in). 
The critical area in grey is to allow you to easily move around the rider during the fitting process, usually on a rolling stool. 
It is important that the rider/customer can easily see the screen and can be shown what you are doing at why. 1 
The camera height for both cameras is about the height of the top tube. You do not need to set this for each bike, just set it to the height of the top tube of a midsized frame and leave it there. 
The side camera should be inline and at right angles with the bottom bracket. 
The front camera should be looking directly down the length of the center of the bike. The front camera can actually be closer if you are only interested in the lower limb of the rider. Rather than move the camera for different scenarios, the best way to adjust this is use the Zoom feature on the camera. 

Positive points of layout:  Requires minimal floor and wall space.  Semi private space created.  Wires and cables easily concealed.  Cameras may be secured to wall and left in place. Possible challanges of layout:  May be difficult to control the background for the cameras. 2 LONGNARROWOPTION
This image shows another way of setting out the system when space is limited, for example a narrow shop. Notice that camera 1 is actually across the walkway. Positive points of layout:  By creative use of space and pull down screens you can create a dedicated space for the fit system and not impede too much on floor space and wall display space.  The 2 cameras are more than 3 m from the bike and are fixed to walls and then using the camera’s zoom the image of the rider is magnified back to full screen. Camera 2 is even across the other side of the main walkway attached to the wall which is alright as you only need about 5 seconds of video. You just needs to make sure no one walks in front of the camera during capture; even if they did it’s easy to just do a re‐
capture. Possible challanges of layout:  People may walk in front of camera 1, however as you only need to capture for no more than than 10 seconds this can be managed. Notes:  The space should look clinical, precise and professional; too much clutter will spoil this experience for the customer.  The bikes and display cabinets are for illustration only and could be in many other places and there could be many more of them. 3 Cabling for HD There are a few cabling options and your choice depends on the capture technology and the distance between the camera and the computer. Using two Blackmagic Intensity Pro PCI cards in a computer tower with <20m between the camera and the computer. Note: If you are cabling within walls you need special HDMI cables that are up to code for internal routing. Using two Blackmagic Intensity Pro PCI cards in a computer tower with 20 ‐50m between the camera and the computer.

(Source for Cat5 extender is http://www.bhphotovideo.com then search for “Port HDMI Extender Over Single Cat5” ) Lighting Lighting is a critical and often overlooked part of your setup. The quality of the light greatly influences the quality of your image. The software cannot compensate for bad video. A blurred image is usually the result of incorrect camera settings, bad lighting, or both. Type of lights You need lights that do not flicker as the image will flicker on the video clip as well. Fluorescent lighting can cause a lot of flickering. You also need lights that shine as closely as possible to white light, some lights shine light with a yellow tinge. You may still get good images for analysis but everything may look a bit yellow. It is important not to mix your lights, if you do the Auto Brightness feature on the camera will not be able to compensate for the different shades of ‘white’ emitted from the different lights. Position The lights need to create a diffuse lighting pattern that does not create shadows or light burn (where the lights cause parts of the skin to look ultra‐white on the video). You will need lights shining directly on the fitting area and also indirectly on the area by bouncing the light of the roof, walls etc. If you are in doubt about what you should do you should contact your local photography and video expert. Intensity Good lighting does not always mean the most intense lights; a few well‐placed lights positioned as outlined above can work just as well. Intense lighting will cost more in power, create harsh contrasts in the video image and will also create a lot of heat in the area. Reflection Be careful not to have any lights shining on highly reflective surfaces; it causes very bright spots on the video image and the camera will darken the whole image to try and reduce the light ‘burn’. Safety Safety in the space and during the fitting process is very important. Even people with good balance and mobility can find cycling on an indoor trainer an unnerving experience. A signed non‐liability document may be needed in some countries. 5 Setting Up Your Cameras The camera is one of the key components of the system and as such setting up the camera is very important. If you capture poor video there is very little the software can do to improve it so you are left with an unclear or distorted image that will greatly decrease your accuracy. Level and at right angles to bike The cameras must be level in all planes. When you use the drawing tool to draw a horizontal line it assumes the background is also horizontal. You could quite happily make measurements and draw reference lines on the screen, but if the image in the background is not correctly aligned with the camera your conclusions will be wrong. The camera must be: 
Level side to side 
Level forward to back 
At right angles to the plane of movement ‘Right angles to the plane of movement’ means either directly to the side of the cyclist or directly in front. For BG FIT analysis, the common views are directly from the side and directly from in front (Z‐plane). Mounting/Security Experience has told us that it is very important to securely mount your camera. The first reason is that it will not get knocked out of line as easily and the second is that it dramatically reduces the number of cameras stolen out of stores. Height Generally for biomechanical analysis, the camera should be at approximately half the height of the subject of interest (95 cm). If you are looking at the whole body on the bike the camera should be set at about the height of top tube. You do not need to set this for each bike, just set it to the height of the top tube of a midsized frame and leave it there. If you were just looking at the lower limbs, the camera should be about knee height. The camera should also line up with the center of the bicycle. Camera settings Modern cameras are very good at automatically adjusting to different light conditions but there are a few of things you can do to improve on that even more. As the default camera settings are out of our control, you must set these as outlined below or you may have low quality video. These settings are similar for all camcorders. (NOTE: Refer to the camera manual to make the following settings). DATE AND TIME: Set the date and time. For more information refer to the camera manual). SHUTTER: A fast setting means the shutter is only open for a very short time; this means there is less body movement while the shutter is open and therefore less blurring. If your image is blurred it is not a function of the software but a function of the camera settings and lighting (you cannot correct for blurring in the software). However, the disadvantage of a fast shutter is that there is less time for light to get onto the camera sensor and this causes dark images. To compensate for this you need lots of light. 6 Some cameras use a setting called Sports Mode instead of a manual shutter setting. Sports Mode gives you the fastest shutter speed it can for the given light, therefore to increase shutter speed you need to increase the light. For more information see the camera manual. FOCUS: The focus control is usually able to be set to manual or automatic. Automatic will usually work fine except when someone walks between the camera and the fitting area and thereby changes the focus for an instant. This may occur if you have your camera mounted some distance from the bike, such as across a walkway. In these circumstances it is better to set it to manual and then manually adjust the controls to get a clear image. For more information refer to the camera manual. DEMO MODE: Demo mode usually starts up about 20‐ 30 minutes after starting the camera and you will see the screen start to do all sorts of strange things. For example it may start shaking, the image make go black and white, then sepia, then blurry, then shake again and so on. You do not want this happening when trying to video a customer but unfortunately most cameras come with the Demo mode turned on. For more information refer to the camera manual. WHITE BALANCE: Our eyes are very good at adapting to different lighting conditions such that when there are many shades of near‐white we perceive them as pure white. Cameras however are not so accommodating and different light conditions such as outdoor, fluorescent, halogen, all give slightly different shades of near white. Sometimes the video images look yellower (warmer) or bluer (cooler). Your camera has auto adjustment to accommodate for this but you can help it by telling it if the video situation is indoor or outdoor. For bike fitting it is usually going to be indoor but if your space has a lot of outdoor lighting coming on to it, the outdoor setting may be best. You need to try both and see which looks best in your situation. For more information see the camera manual. Background It is important that the background the camera sees is as neutral as possible; do not use anything reflective such as glass. A plain grey, blue or green background is best, try to avoid black or white as they create a lot of contrast and may make your image too dark or too light. Also try to avoid a lot of lettering or pictures in the background, it will cause confusion and make it harder to find the key points on your customers’ body. Background sheets are not expensive (about $50 USD) and can be found by typing ‘chromakey screens‘ into a Google search. Other Things to Consider Read through the following list of miscellaneous things to consider Privacy/Promotion This analysis system will attract a great deal of interest in your store and is an excellent sales promotion tool; however, you must balance this with the privacy of the customer. Make sure they feel comfortable not only riding on an indoor trainer and being filmed, but also with the amount of privacy 7 you provide. Power You will need power to the computer and monitor but also remember the cameras also need power and could be 2‐5 m away from your computer and power box. You must be careful running power cables across an area where customers are going to walk. The best option is to get your electrician to wire in power plugs exactly where you need them. Make sure you have your layout design finalised before you do this. Computer position A desktop box can be securely hidden away under a bench but you will need space on top for the screen, keyboard and mouse. You may also need a space for your tools. Computer screen position The computer screen position is very important as it is not only used for your analysis but also to convey your results and thoughts to the customer. It is critical to the customer’s experience that they can see the screen and see what you are doing and why. Keyboard and mouse position The keyboard and mouse position needs to be within easy access as you will be using them a lot, especially the mouse. The system is designed to minimise keyboard use but you will still need to type in the customer information at the beginning of the session and at other times when you many need to type results or extra comments. Cables Cables can be dangerous and make the workspace look disorganised and this creates an impression of lack of precision. Where possible, cables should be wired into fixed structures by an electrician. Where this is not possible they should be secured and covered with a rubber mat or something similar. You will need power cables and long video cables (these connect the camera to the computer). Professional workspace It is very important to present a professional workspace at all times. It conveys to the customer that this is a high precision work place and it will increase their confidence in your recommendations. Keep all paper material to a minimum, do not put parts and tools on the bench near the screen, keep cables hidden away, and keep the space clean and tidy. The design of the whole fitting area has a critical role in creating a feeling of confidence in your ability to correctly fit bikes. Colors, lighting, pictures, stock etc, properly positioned, all play a role in creating this atmosphere and a positive retail experience for the customer. 8
