Jill on the Beach
Friday, August 21st, 2009
Do you like being on the beach? I guess so and so is Jill.
Beside the fun part of it, you could see in the video the precise capabilities of Jill (the sister of Jack) to use her fingers in a virtual environment. This is actually important when simulating difficult assembly situations in which precise grasping are an issue.
Using the digital human model Jill (… and of course Jack) you are able to validate and optimize your manual assembly processes already during the assembly planning.

Jack in Space
Monday, April 13th, 2009
Recently I wrote about the digital humans Jack and Jill from our digital manufacturing solution Tecnomatix. You might be interested in some actual customer stories and the value they get from the technology. Here you go.
USA-Space, a subcontractor to NASA, uses Jack to simulate the assembly of the Orion crew vehicle. The Orion crew vehicle is part of the Constellation Program to send human explorers back to the moon. They are using virtual reality (VR) technologies to analyze the ergonomic situation during the assembly process of the crew vehicle. Using a motion tracking camera system, they are able to bring the motions of real people into the virtual environment and find potentially dangerous design issues. An interesting aspect of this technology at USA-Space is that they are looking at coordinated activities of multiple people lifting heavy parts in a very confined space. The movement information of all the participants is tracked and streamed to the digital human software in real-time for analysis. Both the potential injury risk to the technicians and space limitations can be quickly identified.
The use of this VR technology, along with the digital human tool, helps to validate the assembly process of the Orion crew vehicle without building a physical prototype. Even more important, it detects assembly issues before the physical assembly of the crew vehicle itself, which might otherwise cause time delays and increase costs.
To view the full story you could download the video podcast from NASA Edge here. Please be aware that it’s about 620 MB. To see the part of the podcast that shows the usage of Jack you could jump to 16:55 and move on till 23:55. And take a look at the closing which starts at 31:16.

Are Digital Humans Cool?
Thursday, March 19th, 2009
… look at this
Cool, isn’t it?
We used NX in combination with our digital human model called Jack to create this image. Other than the cool factor, these digital humans play a key role in digital manufacturing, both in product engineering and production optimization:
1. In product engineering, they ensure that buyers can use the product. For example, automotive companies use human models to validate the vehicle’s cockpit design to answer questions like, can the seat be adjusted for different drivers so that they can all reach all switches? The same is true for aerospace companies.
2. In production optimization, they validate the ergonomic aspects of assembly situations. For example, can a part be assembled or maintained? Have you ever tried to change the headlamp bulb in your car? If yes, then you know what I am talking about.
Digital human models can also be used to optimize workplaces in regards to process times.
In some cases it might be obvious that a certain task is not appropriate to be done by a worker several times a day, like lifting a heavy tire out of a box. In other cases scientific analysis, like e.g. NIOSH, Burandt-Schultetus or OWAS, can provide a precise result of the ergonomic situation and allow to keep the workers save.
The digital human model can be adjusted to several sizes, shapes and gender … OK, only two genders 
. BTW, Jack’s sister is Jill. If you want to get an impression, see more on this web page.
