“HUD(Head Up Display) 기술의 활용처는 무한합니다. 내비게이션으로 우선 개발했지만 군사와 의료 용도로도 효용성이 뛰어납니다. 원천기술을 확보해 세계무대에서도 충분한 경쟁력이 있습니다.”
건설기술연구원 강원의 연구위원은 “HUD는 미래 내비 시장의 새로운 동력이 될 것”이라고 자신했다.
건설기술연구원 첨단교통연구실이 HUD 국산화에 성공했다. HUD는 차량에 주행 정보를 표시해 주는 디스플레이 기술. 차량 앞면에 각종 주행 정보를 쏴줘 내비게이션으로 활용하는 식이다. 전방과 내비를 번갈아보면서 발생하는 운전자의 혼란을 개선한 차세대 디스플레이다. BMW·벤츠 등 극히 일부 자동차 업체만 해당 기술을 갖고 있을 정도로 진입 장벽도 높았다. 연구원은 국책 과제로 4년 만에 이를 따라잡았다. 그것도 기존 기술에 비해 성능 면에서 훨씬 앞섰다.
“HUD의 생명은 선명도입니다. 즉 밝기입니다. 흐릿한 영상은 오히려 운전자에게 혼란을 주기 때문입니다. 이번에 개발한 기술은 외국에 비해 훨씬 선명한 영상을 구현합니다. 게다가 구현 방법도 개선했습니다. 자동차 앞 유리는 보통 두 장의 유리를 겹쳐서 제조해 정보를 투사하면 화면이 겹치는 ‘고스트 영상’이 발생했습니다. 이 때문에 이전 업체는 편광필름을 넣는 방식으로 HUD를 구현했습니다. 그러나 연구원은 별도 필름 작업 없이 영상을 보다 선명하게 보여 줍니다.”
물론 쉬운 작업이 아니었다. 처음에는 단순하게 판단했는데 개발 과정이 만만치 않았다. 시행착오의 연속이었다. 투자 재원도 12억원에 불과했다. 기술력·예산·인력 어느 것 하나 충분한 게 없었다. 이 때문에 국산 HUD 장비를 공개했을 때 이미 수백억원을 투자했던 자동차 업체들이 혀를 내둘렀다는 후문이다.
“처음에는 막막했습니다. 무작정 HUD를 장착한 BMW를 구입해 뜯어봤습니다. 특허를 피하기 위해서는 같은 방식은 힘들었습니다. 그럭저럭 영상 표출에 성공했는데 이중상이 발생하고 깊이감이 부족했습니다. 2차 연도에 이를 개선했는데 이번에는 발열이 문제였습니다. LED를 광원으로 사용해 상대적으로 열 문제가 심각했고 시스템이 불안정해지는 현상이 빚어졌습니다. 냉각기술 등으로 이를 보완했는데 색상과 도안, 차량과 내비 정보 연계 등 운전자 입장에서 친화성이 떨어지는 현상이 빚어졌습니다.”
연구원은 결국 4년 만에 외부에 공개할 만한 기술력을 확보했다. 가장 중요한 밝기는 30만 칸델라급으로 시제품을 내놨지만 120만칸델라까지 구현했다. 색상도 기존 기술은 두 가지인데 비해 6가지로 선보였다. 강 연구위원은 좀 더 과감한 투자가 이뤄졌다면 훨씬 더 뛰어난 제품을 앞당겨 내놓을 수 있었을 것이라며 아쉬워했다.
“HUD 시스템 핵심 기술의 하나는 광학입니다. 쉽게 말해 렌즈를 좀 더 얇게 깎는 기술입니다. 이게 모두 돈입니다. 그러나 상용화를 위해서는 반드시 필요한 과정입니다. 앞으로 이를 보완해 나갈 계획입니다.” 연구원은 원천기술을 확보한 이상 차량용 내비에 그치지 않고 군사·의료용도로 활용 범위를 넓혀 나갈 계획이다. 기술 이전으로 시장을 키우고 다른 분야와 접목해 응용 분야를 개척하기로 했다.
강 위원은 “활용 분야는 무궁무진하다”며 “미래 디스플레이 기술로 비전이 밝다”고 강조했다.

Synchronize SharePoint content with SharePoint Workspace

Applies to: Microsoft SharePoint Foundation 2010 , SharePoint Server 2010

Using Microsoft SharePoint Workspace 2010, you can work with SharePoint 2010 sites, libraries, and lists on your desktop computer or laptop, whether in or out of the office. Synchronization of changes between your computer and the SharePoint server are handled in a smooth and efficient manner. Using SharePoint Workspace 2010 can help save you time and help manage your collaboration efforts much more effectively.

Introduction to synchronizing SharePoint 2010 content with SharePoint Workspace 2010

Using Microsoft SharePoint Workspace 2010, you can work with SharePoint 2010 sites, libraries, and lists on your desktop computer or laptop, whether in or out of the office. Synchronization of changes between your computer and the SharePoint server are handled in a smooth and efficient manner. Using SharePoint Workspace 2010 can help save you time and help manage your collaboration efforts much more effectively.

When you are connected, synchronization can occur automatically behind the scenes, although you can make the changes manual if you want. When you are not connected —at home, on the road, or in the air — you can continue to work on your computer. When you come back online, SharePoint Workspace 2010 synchronizes changes you and others made while you were offline.

For example, you can edit documents, presentations, files, and lists (both native and external) on your computer while offline on a business flight. You can do this by using your standard Office products and features, such as Office Word 2010, Office Excel 2010, and Office InfoPath 2010. When you come back online to your SharePoint 2010 sites, all the changes can be synchronized automatically, and any conflicts resolved smoothly.

To synchronize a SharePoint site, library, or list, you must have SharePoint Workspace 2010 installed on your client computer and you must have Contribute permission to the site, library, or list.

Find more information about using SharePoint 2010 with SharePoint Workspace 2010 in the See Also section and in the SharePoint Workspace 2010 Help system.

What is Synchronization?

In short, synchronization means that any changes made on your computer or the SharePoint server are continually reconciled so that the content is the same on both computers. This synchronization is two-way or bi-directional. Changes made on your computer are uploaded to the server, and changes made on the server are downloaded to your computer. SharePoint Workspace 2010 synchronization is also efficient; only the changes to a file or list are synchronized, not the entire file or list.

Working with documents in SharePoint libraries

You can work with files in SharePoint libraries on your computer by using SharePoint Workspace 2010. The library view in SharePoint Workspace 2010 is very similar to the view in SharePoint 2010. Custom columns, views, and content types are supported. This includes library views, both public and private.

Custom properties, such as title, priority, and keyword, show up in Word, Excel, and PowerPoint Document Information Panels. Even the New command with any defined content types works in a similar manner.

You can also open and save Office files, such as documents, spreadsheets, and presentations, from and to your local workspaces by using the familiar Office Open and Save dialog boxes. You can even drag and drop files from Windows Explorer to your SharePoint workspace.

Checking in, checking out, and creating major and minor versions is also supported. Related commands are enabled on the SharePoint Workspace ribbon when you are online, but unavailable when you are working offline.

Note that an Office file, such as a Word document or PowerPoint presentation, is treated by SharePoint Workspace 2010 the same way that it would treat a file opened directly from the browser, and even maintains the URL, which you can view and copy in Backstage view.

Working with list data

You can work with SharePoint lists, both native and external, on your computer by using SharePoint Workspace 2010. Most types of columns, metadata, and content types are also supported in SharePoint Workspace 2010. This includes list views, both public and private.

If an occasional conflict occurs when two or more people edit the same list item, then you can use the conflict resolution dialog box to resolve the conflict and be on your way. Even when list metadata changes on the server, the new list metadata can be synchronized on your computer. For example if a calculated column is added on SharePoint 2010, then SharePoint Workspace 2010 picks up the change the next time synchronization occurs.

External lists, created by using Business Connectivity Services (BCS) in SharePoint Designer 2010 are also supported. External lists can contain read/write access to Line-of-Business data from data sources, such as SQL Server or SAP. This means that you can work with your external list data from within SharePoint Workspace 2010, whether online or offline, and smoothly synchronize your changes directly to the external data source.

You’ll find it easier and faster to add and edit list item data and metadata on your computer in a SharePoint Workspace 2010 than in a browser on a SharePoint site. You can view the list data in a grid-like view, and edit the data in a form. The split form feature gives you a unique and practical view into your data.

If an InfoPath form designer has associated an InfoPath 2010 form with the list, you can synchronize that form and use it in your SharePoint Workspace 2010. This means you can take advantage of InfoPath’s form features such as spell checking, file attachments, rich text, field validation, and business rules.

Searching SharePoint Workspace 2010 content

Searching SharePoint Workspace 2010 content works in a smart and robust way:

  • When you search in a workspace or from the Launchbar, you can find content across all your site workspaces.
  • When you search from the Microsoft Windows 7 Start button, you search across your desktop and all your downloaded content from SharePoint Workspace 2010. Workspaces are automatically indexed. Local search is fast and works whether you are offline or online.

Synchronize a SharePoint workspace with a SharePoint site

  1. In your browser, navigate to the SharePoint site you want to synchronize.
  2. Click the Site Actions menu, and then click Sync to SharePoint Workspace.
  3. To selectively control which libraries and lists are downloaded:
  1. Click Configure.
  2. For each list or library, select it, and then in the Download box, select Headers Only (libraries only) or No Content. You can download the full content later on if you need to.

The first time you synchronize an entire site, it may take a few minutes to download all the files on your computer, but this occurs behind the scenes, so you can continue to work on other tasks.

 Note    If the site contains subsites, these are not downloaded, but you could download those separately if you need to.

Synchronize a SharePoint workspace with a specific library or list

You can select a specific library or list, if that's all you need to work with from a site. You might want to be selective about what you download to save space on your personal computer or because you do not have permission to synchronize the rest of the site.

  1. In your browser, navigate to the SharePoint site containing the list or library you want to synchronize.
  2. Click the name of the list or library on the Quick Launch, or click Site Actions, click View All Site Content, and then in the appropriate list or library section, click the name of the list or library.

 Note    A SharePoint site can be significantly modified in appearance and navigation. If you cannot locate an option, such as a command, button, or link, contact your administrator.

  1. In the ribbon, on the List or Library tab, in the Connect & Export group, click Sync to SharePoint Workspace.
