UBIK HoloLens 2 Client Basics
Contents
Login
The Hololens 2 Client's login menu offers a selective list of all locally stored profiles. On start up the last used profile is selected by default. After selecting the desired profile, pressing the login button starts the login process and disables the buttons of the login menu for the duration of the process. To interact with the login menu the finger pointer is used.
System Menu
When logged in the user can use the system menu to access general features. The System menu is acessed by looking at the palm of your hand and consists of a grid of buttons.
POIs
Creation and Deletion
POIs are the HoloLens representations of UBIK content objects. They can be placed using the Create POI button in the System Menu. This opens the search menu, which allows the input of a search term using the Hololens 2 virtual keyboard. After the input is finished the search starts. When finished the result list below the search input is populated with results. Each result is a button which spawns the corresponding POI and closes the search menu. Upon creation the placement of the POI automatically starts. Using the Hand Ray allows you to aim the POI and Finger Tapping places it at that position. To delete a POI select it and in the System Menu press the Delete POI button, or press the Clear POIs button to delete all POIs. The position of POIs is persisted locally between sessions.
Levels of Detail
A POI can display more or less information based on the distance to the POI and it's selection status. Level 1 shows only the POI's position and its status color. Level 2 additionally shows the name, a short description, and the Icon. Level 3 additionally shows the high priority properties and if available the child count as well as the document count.
Manipulation
POIs can be moved at a distance by aiming the Hand Ray at the POI and holding the Finger Tap, or up close by directly moving the hand into the POI and holding the Finger Tap.
Context Menu
The context menu gives access to POI specific actions as well as detailed data about the POI object such as a full list of properties documents and children connected to the POI object.
Documents
Documents behave similar to POIs in the way they are placed and moved. To start placing a document press the corresponding button in the document list inside the context menu of a POI object. The placed document is displayed in a scalable window which also include a close button to delete the POI. Specific kinds of documents like videos and PDFs contain specific controls like play and pause for videos.
Quest Log
The Quest Log is a panel that can hold a list of tasks and work packages for the user. It can be opened from the system menu and is located centrally below the users natural field of view. By pressing the work package items in the list users can navigate into the work package and see its content. By default the Quest Log follows the user and stays in its dedicated position, but it can also be placed by the user manually.
