The following interaction user story describes different actions the user can take to navigate through the oculus rift environment of the project Datasphere. For a description of the project at hand please refer to
the basic info section.
The oculus rift device works as a mouse pointer would on a desktop monitor. The way the user turns their head dictates where your pointer is on the screen. The name we have given for the users fixed point of view is the gaze. In order to select an item the user must gaze on the widget or text they would like to manipulate.
As a user keeping a prolonged gaze with allow a selection of the widget. To indicate this motion has worked the widget will then in turn have a green halo which indicates the user is able to interact with that particular item.
The gaze feature works when selecting text. Once the text has been selected the user can navigate through their choices using the gaze motion.
The user needs to have the ability to see all of the widgets at any point in time. To see the widgets to the left or right of the focus the user can use an open hand swiping motion to sweep through the widgets from left to right.
The data within the widget cards can only be filtered or magnified if the card is in the foreground referred to as the rail space. The row of widgets in the dark blue space, aka the shelf space becomes the background if a widget is selected. To pull a widget off the shelf the user can use a pinching motion in the corner of the selected widget. Once the item is in "hand" the user can pull it towards them to place the widget on the rail. Once this action has been completed the data within the widget can now be filtered and manipulated.
The user may need to be able to see closer within certain widgets, such as a map. To magnify the content within the widget the users must hold up two flats palms facing toward the card and use horizontal sliding motions to expand and contract the data inside the widget. All the while, the outside perimeters of the card remain fixed.
To filter the value of data within a widget already in the rail space the user must use a gaze motion to select particular data sets.
In order to move the location of the map contents inside of the card, the user must use a closed fist with pointer finger out to select a spot on the image and then proceed to move the finger in any directions to navigate around the space.
If all desired actions have been completed with a card in the rail space the user can return the card to the shelf with an open palm pushing the haloed item to the background - or back on the shelf. The focus is once again on the items in the shelf and only those widgets can be manipulated again.
