Design issues
• Design of widgets
• PIP should fit FOV of the HMD
• Catch events in the „surrounding area“
• Labelling of widgets (esp. buttons, sliders)
Limitations
• „Traditional“ authoring is very time consuming
• Dynamic addition/removal or reconfiguration of widgets/sheets is difficult (hack)
• No standard support of usual 2D widget features such as – Text labels on „mouse-over“– Switching through (sheet)menus with forward
(>), backward (<) buttons
Thank you!
