Q

Problems with direct manipulation

A

Uses screen space
Bad for disabled users
Recording local inverses of actions or undo is a lot of work to implement
Making underlying databases work fast enough is hard

25
3D design guidelines
Minimize necessary steps Keep text readable Minimize visual clutter Keep movement planar, euclidian, and phsically possible Simplify object movement
26
3D software design
Include optional telleportation, X-Ray, history, and saving of individual objects
27
Examples of physical precense
Millitary, remote surgery, chemical plant operation, manufacturing robot control.
28
Why robotic surgery
Damps out certain involuntary movements
29
Problems with telleprecense
Time delays Incomplete feedback Unanticipated interference
30
AR
Chemical and medical applications are the only non-dystopic ones
31
VR
Auctually usefull to treat PTSD, some gaming, some fashion, probably not design
