50. “It’s just a
big iPod touch!”
- Someone on the Internet

not be well-received

55. “One view onscreen”
no longer the only way

modal content

can be disorienting
on a large display

64. 3. Make it feel real

65. Direct manipulation

67. Tactile, physical
interface design

68. Postage Classics ConvertBot

70. Realistic
sound effects

a mental map
of your app

74. Some specific tips:

Human Interface
Guidelines

76. Work with a
great designer

77. 4x the pixels
=
4x the ugly
