Chapter 2 Design Considerations and Best Practices
Considerations
promotions for family-friendly restaurants at the airport (“kids eat free!”), demonstrations on how to go
thru security, pinpointing the best locations for watching planes take off or land, and cheap
transportation into the city.
Display Logistics
When designing the content, consider the following logistics of your displays:
• The IEC4600 Series can support a video display that is up to 1920x1080 (1080p). The IEC4600
Series defaults to the monitor’s native resolution.
• To ensure the content scales well, build for the lowest resolution expected. Then use stretchers to
make sure it can stretch to the highest resolution expected.
• Both horizontal (landscape) and vertical (portrait) modes are supported with 90, 180, 270 degree
turns.
• The content should be laid out naturally.
• Kiosk placement should be planned to optimize viewing distance from foot traffic.
• Determine how far away users will be from the screen when it is first seen. If users will first see the
screens at close range, the layout can be divided into more zones than if users will be seeing the
screens from far away.
• Preview your designs on a touch screen that is the same size as the ones that will be installed.
Bandwidth Considerations
The most compelling content can have little impact if it never reaches the user. This can happen if there
is limited bandwidth to the kiosk. Find out the bandwidth capabilities of the kiosk locations and build
content with the limitations in mind. If different locations have different bandwidths, create different
playlists. In locations with limited bandwidth consider using more static graphic, reducing the size of
videos, and cutting up a video and distributing the segments throughout the playlist.
Caching
Web caching is limited to HTTP1.1 caching specification meaning that the client has to consult the server
for caching instructions, file timestamps, time-to-live, etc.
Video caching is handled by a separate caching mechanism (assuming the videos are played via native
player widget), which has a rich browser API.
Refreshes
How often you refresh content is dependent on a variety of factors:
• Frequency of visits: How often does your audience return to the area where the kiosk is located -
once a day. once a week, once a month?
• Audience expectations: Will your audience expect to see new content every time they visit your
store, branch, station, or terminal?
