Formats like web, CD/DVD, kiosks, interactive TV and mobile apps each have benefits and limitations for delivering information. The web allows accessibility anywhere but requires consideration of different browsers and devices. CDs/DVDs allow portability but not updates. Kiosks do not require internet but cannot link externally or update automatically. Interactive TV needs regular updates but future gestures may be possible. Apps must be visible on small screens and updates sent to users. Each format requires an understanding of its technical capabilities and constraints.

1. FORMATS FOR DELIVERY –
BENEFITS AND LIMITATIONS

2. FORMATS
Web
CD/DVD
Information Kiosks
Interactive TV
Apps for Mobile Devices

3. WEB SITES
Many interactive products can be used via the
internet.
This makes them available wherever people have
internet access. With the increased availability of
Wi-Fi this means virtually anywhere any time.
The developer would have to ensure that the
product would work with a variety of search
engines.

4. Websites allow a user to run videos. Videos and
images can be enlarged for viewing.
Developers need to be aware that not all users have
broadband so need to consider limiting the
amount of data hungry elements such as video.

5. CD AND DVD ROM
Delivering a product via CD or DVD enables a user to
have a portable version.
This could be distributed to users for use at home for
revision or further investigation of a subject at
their leisure.
Once the product has been published updates can’t
easily be delivered, a new version would have to be
published.

6. A CD can only hold approx 750 MB of data whereas
a DVD can hold around 4.7 GB. The product would
have to made to fit on the media that it would be
delivered in.

7. INFORMATION KIOSK
As there would be no internet access the developer
would not be able to include external links that
visited websites that may interest the user.
Any updates would mean re-installing the latest
version of the product and couldn’t be done
automatically.
A lot of features could be included as the system
would not have data download limitations.

8. INFORMATION KIOSK
If the kiosk is going to be in a noisy place then it
wouldn’t be wise to include a lot of sound.
People wouldn’t be spending a long time using it so
it should be very easy to navigate.
The information should be in a straightforward
format that is quick to read and understand.

9. INTERACTIVE TV
The information in an interactive TV situation would
need to be updated on a regular basis.
Gesture recognition will be a possibility in the future.
There is potential for external links to be added if this
feature was required.
Content may be viewed in HD so the any images and
videos will need to be of a very high quality.

10. APPS FOR MOBILE DEVICES
Developers will have to make sure all content is visible on
a fairly small screen to prevent them from having to
scroll around to find information.
Updates can be sent out for users to install at their
convenience.
These products will have to be easy to use and fairly
intuitive they will only have to contain the bare
essential information.
Specific programming languages will need to be used.

11. As you are designing for such a small screen it is
important that everything is kept simple.
Mobile devices have less processing power and
memory so the designer has to take this into
consideration.
