Using Images & Multimedia in online surveys 2

Continuing our tips on the better use of hotspots, audio and video

6. Using multiple images as answer options

Demographix allows you to upload a series of images individually to be included as answer options in a question. For example, you could upload a group of brand logos and include them in a single choice question ("Click on the brand you like the most from this list") or in a multi-choice question ("Click on the three brands you like best from this list"). The key thing to watch out for here is to give the brands equal visual weight and space — for example, by making all your image files the same dimensions. Better still, use Hotspots to combine image options (see 7).

7. How to combine all your answers in one hotspot image

Our newly-introduced image hotspots allow you to create streamlined questions with much less work involved than manipulating individual images. For example, create an image with 4 images in it, and use the hotspot grid creation tool to specify the areas taken up by these hotspots. Then use the hotspot question type to create a range of questions based on the image: single-choice, multi-choice, ranking, and note attachments can all be applied to hotspot images. In the image above, there are 4 different hotspot questions based on the same grid.

8. Using audio files in online surveys

Adding an audio file to a survey has never been easier. We've also done a lot of work recently to make audio files compatible with any environment in which a survey may be viewed (from desktop Macs and PCs to Android smartphones, tablets, iPhones and iPads). Different operating systems and browsers support different audio formats (though primarily MP3 and OGG) and Demographix surveys automatically use the version of the file needed. But we do the conversion for you — simply upload your audio file in one of the formats we support (MP3, OGG, WAV or AAC), wait for email confirmation, and then add it to your survey. We'll do all the behind-the-scenes work on the file.

9. Using video files in online surveys

As with audio files (8 above), Demographix users can upload a video in a wide range of formats — FLV, MP4, WMV, MOV, AVI, MPG, MPEG, OGV, OGG, WEBM or M4V. We convert the file into the formats needed for different devices and browsers. Flash files, for instance, are not supported on Apple devices; so we substitute a version automatically that is compatible. Once uploaded through the Media toolset, you'll receive email notification that it has been converted into all formats. Then, simply add the video to your survey, using the multimedia option under question types, and insert relevant questions beneath it.

10. Be careful with video format sizes

There are optimal widths and aspect ratios for all videos, so take care before you upload your video to check out that it is not too large for the width of your survey. There are tools available on the interent for resizing your videos, while preserving aspect ratio. Subscribers are asked to contact the Helpdesk when logged into Demographix, if they need further advice on video resizing and conversion.
