Glisser makes presentations social. It incorporates live presentation slide sharing to audience devices, audience response systems, live polling, Twitter feeds and other audience interaction. It can be used by both individual presenters and speakers, as well as event organisers, to make presentations more engaging and collect valuable data. The Glisser platform takes regular PowerPoint or Keynote slide decks and pushes them out live to audience mobile devices, slide-by-slide, as they are presented. It then enables members of the audience to interact with the presenter or each other, and collects their feedback. Attendees can also electronically mark-up the slides with notes, and keep them for future reference. Glisser integrates slide-by-slide ‘like’ voting, live audience questions, Twitter (plus ‘Tweet-a-Slide’), as well as polling and feedback slides integrated seamlessly within the original deck. There is no need for a second monitor or technical support to switch screen feeds, as Glisser can be operated by a lone presenter from a single device. It’s that simple. Audience members can access slides via their web browser – a solution that works across all major devices including Windows Phone and BlackBerry, without any download required. Presenters can set up presentations in a few minutes, simply by uploading their files (PPT, PPTX, PDF) at the glisser.com website, switching on the social features they want to include, and dragging-and-dropping in audience polls. They then get a unique code to send to their audiences, to use in-app or via their web browser.
