I think that the capabilities of context-aware sites are a natural evolution of location aware sites (or location based services). Context-aware sites will allow extra dimensions to be added to the personalisation of content, such as time of use, events, weather, temperature & social networks.
A possible scenario for a context-aware site is as follows:
1. You are on your way to a concert and are sitting at a tram stop. You look up the venue’s website. If the site were context aware, it would display travel information on the best way for you to get to the concert, weather information for the concert, and other general information about tonight’s concert.
2. You arrive at the venue, the site would now display you where your seats were located, who of your friends were also at the concert (and where), information about the concert & the list of songs.
3. Finally, after the concert, the site would now show ways for you to get home, other upcoming events you might be interested in, snippets of video from the concert you’ve just been to, and how you can download a copy of the concert.
My view is that with the increase in mobile-based internet usage, including trends such as mobile first, responsive design & geo-location, we will likely see an increase in sites that are context-aware.
With this increase in context awareness, we should see an improvement in the experience of using mobile browsers, which I think will further reinforce the adoption of mobile browsers & usage. I know I’d prefer to use a mobile version of a site that can contextualise and personalise the experience for me – rather than have a desktop version that I’ve got to search or navigate to find the content.
