Photo2search and other opportunities
Note the following project from MSR photo2search.
We ain't seen anything in the context how mobile phones and technology will change our lives.
With more proactive 'agents' in mobiles with appropriate learning and suitable configuration, along with corresponding value propositions very many opportunities are hidden.
First time, I heard about these possibilities (not all of them have led to commercial solutions, as yet) was from papers by Pattie Maes, software agents group between 1996-1998.
It has been about 10 years since she and others have proposed these ideas, now the time is ripe to take them into commercial products.
More than the commercial viability it is the social acceptance that is going to be crucial and challenging.
