Can devices improve medication adherence?

Link to the article in the Wall Street Journal.

My reaction:

Blister packing works well and is relatively easy for brand name manufacturers to incorporate.  I could see this as a possible competitive advantage.  Generic manufacturers have little incentive to add this cost.

If you want something to remind you then an alarm on the cellphone seems to have the most utility.  You could also set up a service that uses text messaging to remind and confirm.  Physical devices don't make sense to me.
