Tromsø Visual Guide. Finding information by snapping a picture with your camera phone, 755kB, PDF

This research note describes the Tromsø Visual Guide (TVG) – a mobile phone based tourist guide based on image recognition, where the user formulates a query to the system by submitting a picture. We describe initial test made with the image recognition software from Evolution Robotics applied to three dimensional objects and the challenges this poses. We describe how the guide is currently functioning, and look at the possibilities of further development of the guide, including ranking and presentation by context and monetization by marketing income from local service providers.

Regulation of mobile termination rates - possible effects of a bill and keep regime, 369kB, PDF

Bill and keep is an interconnect regime where termination rates are determined at zero. In this report we argue that an introduction of bill and keep will result in a tariff rebalancing harming low volume customers and benefiting high volume customers. Furthermore bill and keep is likely to result in more mobile spam and we risk sub optimal routing of telecommunication traffic. Mobile, termination rates, bill and keep, end user prices, regulation.
