This document summarizes research into developing a new TV program discovery application called TV Discovery & Enjoy (TvDE). TvDE aims to help users more easily find TV programs to watch by considering their preferences and context. It integrates live, recorded, and on-demand content sources. An evaluation involved users testing a prototype. They found the interface easy to use and recommendations generally suitable. Most saw value in TvDE for the home, especially heavier TV viewers. The research concludes TvDE shows potential as an alternative to electronic program guides by better mapping users' cognitive selection processes.

criteria vs the preliminary survey results
> evaluate the application usability
> determine the suitability of the recommendations to
the chosen criteria
> evaluate the user experience and the expectations
towards the use of the application.

Bachelor (40%)
Masters (25%)
PhD (30%)
Students (50%)
Working-students (20%)
29. The evaluators
High percentage of timeshifted TV consumption
Using other media devices apart from regular TV
Low frequency of use of the TV providers services (DVR,
Vod,…)
2 groups of 10 users each:
LC lower TV consumption
HC higher TV consumption

HC 70% much interested

An application which maps the cognitive processes of users
has a very interesting potential, especially as an alternative
to the traditional model of EPGs (grid based).

Editor's Notes
digitalsmiths
To establish a ranking of the most relevant criteria a non-parametric statistical test was performed using a Durbin and Skillings-Mack test (Table 2). The test corroborates that there is a significant difference between the presented criteria confirming, with a confidence level higher than 99,99%, that viewers prioritize some features of the content or of the viewing context over others when having to decide what to watch. The test confirms that the “program genre” leads the preferences of viewers, the “state of mind” or mood follows and “being alone or accompanied” and the “available time” split the 3rd place. The other criteria are less relevant for spectators.
Doing a cross analysis of these data with the gender of the respondents, we can conclude that the order of the criteria is the same for both genders. Nevertheless we can notice that man have slightly higher preference for the “program genre” and women for the “state of mind”. Considering the age groups, we can conclude that for the younger group and the older one the available time is more important than the fact of being alone or accompanied.
With some additional correlations it can be seen that viewers who watch among friends pick the state of mind or mood as the main criterion. Additionally when considering the average time viewers take to select the program it can be seen that those who take more than 10 minutes to choose what to see point to “Being alone or accompanied “ as the most important criterion.

36% of the sample point to a mid-level in a scale from “I never know” to “I always know”. Women more often declare they know in advance what they want to see. When asked about the time taken, on average, to choose what program to watch, more than half (51%) say they take between “1-3 minutes” and about 31% "less than 1 minute." In these situations, men appear to be faster. Also ZON customers emerge as the fastest finding what they want to see on TV.

navigation between recommended programs and the definition of the criteria were the features that had better appreciation by the users of both group
