The majority of digital games available today offer a variety of multi-player settings including co-located and mediated play between opponents. Immersion, the sense of being " in the game, " is one of the key components of the gaming experience but existing literature suggests that social play provides more fun but less immersion. There is however little… (More)
In this paper, we describe a simple system to recognize emotions from short video sequences, developed for the Emotion Recognition in the Wild Challenge (EmotiW 2013). Performance matches the challenge baseline whilst being significantly faster and lower in complexity. Our experiments and subsequent discussion provide a number of insights into the problem.
The effectiveness of the cascaded object detector has been demonstrated repeatedly, and the basic steps to generate one are well known. But it is not obvious how to ensure the resulting detector will be efficient. This paper offers a solution by introducing a performance criterion that combines detection rate, false positive rate and speed, and a new cost… (More)
In this paper, we describe an entry to the third Emotion Recognition in the Wild Challenge, EmotiW2015. We detail the associated experiments and show that, through more accurately locating the facial landmarks, and considering only the distances between them, we can achieve a surprising level of performance. The resulting system is not only more accurate… (More)
We explore the open problem of the most efficient way to communicate classical data across quantum channels. We find that traditional optimal measurement techniques do not necessarily maximise information transfer rates and therefore the maximisation of the mutual information must be done explicitly. This inherently non-linear problem has been solved for… (More)
Since The Meaning of Evolution (1992), Robert J. Richards has argued that modern evolutionary theory is rooted in late 18th-century Romantic science. The publication of The Tragic Sense of Life (2009) provides a fitting occasion to evaluate how this perspective revises the standard history of biological thought. This essay focuses on three aspects of… (More)
