4. The Effect of Audio-Visual Smiles on Social Influence in a Cooperative Human-Agent Interaction Task

Author

Torre, Ilaria, Carrigan, Emma, Domijan, Katarina, McDonnell, Rachel, Harte, Naomi, Torre, Ilaria, Carrigan, Emma, Domijan, Katarina, McDonnell, Rachel, and Harte, Naomi

Abstract

Emotional expressivity is essential for human interactions, informing both perception and decision-making. Here, we examine whether creating an audio-visual emotional channel mismatch influences decision-making in a cooperative task with a virtual character. We created a virtual character that was either congruent in its emotional expression (smiling in the face and voice) or incongruent (smiling in only one channel). People (N = 98) evaluated the character in terms of valence and arousal in an online study; then, visitors in a museum played the "lunar survival task" with the character over three experiments (N = 597, 78, 101, respectively). Exploratory results suggest that multi-modal expressions are perceived, and reacted upon, differently than unimodal expressions, supporting previous theories of audio-visual integration., QC 20220112

5. Dimensional perception of a ‘smiling McGurkeffect’

Author

Abstract

Multisensory integration influences emotional perception, as the McGurk effect demonstrates for the communication between humans. Human physiology implicitly links the production of visual features with other modes like the audio channel: Face muscles responsible for a smiling face also stretch the vocal cords that results in a characteristic smiling voice. For artificial agents capable of multimodal expression, this linkage is modeled explicitly. In our study, we observe the influence of visual and audio channel on the perception of the agent’s emotional state. We created two virtual characters to control for anthropomorphic appearance. We record videos of these agents either with matching or mismatching emotional expression in the audio and visual channel. In an online study we measured the agent’s perceived valence and arousal. Our results show that a matched smiling voice and smiling face increase both dimensions of the Circumplex model of emotions: ratings of valence and arousal grow. When the channels present conflicting information, any type of smiling results in higher arousal rating, but only the visual channel increases the perceived valence. When engineers are constrained in their design choices, we suggest they should give precedence to convey the artificial agent’s emotional state through the visual channel., Part of Proceedings: ISBN 978-1-6654-0019-0QC 20211026

Abstract

International audience; Our work is a perceptual study into the effects of training poses on the Example-Based Facial Rigging (EBFR) method. We analyse the output of EBFR given a set of training poses to see how well the results reproduced our ground truth actor scans compared to a Deformation Transfer approach. While EBFR produced better results overall, there were cases that did not see any improvement. While some of these results may be explained by lack of sufficient training poses for the area of the face in question, we found that certain lip poses were not improved by training, despite a large number of mouth training poses supplied.

Abstract

The article discusses the harvesting experiences of cotton growers in March 2007 in various districts in Australia. In Central Highlands, a grower shares that majority of the crops in the area were harvested in two to three weeks. In Dawson Callide, a grower reports that the valley have grown 3,200 hectares of cotton for the 2006-2007 season. In Darling Downs, a grower comments that the temperature durng the last growing season was very favorable.

14. The challenge of a new lateral move or centre pivot.

Author

Carrigan, Emma, Harris, Graham, and Hood, Sarah

Abstract

The article presents three case studies which highlighted problems with center pivot and lateral move overhead irrigation machines in Australia. In the first case, several issues were discovered in such machines, including the incorrect placement of the pressure regulators at the top of the dropper instead directly above the sprinkler. It was also found that the center pivot machine had lost end pressure that resulted to more water releases at its head ditch whenever the machine reaches the highest point of a field.

16. Siphon-less irrigation systems: So how did they perform?

Author

Hood, Sarah and Carrigan, Emma

Abstract

The article provides information on several siphon-less irrigation systems commonly employed in the cotton industry in Australia. The definitions of water use efficiency indices are cited. Increased waterlogging and a decline in water for irrigation are among the possible results of a compaction in a bank-less irrigation system.

Author

Carrigan, Emma

Abstract

The article reports on the status of the cotton industry in Macintyre Valley, New South Wales. The cotton planted has been divided between Bollgard and conventional varieties. It is said that the dry season has benefited crops by developing a strong ad healthy root system. Most growers plan and implement limited water irrigation strategies due to warm conditions.

Author

Carrigan, Emma

Abstract

This article provides information on the 2004-05 cotton season in Macintyre Valley and Mungindi, New South Wales. The 2004-05 season provided some outstanding results, with farm averages ranging from 9.4 bales per hectare in a water limited situation up to 11.4 bales per hectare under full irrigation. The average across the Border Rivers is estimated to be 10.4 bales per hectare. The season started with The Irrigation Association of Australia field day held in Goondiwindi, which showcased the latest technology available to irrigators to improve their irrigation practice and maximize the return per megaliter. The Border Rivers is currently prepared for approximately 50 percent of the production area to go into cotton for the 2005-2006 season.

19. The focus turns to water.

Author

Carrigan, Emma

Abstract

The article offers observation on the continuous monitoring of water storage levels at Milo cotton farm in Australia. According to Tony Bailey, who manages the irrigated cotton at Milo, water is the most valuable resource for them. And with the increasing pressure on water security, they need to measure the resource to enable them to better manage it. In doing so, they can ensure the longevity of a sustainable irrigated cotton production system. The drought, although devastating for most, offered the farm an opportunity to start the process of measuring their water stored on-farm. The team set about Beelining, the dry water storages, using their own equipment to determine the volume of the dams. The volume of the water stores in the dams is calibrated to an Odyssey pressure sensor which enables the storage depth, in-flows and out-flows to be continuously monitored. Knowing how much water the producers have in on-farm storages empowers the grower and creates opportunities to fine its use. The monitoring of levels in storages adds another dimension to the management of water on-farm at Milo. Improved water budgets with accurate water balances enables Milo to fine tune their area of production, the amount of tail-water recovered and the amount of water applied in-field.
