digital ACT measures for left and right eye fixing respectively were on average 2.9Δ (95% limit of agreement [LOA]: ±4.6) and 3.0Δ (95% LOA: ±6.1) more eso than the clinical PACT, which may be due to stimuli differences. Measurements were consistent between the two repeats of the digital ACT, with mean differences of -0.4Δ (95% LOA: ± 4.6) and -0.2Δ (95% LOA: ± 5.5) for left and right eye fixing. Conclusions: Low-cost eye trackers and 3D displays can be used to quickly assess ocular deviations at multiple gaze directions. Results strongly correlated with standard clinical PACT. This type of test may be useful in clinical settings, such as for repeated measurements or for children.

Rose, D. & Bex, P.J. (2018) Semantic Scene Statistics Using a Novel Computational Method. Presented at the European Conference on Visual Perception.
Correlations between semantic and image saliency maps, averaged across images in this subset, were modest but highly significant for both semantic saliency map types. The average correlation coefficient for image to object-object saliency maps was 0.35 (one-sample t-test, t=26.5,df =209, p<0.0001); for image to object-scene it was 0.33 (t=25.9, df =209,p<0.0001). ROC analyses of gaze position alignment with salience maps of both types indicate that object-object or object-semantic saliency were significantly better predictors of gaze than image salience across tasks (Tukey HSD post-hoc test, p<0.0001 for both image/object-object and image/object-scene), with equivalent performance between the semantic saliency map types (p=0.68).
Taken together, we believe these results support the use of our method for calculating semantic saliency, alone or in combination with other top-down and bottom up salience models, for predicting gaze. Object-scene semantic saliency in particular represents a novel method for including potentially important information regarding the role of novel or contextually unlikely scene content on gaze guidance.

mouth and forehead, at random across trials) in a 2AFC task. The name or feature of the test face was paired with a name or same feature from a different face. Binocular gaze direction was tracked using a 60Hz eye tracker. Face identification was significantly worse for line drawings than upright faces (p< .0001). Gaze direction varied as a function of face feature (p< 0.001) with more fixations towards the eyes and nose than any other features (all p< 0.05), and more fixations to left than right eye (all p< 0.05). Participants made fewer fixations on the eyes of all non-upright faces or selfies compared to upright faces (all p< 0.05), but fixation patterns were not significantly different for face naming than feature recognition (p<0.87). In agreement with previous research, gaze direction is not uniformly distributed across faces. However, changes in image type can modify the pattern of eye movements at no expense to identification accuracy. Furthermore, changes in task type failed to modify fixation patterns. These findings are not consistent with a single information-driven goal of eye movements

Accurate detection of vision change is important in diagnosing and monitoring visual disease progression and treatment effects. In this study, we evaluated the accuracy of three tests in detecting vision changes: the e-ETDRS (Beck et al., 2003), a new Bayesian visual acuity test (Lesmes, 2017), and qCSF assessment of the contrast sensitivity function (Lesmes, et al, 2010; Hou, et al, 2015).Methods
Monocular visual acuities and contrast sensitivities were measured with the three tests in both eyes of six subjects with normal or corrected-to-normal vision in four simulated vision conditions (no foil and three different levels of Bangerter foil that degraded vision). Each session tested one foil condition. Subjects were tested monocularly with both the new Bayesian visual acuity and e-ETDRS methods 4 times, with random test order of the two methods and two eyes in different blocks. At the end of each session, the contrast sensitivity function of each eye was measured with the qCSF method. An ROC analysis (Hou et al., 2016) was conducted to evaluate the accuracy of the methods in detecting changes in visual acuity and area under the log CSF (AULCSF) associated with different foil conditions. The analysis consisted of computing (1) the average acuity from repeated e-ETDRS measures in each eye and foil condition for each subject; (2) posterior distributions of the estimated VA from the new visual acuity and e-ETDRS tests and AULCSF from the qCSF, (3) the accuracy of detecting acuity changes (averaged across all 16 possible combinations of the four repeats in each condition) and AULCSF changes between each pair of foil conditions; (4) the average accuracy in three ranges of mean acuity changes: 0.02-0.05, 0.05-0.10, and 0.10-0.20 logMAR.Results
For detection of visual function change, the qCSF with 50 trials had the highest accuracy (0.996 ± 0.008, 0.996 ± 0.007, and 0.987 ± 0.020 in the three ranges), followed by the new Bayesian visual acuity test with 45 trials or 135 letters (0.874 ± 0.038, 0.910 ± 0.047, and 0.971 ± 0.036), and lastly by the e-ETDRS test with 30.8 ± 5.4 letters (0.826 ± 0.036, 0.808 ± 0.029, and 0.0.905 ± 0.042). Conclusions Bangerter foils produce deficits in visual function beyond visual acuity. The qCSF was the most accurate test for these deficits, and the new Bayesian VA test is more accurate than e-ETDRS in detecting associated visual acuity changes.

digital ACT measures for left and right eye fixing respectively were on average 2.9Δ (95% limit of agreement [LOA]: ±4.6) and 3.0Δ (95% LOA: ±6.1) more eso than the clinical PACT, which may be due to stimuli differences. Measurements were consistent between the two repeats of the digital ACT, with mean differences of -0.4Δ (95% LOA: ± 4.6) and -0.2Δ (95% LOA: ± 5.5) for left and right eye fixing. Conclusions: Low-cost eye trackers and 3D displays can be used to quickly assess ocular deviations at multiple gaze directions. Results strongly correlated with standard clinical PACT. This type of test may be useful in clinical settings, such as for repeated measurements or for children.

Rose, D. & Bex, P.J. (2018) Semantic Scene Statistics Using a Novel Computational Method. Presented at the European Conference on Visual Perception.
Correlations between semantic and image saliency maps, averaged across images in this subset, were modest but highly significant for both semantic saliency map types. The average correlation coefficient for image to object-object saliency maps was 0.35 (one-sample t-test, t=26.5,df =209, p<0.0001); for image to object-scene it was 0.33 (t=25.9, df =209,p<0.0001). ROC analyses of gaze position alignment with salience maps of both types indicate that object-object or object-semantic saliency were significantly better predictors of gaze than image salience across tasks (Tukey HSD post-hoc test, p<0.0001 for both image/object-object and image/object-scene), with equivalent performance between the semantic saliency map types (p=0.68).
Taken together, we believe these results support the use of our method for calculating semantic saliency, alone or in combination with other top-down and bottom up salience models, for predicting gaze. Object-scene semantic saliency in particular represents a novel method for including potentially important information regarding the role of novel or contextually unlikely scene content on gaze guidance.

mouth and forehead, at random across trials) in a 2AFC task. The name or feature of the test face was paired with a name or same feature from a different face. Binocular gaze direction was tracked using a 60Hz eye tracker. Face identification was significantly worse for line drawings than upright faces (p< .0001). Gaze direction varied as a function of face feature (p< 0.001) with more fixations towards the eyes and nose than any other features (all p< 0.05), and more fixations to left than right eye (all p< 0.05). Participants made fewer fixations on the eyes of all non-upright faces or selfies compared to upright faces (all p< 0.05), but fixation patterns were not significantly different for face naming than feature recognition (p<0.87). In agreement with previous research, gaze direction is not uniformly distributed across faces. However, changes in image type can modify the pattern of eye movements at no expense to identification accuracy. Furthermore, changes in task type failed to modify fixation patterns. These findings are not consistent with a single information-driven goal of eye movements

Accurate detection of vision change is important in diagnosing and monitoring visual disease progression and treatment effects. In this study, we evaluated the accuracy of three tests in detecting vision changes: the e-ETDRS (Beck et al., 2003), a new Bayesian visual acuity test (Lesmes, 2017), and qCSF assessment of the contrast sensitivity function (Lesmes, et al, 2010; Hou, et al, 2015).Methods
Monocular visual acuities and contrast sensitivities were measured with the three tests in both eyes of six subjects with normal or corrected-to-normal vision in four simulated vision conditions (no foil and three different levels of Bangerter foil that degraded vision). Each session tested one foil condition. Subjects were tested monocularly with both the new Bayesian visual acuity and e-ETDRS methods 4 times, with random test order of the two methods and two eyes in different blocks. At the end of each session, the contrast sensitivity function of each eye was measured with the qCSF method. An ROC analysis (Hou et al., 2016) was conducted to evaluate the accuracy of the methods in detecting changes in visual acuity and area under the log CSF (AULCSF) associated with different foil conditions. The analysis consisted of computing (1) the average acuity from repeated e-ETDRS measures in each eye and foil condition for each subject; (2) posterior distributions of the estimated VA from the new visual acuity and e-ETDRS tests and AULCSF from the qCSF, (3) the accuracy of detecting acuity changes (averaged across all 16 possible combinations of the four repeats in each condition) and AULCSF changes between each pair of foil conditions; (4) the average accuracy in three ranges of mean acuity changes: 0.02-0.05, 0.05-0.10, and 0.10-0.20 logMAR.Results
For detection of visual function change, the qCSF with 50 trials had the highest accuracy (0.996 ± 0.008, 0.996 ± 0.007, and 0.987 ± 0.020 in the three ranges), followed by the new Bayesian visual acuity test with 45 trials or 135 letters (0.874 ± 0.038, 0.910 ± 0.047, and 0.971 ± 0.036), and lastly by the e-ETDRS test with 30.8 ± 5.4 letters (0.826 ± 0.036, 0.808 ± 0.029, and 0.0.905 ± 0.042). Conclusions Bangerter foils produce deficits in visual function beyond visual acuity. The qCSF was the most accurate test for these deficits, and the new Bayesian VA test is more accurate than e-ETDRS in detecting associated visual acuity changes.

digital ACT measures for left and right eye fixing respectively were on average 2.9Δ (95% limit of agreement [LOA]: ±4.6) and 3.0Δ (95% LOA: ±6.1) more eso than the clinical PACT, which may be due to stimuli differences. Measurements were consistent between the two repeats of the digital ACT, with mean differences of -0.4Δ (95% LOA: ± 4.6) and -0.2Δ (95% LOA: ± 5.5) for left and right eye fixing. Conclusions: Low-cost eye trackers and 3D displays can be used to quickly assess ocular deviations at multiple gaze directions. Results strongly correlated with standard clinical PACT. This type of test may be useful in clinical settings, such as for repeated measurements or for children.

Rose, D. & Bex, P.J. (2018) Semantic Scene Statistics Using a Novel Computational Method. Presented at the European Conference on Visual Perception.
Correlations between semantic and image saliency maps, averaged across images in this subset, were modest but highly significant for both semantic saliency map types. The average correlation coefficient for image to object-object saliency maps was 0.35 (one-sample t-test, t=26.5,df =209, p<0.0001); for image to object-scene it was 0.33 (t=25.9, df =209,p<0.0001). ROC analyses of gaze position alignment with salience maps of both types indicate that object-object or object-semantic saliency were significantly better predictors of gaze than image salience across tasks (Tukey HSD post-hoc test, p<0.0001 for both image/object-object and image/object-scene), with equivalent performance between the semantic saliency map types (p=0.68).
Taken together, we believe these results support the use of our method for calculating semantic saliency, alone or in combination with other top-down and bottom up salience models, for predicting gaze. Object-scene semantic saliency in particular represents a novel method for including potentially important information regarding the role of novel or contextually unlikely scene content on gaze guidance.

mouth and forehead, at random across trials) in a 2AFC task. The name or feature of the test face was paired with a name or same feature from a different face. Binocular gaze direction was tracked using a 60Hz eye tracker. Face identification was significantly worse for line drawings than upright faces (p< .0001). Gaze direction varied as a function of face feature (p< 0.001) with more fixations towards the eyes and nose than any other features (all p< 0.05), and more fixations to left than right eye (all p< 0.05). Participants made fewer fixations on the eyes of all non-upright faces or selfies compared to upright faces (all p< 0.05), but fixation patterns were not significantly different for face naming than feature recognition (p<0.87). In agreement with previous research, gaze direction is not uniformly distributed across faces. However, changes in image type can modify the pattern of eye movements at no expense to identification accuracy. Furthermore, changes in task type failed to modify fixation patterns. These findings are not consistent with a single information-driven goal of eye movements

Accurate detection of vision change is important in diagnosing and monitoring visual disease progression and treatment effects. In this study, we evaluated the accuracy of three tests in detecting vision changes: the e-ETDRS (Beck et al., 2003), a new Bayesian visual acuity test (Lesmes, 2017), and qCSF assessment of the contrast sensitivity function (Lesmes, et al, 2010; Hou, et al, 2015).Methods
Monocular visual acuities and contrast sensitivities were measured with the three tests in both eyes of six subjects with normal or corrected-to-normal vision in four simulated vision conditions (no foil and three different levels of Bangerter foil that degraded vision). Each session tested one foil condition. Subjects were tested monocularly with both the new Bayesian visual acuity and e-ETDRS methods 4 times, with random test order of the two methods and two eyes in different blocks. At the end of each session, the contrast sensitivity function of each eye was measured with the qCSF method. An ROC analysis (Hou et al., 2016) was conducted to evaluate the accuracy of the methods in detecting changes in visual acuity and area under the log CSF (AULCSF) associated with different foil conditions. The analysis consisted of computing (1) the average acuity from repeated e-ETDRS measures in each eye and foil condition for each subject; (2) posterior distributions of the estimated VA from the new visual acuity and e-ETDRS tests and AULCSF from the qCSF, (3) the accuracy of detecting acuity changes (averaged across all 16 possible combinations of the four repeats in each condition) and AULCSF changes between each pair of foil conditions; (4) the average accuracy in three ranges of mean acuity changes: 0.02-0.05, 0.05-0.10, and 0.10-0.20 logMAR.Results
For detection of visual function change, the qCSF with 50 trials had the highest accuracy (0.996 ± 0.008, 0.996 ± 0.007, and 0.987 ± 0.020 in the three ranges), followed by the new Bayesian visual acuity test with 45 trials or 135 letters (0.874 ± 0.038, 0.910 ± 0.047, and 0.971 ± 0.036), and lastly by the e-ETDRS test with 30.8 ± 5.4 letters (0.826 ± 0.036, 0.808 ± 0.029, and 0.0.905 ± 0.042). Conclusions Bangerter foils produce deficits in visual function beyond visual acuity. The qCSF was the most accurate test for these deficits, and the new Bayesian VA test is more accurate than e-ETDRS in detecting associated visual acuity changes.

digital ACT measures for left and right eye fixing respectively were on average 2.9Δ (95% limit of agreement [LOA]: ±4.6) and 3.0Δ (95% LOA: ±6.1) more eso than the clinical PACT, which may be due to stimuli differences. Measurements were consistent between the two repeats of the digital ACT, with mean differences of -0.4Δ (95% LOA: ± 4.6) and -0.2Δ (95% LOA: ± 5.5) for left and right eye fixing. Conclusions: Low-cost eye trackers and 3D displays can be used to quickly assess ocular deviations at multiple gaze directions. Results strongly correlated with standard clinical PACT. This type of test may be useful in clinical settings, such as for repeated measurements or for children.

Rose, D. & Bex, P.J. (2018) Semantic Scene Statistics Using a Novel Computational Method. Presented at the European Conference on Visual Perception.
Correlations between semantic and image saliency maps, averaged across images in this subset, were modest but highly significant for both semantic saliency map types. The average correlation coefficient for image to object-object saliency maps was 0.35 (one-sample t-test, t=26.5,df =209, p<0.0001); for image to object-scene it was 0.33 (t=25.9, df =209,p<0.0001). ROC analyses of gaze position alignment with salience maps of both types indicate that object-object or object-semantic saliency were significantly better predictors of gaze than image salience across tasks (Tukey HSD post-hoc test, p<0.0001 for both image/object-object and image/object-scene), with equivalent performance between the semantic saliency map types (p=0.68).
Taken together, we believe these results support the use of our method for calculating semantic saliency, alone or in combination with other top-down and bottom up salience models, for predicting gaze. Object-scene semantic saliency in particular represents a novel method for including potentially important information regarding the role of novel or contextually unlikely scene content on gaze guidance.

mouth and forehead, at random across trials) in a 2AFC task. The name or feature of the test face was paired with a name or same feature from a different face. Binocular gaze direction was tracked using a 60Hz eye tracker. Face identification was significantly worse for line drawings than upright faces (p< .0001). Gaze direction varied as a function of face feature (p< 0.001) with more fixations towards the eyes and nose than any other features (all p< 0.05), and more fixations to left than right eye (all p< 0.05). Participants made fewer fixations on the eyes of all non-upright faces or selfies compared to upright faces (all p< 0.05), but fixation patterns were not significantly different for face naming than feature recognition (p<0.87). In agreement with previous research, gaze direction is not uniformly distributed across faces. However, changes in image type can modify the pattern of eye movements at no expense to identification accuracy. Furthermore, changes in task type failed to modify fixation patterns. These findings are not consistent with a single information-driven goal of eye movements

Accurate detection of vision change is important in diagnosing and monitoring visual disease progression and treatment effects. In this study, we evaluated the accuracy of three tests in detecting vision changes: the e-ETDRS (Beck et al., 2003), a new Bayesian visual acuity test (Lesmes, 2017), and qCSF assessment of the contrast sensitivity function (Lesmes, et al, 2010; Hou, et al, 2015).Methods
Monocular visual acuities and contrast sensitivities were measured with the three tests in both eyes of six subjects with normal or corrected-to-normal vision in four simulated vision conditions (no foil and three different levels of Bangerter foil that degraded vision). Each session tested one foil condition. Subjects were tested monocularly with both the new Bayesian visual acuity and e-ETDRS methods 4 times, with random test order of the two methods and two eyes in different blocks. At the end of each session, the contrast sensitivity function of each eye was measured with the qCSF method. An ROC analysis (Hou et al., 2016) was conducted to evaluate the accuracy of the methods in detecting changes in visual acuity and area under the log CSF (AULCSF) associated with different foil conditions. The analysis consisted of computing (1) the average acuity from repeated e-ETDRS measures in each eye and foil condition for each subject; (2) posterior distributions of the estimated VA from the new visual acuity and e-ETDRS tests and AULCSF from the qCSF, (3) the accuracy of detecting acuity changes (averaged across all 16 possible combinations of the four repeats in each condition) and AULCSF changes between each pair of foil conditions; (4) the average accuracy in three ranges of mean acuity changes: 0.02-0.05, 0.05-0.10, and 0.10-0.20 logMAR.Results
For detection of visual function change, the qCSF with 50 trials had the highest accuracy (0.996 ± 0.008, 0.996 ± 0.007, and 0.987 ± 0.020 in the three ranges), followed by the new Bayesian visual acuity test with 45 trials or 135 letters (0.874 ± 0.038, 0.910 ± 0.047, and 0.971 ± 0.036), and lastly by the e-ETDRS test with 30.8 ± 5.4 letters (0.826 ± 0.036, 0.808 ± 0.029, and 0.0.905 ± 0.042). Conclusions Bangerter foils produce deficits in visual function beyond visual acuity. The qCSF was the most accurate test for these deficits, and the new Bayesian VA test is more accurate than e-ETDRS in detecting associated visual acuity changes.
