Abstract:

There has been a recent increase in debates on the ethics of social media research, passive sensor data collection, and big data analytics. However, little evidence exists to describe how people experience and understand these applications of technology. This study aimed to passively collect data from mobile phone sensors, lapel cameras, and Bluetooth beacons to assess people’s understanding and acceptance of these technologies. Seven households were purposefully sampled and data collected for 10 days. The study generated 48 hr of audio data and 30,000 images. After participant review, the dat

Abstract:

A marker-based optical motion capture system is often used to obtain the kinematics parameters of a running analysis. However, the attached marker could affect the participant's movement, and the system is costly because of the exclusive cameras. Due to its drawbacks, the present research aimed to develop an affordable markerless optical motion capture system for running motion. The proposed system used an action sports camera to acquire the running images of the participant. The images were segmented to get the silhouette of the participant. Then, a human body model was generated to provide a

Conventionally, spectators enjoy films passively. This paper describes an interactive film installation that invites participants to use their entire body as a query to search and explore a large corpus of musical films in a novel way. Using an RGB camera, ML-based skeleton tracking technology and a unique pose and film indexing system, this installation tracks a participant's movements and mirrors them in real-time by finding matching poses among hundreds of thousands from well-known musicals.

Personally curated content in short-form video formats provides added value for participants and spectators but is often disregarded in lower-level events because it is too labor-intensive to create or is not recorded at all.

The relevant parts of the video for each participant are automatically determined by using the timestamps of his/her received sensor data. This is achieved through

Five dyads, who were part of a randomized clinical trial testing an intervention to promote parent-child communication, participated in a structured interview. All parents were mothers. Youth were eighth graders. Three were boys and two were girls. Findings

Abstract:

Design thinking process has two ways of on and off-line. In the online method, it facilitates communication more freely through the setting of anonymity, while the offline method allows participants to understand the comprehensive context of the workshop. This study investigates the creative possibility of a hybrid design thinking process through a workshop using “camera-off ”: anonymous setting, “camera-on”: open setting, and instant visualization to find solutions for children’s safety in the childcare environment. In the methodology, a qualitative method of three-dimensional interviews and

Abstract:

Practical experience has shown that teleoperators have difficulty perceiving aspects of remotely operated robots and their environments (e.g., Casper & Murphy, 2003; Smets, 1995; Tittle, Roesler, & Woods, 2002). Previous research has shown that head motions can provide effective information about depth (Bingham, & Pagano, 1998; Pagano & Bingham, 1998). In three experiments, a method for improving depth perception was investigated, where participants viewed remote targets with a moving camera. The camera was mounted on a teleoperated robotic arm that oscillated toward and away f

Abstract:

In urban environments, humans often encounter other people that may engage one in interaction. How do humans perceive such invitations to interact at a glance? We briefly presented participants with pictures of actors carrying out one of 11 behaviors (e.g., waving or looking at a phone) at four camera-actor distances. Participants were asked to describe what they might do in such a situation, how they decided, and what stood out most in the photograph. In addition, participants rated how likely they deemed interaction to take place. Participants formulated clear responses about how they might

Abstract:

How does volitional photo taking affect unaided memory for visual and auditory aspects of experiences? Across one field and three lab studies, we found that, even without revisiting any photos, participants who could freely take photographs during an experience recognized more of what they saw and less of what they heard, compared with those who could not take any photographs. Further, merely taking mental photos had similar effects on memory. These results provide support for the idea that photo taking induces a shift in attention toward visual aspects and away from auditory aspects of an exp

Abstract Attention monitoring system is important for various tasks such as driving by alarming the person when he or she is not attending to the task at hand. Past research has not explored a usable attention monitoring system. In the current study, we used eye trackers, depth camera, and infrared cameras to assess the attention of the participants as they read texts. We extracted features from eye tracking and camera data, and then used convolutional neural network to predict the attention state of the participants. We found the eye tracker data yielded a 90% accuracy in predicting attention

Abstract:

We introduce Friendscope, an instant, in-the-moment experience sharing system for lightweight commercial camera glasses. Friendscope explores a new concept called a shared camera. This concept allows a wearer to share control of their camera with a remote friend, making it possible for both people to capture photos/videos from the camera in the moment. Through a user study with 48 participants, we found that users felt connected to each other, describing the shared camera as a more intimate form of livestreaming. Moreover, even privacy-sensitive users were able to retain their sense of privacy

Under the pretext of a problem-solving study, pairs of participants (N = 109) and confederates worked on an individual task with a dividing wall obstructing their view of each other. When the mobile phone of the experimenter was missing from an adjacent room at the end of the session, all participants confirmed that the confederate had not left the room.

Air-writing is a modern human–computer interaction technology that allows participants to write words or letters with finger or hand movements in free space in a simple and intuitive manner. Air-writing recognition is a particular case of gesture recognition in which gestures can be matched to write characters and digits in the air. Air-written characters show extensive variations depending on the various writing styles of participants and their speed of articulation, which presents quite a difficult task for effective character recognition. In order to solve these difficulties, this current w

The study tests the efficacy of a new sort of digital picture book. It includes camera movements to guide children’s visual attention through the pictures and the possibility to control page-turning and the pace at which the camera moves through pictures. There were 56 participants (Mage = 60.34 months, SD = 6.24) randomly assigned to three conditions: still images, camera movements (no control over pace), and camera movements (control over pace). For the 50% of children least proficient in language skills, sparingly adding well-chosen camera movements to the illustrations helps children under

A user interface evaluation technique has been developed that: a) accurately documents user inputs and system responses; b) follows the logic behind user actions; c) obtains behavior that is not biased by the evaluation technique; d) does not cause the participants to feel uncomfortable; and, e) easily illustrates user interface problems to others. The basic technique involves participants working in pairs, direct video recording of screen images without a camera, and audio recording on the same videotape of the users' verbal interactions.

Abstract:

Teleoperation services are expected to operate on-road and often in urban areas. In current teleoperation applications, teleoperators gain a higher viewpoint of the environment from a camera on the vehicle’s roof. However, it is unclear how this viewpoint compares to a conventional viewpoint in terms of safety, efficiency, and mental workload. In the current study, teleoperators (n = 148) performed driving tasks in a simulated urban environment with a conventional viewpoint (i.e., the simulated camera was positioned inside the vehicle at the height of a driver’s eyes) and a higher viewpoint (t
