Infants double their weight in the first 4 months of life and triple it by the end of the first year. The transition from purely milk intake to solid foods is a key part of a baby's development. Failure to adequately make this transition can severely affect a child's long term development. Virtual reality offers a means of helping instruct parents in appropriate ways of feeding their child, in a safe and controlled manner. This paper is an experimental study, which deals with the evaluation of common input devices in terms of virtual reality application intended for parents of infants with feeding problems. The aim of the application is to give parents an alternative to gain experience with. The task is to measure users' ability to manipulate with 3D object in VR environment and the survey to determine what advantages and disadvantages of each device users can see regarding the important characteristics of device for the task. A gamepad, a space navigator, a keyboard with mouse and a nunchuck with a Wii Remote were used for the purpose of this study. Description of the properties and capabilities of individual devices is provided as well as limitations based on a survey among the participants. This may in turn aid us in understanding how to use virtual applications for new parents who may be concerned about appropriate baby feeding.
[Show abstract][Hide abstract] ABSTRACT: Currently a considerable amount of time and resources are spent helping parents overcome issues related to feeding young infants. Designing interactive virtual feeding scenarios is a preventative means to reduce the adaptation process time for newly made parents, but also help new parents improve their approach to feeding their children. In this paper, we present a case study on using and assessing a virtual reality infant feeding application. Our results show that virtual training can increase the efficiency of feeding depending on the different behaviour of the child.

[Show abstract][Hide abstract] ABSTRACT: In this paper we investigate how different conditions aiding perception in an online Virtual Reality application affect depth perception. The VR was developed for parents experiencing feeding difficulties with their infants. The role of effective use of stereoscopic viewing, head tracking and animation is examined. In a complete block designed experiment subjects were asked to determine the positions of the spoon in the 3D environment. Task was done under different conditions: the animation of the baby model was either on or off and four different viewing modes were used: monoscopic or stereoscopic viewing with or without head tracking. The use of head tracking improved the position perception when monoscopic vision without any animation applied. However, adding head tracking to stereo vision did not improve the position perception. The use of animation positively affected the judgment of depth perception under the monoscopic vision and makes it comparable with the performance under the head tracking mode. The outcome of this study provides insight into how to create more interactive scene and enhance depth-related visual tasks by exploiting dynamic scene changes.
[Show abstract][Hide abstract] ABSTRACT: Parental reports suggest that difficulties related to child-feeding and children's eating behaviour are extremely common. While 'fussy eating' does not pose an immediate threat to health, over the long-term, consumption of a poor diet can contribute to the development of a range of otherwise preventable diseases. In addition, the stress and anxiety that can surround difficult mealtimes can have a detrimental impact upon both child and parental psychological wellbeing. Since parents have a great influence over what, when, and how much food is offered, feeding difficulties may be preventable by better parental awareness. The aim of this review is to describe how parental factors contribute to the development of common feeding problems, and to discuss the merits of existing interventions aimed at parents/primary caregivers to improve child-feeding and children's eating behaviour. The potential for different technologies to be harnessed in order to deliver interventions in new ways will also be discussed.
