On new phenomena of photon from modified double slit experiment

A modified double slit experiment of light was implemented. In the experiment, a spatial shape filter is used to manipulate the shape of cross section of laser beam. When this modified laser beam was shined on the double slit, the intensity distribution of laser beam on double slit is asymmetrical. In this way, the laser light was directed to pass through only one or two slits of double slit in different sections. So the which-way information is predetermined before the photons pass through the slits. At the same time, the visible interference pattern can be observed on a monitor screen after the double slit. A couple of new phenomena had been observed from this experiment. The results of this experiment raise questions about Wave-Particle Duality model of quantum theory, which is the foundation for the Copenhagen explanation that is generally regarded as the principal interpretation of quantum theory. As the observed properties from this experiment cannot be fully explained using the quantum theory, especially the Copenhagen explanation, a new model of photon is proposed. The new model for photon should be also applicable to all other micro entity like electron, atoms, molecules etc., according to L. de Broglie assumption

X ray sensitive area detection device

A radiation sensitive area detection device is disclosed which comprises a phosphor-containing film capable of receiving and storing an image formed by a pattern of incoming x rays, UV, or other radiation falling on the film. The device is capable of fluorescing in response to stimulation by a light source in a manner directly proportional to the stored radiation pattern. The device includes: (1) a light source capable of projecting light or other appropriate electromagnetic wave on the film so as to cause it to fluoresce; (2) a means to focus the fluoresced light coming from the phosphor-containing film after light stimulation; and (3) at least one charged coupled detector or other detecting element capable of receiving and digitizing the pattern of fluoresced light coming from the phosphor-containing film. The device will be able to generate superior x ray images of high resolution from a crystal or other sample and will be particularly advantageous in that instantaneous near-real-time images of rapidly deteriorating samples can be obtained. Furthermore, the device can be made compact and sturdy, thus capable of carrying out x ray or other radiation imaging under a variety of conditions, including those experienced in space

Using Sound to Enhance Users’ Experiences of Mobile Applications

The latest smartphones with GPS, electronic compass, directional audio, touch screens etc. hold potentials for location based services that are easier to use compared to traditional tools. Rather than interpreting maps, users may focus on their activities and the environment around them. Interfaces may be designed that let users search for information by simply pointing in a direction. Database queries can be created from GPS location and compass direction data. Users can get guidance to locations through pointing gestures, spatial sound and simple graphics. This article describes two studies testing prototypic applications with multimodal user interfaces built on spatial audio, graphics and text. Tests show that users appreciated the applications for their ease of use, for being fun and effective to use and for allowing users to interact directly with the environment rather than with abstractions of the same. The multimodal user interfaces contributed significantly to the overall user experience

Ola de la Vida:a social play game

Ola de la Vida (ODLV) is a three-player cooperative game which was produced over the course of 48 hours within Global Game Jam in January 2017, at the Abertay University Jam Site.The Game is a playful intervention (an objects or events which seek to bring people together through play) that aims to invite players to form temporary relationships with their co-players through physical contact, collaboration and coaching during play in a co-located context (i.e. where all players are present in the same play space). The game also seeks to expand the play experience beyond the three players to the wider audience by inviting spectatorship through play as performance.The game was designed by Mona Bozdog, Lynn Parker, Danny Parker, and Alex Pass. Since its inception, it has undergone significant development to enhance its usability (through tutorials) and its features to enhance the development of a community of play, including the introduction of clear player scores and high scores for the game. Lynn Parker contributed to the design of physical interactions within the game, the enhancement of usability through tutorials and scores and the creation of digital art for the game in partnership with Alex Pass.Ola De La Vida as a practice as research work offers design insight into use of spectatorship to create a temporary community around a game and to enhance the facilitation of discussion between active players, previous players, spectators, and semi-spectators. The work builds on the varying levels of participation in play, proposing semi-spectatorship: where players are active in a game but have a critical distance afforded to them by the design of the game which offers them and their co-players (where appropriate) potential benefits in play

Cue usage in volleyball : a time course comparison of elite, intermediate and novice female players

This study compared visual search strategies in adult female volleyball players of three levels. Video clips of the attack of the opponent team were presented on a large screen and participants reacted to the final pass before the spike. Reaction time, response accuracy and eye movement patterns were measured. Elite players had the highest response accuracy (97.50 ± 3.5%) compared to the intermediate (91.50 ± 4.7%) and novice players (83.50 ± 17.6%; p<0.05). Novices had a remarkably high range of reaction time but no significant differences were found in comparison to the reaction time of elite and intermediate players. In general, the three groups showed similar gaze behaviour with the apparent use of visual pivots at moments of reception and final pass. This confirms the holistic model of image perception for volleyball and suggests that expert players extract more information from parafoveal regions

Mirror, Mirror, On The Wall: Collaborative Screen-Mirroring for Small Groups

Screen mirroring has been available to consumers for some time, however if every mobile device in the room supports screen mirroring to the main display (e.g. a shared TV), this necessitates a mechanism for managing its use. As such, this paper investigates allowing users in small intimacy groups (friends, family etc.) to self-manage mirrored use of the display, through passing/taking/requesting the display from whomever is currently mirroring to it. We examine the collaborative benefits this scheme could provide for the home, compared to existing multi-device use and existing screen mirroring implementations. Results indicate shared screen mirroring improves perceived collaboration, decreases dominance, preserves independence and has a positive effect on a group's activity awareness

GazeTouchPass: Multimodal Authentication Using Gaze and Touch on Mobile Devices

We propose a multimodal scheme, GazeTouchPass, that combines gaze and touch for shoulder-surfing resistant user authentication on mobile devices. GazeTouchPass allows passwords with multiple switches between input modalities during authentication. This requires attackers to simultaneously observe the device screen and the user's eyes to find the password. We evaluate the security and usability of GazeTouchPass in two user studies. Our findings show that GazeTouchPass is usable and significantly more secure than single-modal authentication against basic and even advanced shoulder-surfing attacks
