A Survey of Addictive Software Design

The average smartphone owner checks their phone more than 150 times per day. As of 2015, 62% of smartphone users had used their phone to look up information about a health condition, while 57% had used their phone to do online banking. Mobile platforms have become the dominant medium of human-computer interaction. So how have these devices established themselves as our go to connection to the Internet? The answer lies in addictive design. Software designers have become well versed in creating software that captivates us at a primal level. In this article, we survey addictive software design strategies, their bases in psychology, and their applications in popular software products. We offer a novel taxonomy to better categorize these addictive design strategies. Additionally, we explore a study conducted at the California Polytechnic State University at San Luis Obispo that illustrates the efficacy of one of the addictive design strategies

Reports of injury risks and reasons for choice of sleep environments for infants and toddlers

OBJECTIVE: Compare mothers\u27 reports of injuries for infants and toddlers sleeping with crib-bumpers/mesh-liners/no-barriers and reasons for these sleep environment choices. METHODS: A cross-sectional survey of mothers subscribing to a parenting magazine and using crib bumpers (n = 224), mesh liners (n = 262), and no barriers (n = 842). Analyses of four possible injuries (face-covered, climb-out/fall, slat-entrapment, hit-head) including multivariate logistic regression adjusted for missing data/demographics and Chi squared analyses of reasons for mothers\u27 choices. RESULTS: Maternal reports of finding infants/toddlers with face covered had 3.5 times higher adjusted odds (aOR) for crib bumper versus mesh liner use. Breathing difficulties and wedgings were reported for infants/toddlers using crib bumpers but not mesh liners. Climb-outs/falls showed no significant difference in aORs for crib bumpers versus no-barriers and mesh liners versus no barriers. Reports of slat-entrapment were less likely for mothers using crib bumpers and mesh liners than using no barrier (aOR = .28 and .32). Reports of hit-heads were less likely for crib bumpers vs no barrier (aOR = .38) with no significant difference between mesh liners versus no barrier use. Mothers using crib bumpers and mesh liners felt their choice prevented slat-entrapment (89%, 91%); 93.5% of crib bumper users felt their choice prevented hit-heads. Significantly more mesh liner than crib bumper users chose them because There is no suffocation risk (64.1% vs. 40.6%), while 83.6% of no-barrier users chose them because I was concerned about suffocation risk. CONCLUSIONS FOR PRACTICE: Mothers appeared to be more concerned about preventing minor risks than suffocation. Understanding reasons for mothers\u27 use of barriers/no-barriers is important in tailoring counseling for mothers with infants/toddlers

Girl I\u27ll Call My Sweetheart Must Look Like You

[Verse 1] Now while oft I’ve been wandering, sad and alone, I’ve just dreamed, dreamed, dreamed Of a pair of blue eyes that delightfully shone, and how grand they seem’d! They would stare at me, glare at me, try to console, and what could I do? When at times they would look into my very soul and say: “I love you.” [Chorus] The girl I’ll call my sweetheart must have eyes of Irish blue, And her cheeks must blush like roses fondly kiss’d by morning dew. She must vow to love me truly, And love old Ireland too; For the girl I’ll call my sweetheart must look like you. [Verse 2] All around me they now cast their sweet magic spell under moon or sun, And I’m longing my story of true love to tell to the only one. Sure, today such a beautiful vision I’ve seen of a sweet colleen; I believe that I soon will be claiming the hand of my Fairy queen. [Chorus

Programmable Immersive Peripheral Environmental System (PIPES): A Prototype Control System for Environmental Feedback Devices

This paper describes an environmental feedback device (EFD) control system aimed at simplifying the VR development cycle. Programmable Immersive Peripheral Environmental System (PIPES) affords VR developers a custom approach to programming and controlling EFD behaviors while relaxing the required knowledge and expertise of electronic systems. PIPES has been implemented for the Unity engine and features EFD control using the Arduino integrated development environment. PIPES was installed and tested on two VR systems, a large format CAVE system and an Oculus Rift HMD system. A photocell based end-to-end latency experiment was conducted to measure latency within the system. This work extends previously unpublished prototypes of a similar design. Development and experiments described in this paper are part of the VR community goal to understand and apply environment effects to VEs that ultimately add to usersâ perceived presence

Highly Loaded Composite Strut Test Development

Highly loaded composite struts, representative of structural elements of a proposed truss-based lunar lander descent stage concept, were selected for design, development, fabrication and testing under NASA s Advanced Composites Technology program. The focus of this paper is the development of a capability for experimental evaluation of the structural performance of these struts. Strut lengths range from 60 to over 120 inches, and compressive launch and ascent loads can exceed -100,000 lbs, or approximately two times the corresponding tensile loads. Allowing all possible compressive structural responses, including elastic buckling, were primary considerations for designing the test hardware
