User interface guidelines for the control of interactive television systems via smart phone applications

International audienceThere are a growing number of smart phone applications allowing the user to control their television, set-top box or other entertainment devices. The success of these applications is limited. Based on findings from media studies in Austria and France focusing on how people currently use their TV and iTV systems and associated devices, this article describes recommendations for the design of a smart phone application enabling users to control Internet Protocol Television (IPTV) systems including all connected entertainment devices. Recommendations include the need to allow users to control devices that are related to the IPTV experience (not only the set-top box or television set) and the focus on scenarios of usage like supporting listening to music, enjoying a movie or controlling the connected home. Based on similarities and differences found in the two samples, future smart phone applications for controlling TV will only succeed if they provide meaningful functionalities that satisfy the (varying) user needs, support personalisation and personal usage and respect the limitations of mobile phones with respect to possible parallel activities performed

The bubble user interface: a tangible representation of information to enhance the user experience in IPTV systems

International audienceMedia consumption in the IPTV sector has changed over the past years and decades. It evolved from a linear viewing behavior on just one device, the TV with a few channels, to a connected home entertainment environment with multiple screens. Also user interfaces need to adapt to these new requirements and ensure a good user experience and meet the consumers' needs for natural, straightforward and pleasant method of interacting with their IPTV systems. We have developed a new kind of user interface as a tailor-made alternative to current list or grid menus in order to not only address current limitations of list and grid menus, but to offer a novel and unique way to interact with TV content that makes using an interactive system an event again

Engineering for User Experience: An Interactive TV Case Study

This paper provides an experience report and position paper describing some subjective and personal insights we gained during the design and development of an interactive television application that had the enhancement of the overall user experience as the main target. Goal of this position paper is to point out practical experience that as simple lessons learned can help avoid that a project fails due to simple communication errors or role-specific different expectations

Background

Abstract User-centered Design (UCD) and User Experience (UX) have become important keywords when developing and designing products and services that aim to be successful and competitive on the market. In the area of entertainment oriented services, like interactive TV, new challenges arise, shifting the focus from taskbased usability to highly personal, context-dependent use experiences. In order to improve UX design and assist designers by providing valuable feedback in various development stages, we propose the usage of a set of UX evaluation methods dedicated to the evaluation of entertainment oriented services

Wiener klinische Wochenschrift / Gait disorders in adults and the elderly : A clinical guide

Human gait depends on a complex interplay of major parts of the nervous, musculoskeletal and cardiorespiratory systems. The individual gait pattern is influenced by age, personality, mood and sociocultural factors. The preferred walking speed in older adults is a sensitive marker of general health and survival. Safe walking requires intact cognition and executive control. Gait disorders lead to a loss of personal freedom, falls and injuries and result in a marked reduction in the quality of life. Acute onset of a gait disorder may indicate a cerebrovascular or other acute lesion in the nervous system but also systemic diseases or adverse effects of medication, in particular polypharmacy including sedatives. The prevalence of gait disorders increases from 10% in people aged 6069 years to more than 60% in community dwelling subjects aged over 80 years. Sensory ataxia due to polyneuropathy, parkinsonism and frontal gait disorders due to subcortical vascular encephalopathy or disorders associated with dementia are among the most common neurological causes. Hip and knee osteoarthritis are common non-neurological causes of gait disorders. With advancing age the proportion of patients with multiple causes or combinations of neurological and non-neurological gait disorders increases. Thorough clinical observation of gait, taking a focused patient history and physical, neurological and orthopedic examinations are basic steps in the categorization of gait disorders and serve as a guide for ancillary investigations and therapeutic interventions. This clinically oriented review provides an overview on the phenotypic spectrum, work-up and treatment of gait disorders.(VLID)352324

User Experience Centered Engineering: A Process Model Inspired by Games Development

International audienceFollowing a brief review of standard software engineering processes and examples of software developments in the games industry, a user experience (UX) centered process model is proposed highlighting a set of methods to be performed for the various phases (UX Concept, UX Design, Prototype, System Production, Post Production) and the iterative (and repetitive) stages (Analysis, Design, Implementation, Evaluation)

User Experience as a Parameter to Enhance Automation Acceptance: Lessons from Automating Articulatory Tasks

International audienceIf automation in a system is accepted by users is depending on the perceived usefulness and ease of use of the system. How and if user experience has an effect on acceptance is less explored. Goal of this research was to investigate how user experience is changing when a system is automating articulatory tasks. To investigate this relationship we used a case study from the field of interactive television (TV), automating the task of transferring a movie from the TV to the tablet or providing automatically information on the tablet for the movie running on the TV. The automation was indicated for all the tasks by simply bringing a remote control close to the device. Results show that automation in articulatory tasks has a direct positive influence on the overall user experience (UX) and thus is a candidate to further enhance automation acceptance models

Bringing back the analogue feeling to TV user interfaces - the continuous interaction principle

TV and interactive TV are offering more and more functionality and content. Using the TV has become a complicated task, especially when looking at the selection of content using the remote control. To overcome this problem we have started to develop a new way to enhance remote control interaction with a TV that enables the user to have a special type of haptic feedback when interacting with a TV system called Continuous Interaction Principle. This concept brings a kind of analogue feeling back to the user and aims to enhance the interaction with large numbers of content elements. We present design and development of the continuous interaction principle and discuss current open research question as well as future work
