Effect of Icon Styles on Cognitive Absorption and Behavioral Intention of Low Literate Users

Information and communication technologies (ICT) are being considered as one of the most potential medium for bringing more efficient and sustainable solution for many problems faced by different communities belong to the middle of economic pyramid of developing countries. Mobile phone based applications can offer many potential solutions for such problems. Existing solutions which are quite successful at the top of the pyramid user population often prove itself ineffective at the middle of the pyramid naïve low-literate users. In this context interface designers also face considerable challenges due to lack of consolidate icon design methodology which can be adapted for the target user sections. Therefore we propose an empirical study to address the requirement of concrete icon design methodology. Grounded in ‘Cognitive Absorption’ and ‘Theory of Metaphor’ we propose a concrete design guidelines specifically for designing icons to ensure instant learning, usage and adaptation of the system for daily usage. A mobile pest management system is developed to bring the real context on which design methodologies and the role of cognitive absorption and metaphor can be examined to identify the most appropriate one. Our preliminary study suggests a comprehensive icon design methodology and its effect on cognitive absorption as well as behavioral intention for low literate novice users

Icon Types, Classical and Expressive Aesthetics, Pleasurable Interaction and Satisfaction with the Process of Semi-literate Users

The hedonic role of icons has been undermined in contemporary human computer interaction research, though users have specifically mentioned the importance of icons while performing aesthetic evaluation of user interfaces. Previous research has also neglected factors like aesthetics and pleasurable interaction while comparing efficiency of same interface elements. In this regard, current study investigates how different types of icons in mobile applications affect the aesthetics and pleasurable interactions of semi-literate users. This study also investigates the extent to which aesthetics and pleasurable interactions affect satisfaction with the process. The study addresses these issues from the theoretical perspectives of metaphor and aesthetics. Significant differences were observed for aesthetics and pleasurable interactions between two different types of icon sets, namely metaphoric and idiomatic. This study suggests that for higher evaluation of aesthetics and pleasurable interaction for semi-literate users, specific icon types are preferred

Acute onset movement disorders in diabetes mellitus: A clinical series of 59 patients

Background and purpose: No previous study has assessed the frequency and clinical– radiological characteristics of patients with diabetes mellitus (DM) and acute onset non-choreic and nonballistic movements. We conducted a prospective study to investigate the spectrum of acute onset movement disorders in DM.Methods: We recruited all the patients with acute onset movement disorders and hyper-glycemia who attended the wards of three hospitals in West Bengal, India from August 2014 to July 2021.Results: Among the 59 patients (mean age = 55.4± 14.3 years, 52.5% men) who were included, 41 (69.5%) had choreic or ballistic movements, and 18 (30.5%) had nonchoreic and nonballistic movements. Ballism was the most common movement disorder (n= 18, 30.5%), followed by pure chorea (n= 15, 25.4%), choreoathetosis (n= 8, 13.6%), tremor (n= 5, 8.5%), hemifacial spasm (n= 3, 5.1%), parkinsonism (n= 3, 5.1%), myoclonus (n= 3, 5.1%), dystonia (n= 2, 3.4%), and restless leg syndrome (n= 2, 3.4%). The mean duration of DM was 9.8 ± 11.4 years (89.8% of the patients had type 2 DM). Nonketotic hypergly-cemia was frequently (76.3%) detected. The majority (55.9%) had no magnetic resonance imaging (MRI) changes; the remaining showed striatal hyperintensity. Eight patients with MRI changes exhibited discordance with sidedness of movements. Most of the patients (76.3%) recovered completely.Conclusions: This is the largest clinical series depicting the clinical–radiological spectrum of acute onset movement disorders in DM. Of note was that almost one third of patients had nonchoreic and nonballistic movements. Our findings highlight the importance of a capillary blood glucose measurement in patients with acute or subacute onset movement disorders, irrespective of their past glycemic status
