Abstract: The potential of mucoadhesive delivery system for sustained delivery of drug has been established few decades back.Different polymeric systems such as single or combined, substituted, conjugated, pre-activated polymer (s) etc. are used to develop such delivery platform.To explain the mucoadhesion mechanism, several possible theories namely electronic theory, adsorption theory, wetting theory, diffusion theory, fraction theory and mechanical theory have been proposed.But none of these theories alone can explain the mechanism of mucoadhesion.Various mechanisms of mucoadhesion or bioadhesion between polymer and mucin such as H bonding, electrostatic interactions, di-sulfide linkage, van Der Waals attraction etc have been evidenced.Researches are focused to enrich such interaction between the mucous layer and the delivery platform by modifying the system.Wide varieties of polymers such as cationic, anionic, non-ionic, thiolated polymers etc have been used to design and develop mucoadhesive drug delivery system.Therefore reviewing and analyzing the mucoadhesive polymeric system and their mechanism of action is still relevant and necessary.The aim of this current review is to highlight the polymers which are being used under recent scientific researches with emphasis on their mechanism of mucoadhesion.The result of this critique will assist researchers to screen the mucoadhesive polymers for their designated purpose.

Abstract: We designed, implemented, and evaluated a small physical keyboard, composed of four to five keys with a variety of mappings for the letters, along with one or two navigational function keys operated by the thumb. The small size allows it to be used for smartwatch text entry, and can be mounted on various body parts as a wearable keyboard. It is primarily used as an ambiguous keyboard, akin to T9, although a multi-tap mode is also present. Our keyboard layouts include Alphabetic, Collapsed QWERTY, Mnemonic (where letters are grouped based on their shapes), and Optimized (which minimizes the number of conflicts). In a between-users study, participants achieved an average of 15.4 words per minute (WPM) across all layouts, with one user with the Collapsed QWERTY layout reaching a top speed of 30.6 WPM after 4 hours of practice. User feedback was generally favorable.

Abstract: We present MarkPad, a novel interaction technique taking advantage of the touchpad. MarkPad allows creating a large number of size-dependent gestural shortcuts that can be spatially organized as desired by the user. It relies on the idea of using visual or tactile marks on the touchpad or a combination of them. Gestures start from a mark on the border and end on another mark anywhere. MarkPad does not conflict with standard interactions and provides a novice mode that acts as a rehearsal of the expert mode. A first study showed that an accuracy of 95% could be achieved for a dense configuration of tactile and/or visual marks allowing many gestures. Performance was 5% lower in a second study where the marks were only on the borders. A last study showed that borders are rarely used, even when the users are unaware of the technique. Finally, we present a working prototype and briefly report on how it was used by two users for a few months.
