The polytene chromosomes of Drosophila melanogaster consist of condensed heterochromatin regions most of which are in the chromocenter, telomeres, and the fourth chromosome. Whereas suppressor of variegation 3-9 [SU(VAR)3-9], a histone methyltransferase, is mainly responsible for lysine 9 of histone H3 (H3K9) methylation of the chromocenter and consequent(More)
In this paper, we explore the challenges in applying and investigate methodologies to improve direct-touch interaction on intangible displays. Direct-touch interaction simplifies object manipulation, because it combines the input and display into a single integrated interface. While traditional tangible display-based direct-touch technology is commonplace,(More)
We present <i>TUIC</i>, a technology that enables tangible interaction on capacitive multi-touch devices, such as iPad, iPhone, and 3M's multi-touch displays, without requiring any hardware modifications. TUIC simulates finger touches on capacitive displays using passive materials and active modulation circuits embedded inside tangible objects, and can be(More)
Location-aware services can benefit from accurate and reliable indoor location tracking. The widespread adoption of 802.11x wireless LAN as the network infrastructure creates the opportunity to deploy WiFi-based location services with few additional hardware costs. While recent research has demonstrated adequate performance, localization error increases(More)
This paper presents CyclopsRing, a ring-style fisheye imaging wearable device that can be worn on hand webbings to en- able whole-hand and context-aware interactions. Observing from a central position of the hand through a fisheye perspective, CyclopsRing sees not only the operating hand, but also the environmental contexts that involve with the hand-based(More)
We present FingerPad, a nail-mounted device that turns the tip of the index finger into a touchpad, allowing private and subtle interaction while on the move. FingerPad enables touch input using magnetic tracking, by adding a Hall sensor grid on the index fingernail, and a magnet on the thumbnail. Since it permits input through the pinch gesture, FingerPad(More)
Thumb-to-fingers interfaces augment touch widgets on fingers, which are manipulated by the thumb. Such interfaces are ideal for one-handed eyes-free input since touch widgets on the fingers enable easy access by the stylus thumb. This study presents DigitSpace, a thumb-to-fingers interface that addresses two ergonomic factors: hand anatomy and touch(More)
Many map systems are created to help the user finding a place or define a route to follow. Google Map extends the concept of "surfing the map" by adding a street view that allows the user to explore a place from real pictures, creating the same feeling of walking through the streets. The horizontal 2D map and vertical panoramic street view, however, cause(More)
In this paper, we explored eyes-free gesture interactions on palms, which enables users to interact with devices by drawing stroke gestures on palms without looking at palms. We conducted a 24-person user study to understand how users draw gestures on the palm with varying characteristics including regions, orientation and starting points. Based on the(More)
This work presents a novel and always-available nail mounted display known as <i>NailDisplay</i>. The proposed display augments the use of a finger by allowing for always-available visual feedback owing to its fast accessibility and binding user controls with the display, <i>i.e.</i> what you control is what you see (through the display). Potential benefits(More)
