There are different wired data transfer technologies such as universal serial bus (USB) and High-Definition Multimedia Interface (HDMI) used to transfer data, video, and audio to and from a mobile device. Thunderbolt is a new technology introduced by Intel to transfer any kind of data at around 10 Gb/s data transfer speeds.
Augmenting television narratives using interactive home appliances
Published in Digital Creativity, 2022
The participants also considered the environmental changes of narratives as interaction cues for inducing sensory effects in living room appliances. Changes in narrative environments are usually accompanied by changes in the brightness, hue, and saturation in the scene, such as changes between day and night, the movement from indoor to outdoor environments, and natural disasters. Therefore, it turned out that lighting was the most typical aspect that can show environmental changes by adjusting overall brightness, hue, and saturation throughout the physical space. For instance, P2 created interactive lighting that changes colour following the sunset in the video (P2-AF4), and P5 described the synchronous blinking of lighting as per the thunderbolt in the video (P5-AF13). Apart from lighting, other ideas employed interactions with the air conditioner (P8-AF5), air purifier (P7-AF1), and humidifier (P6-AF14) according to the temperature, air quality, and humidity changes in the narrative environment.

To demonstrate the developed polishing device, a discarded car shell, which has the features of large size, no concave, and no burr, is used as the polished workspiece to carry out experiment test. We choose a Thunderbolt Leopard A2150 pneumatic angle grinder with large polished diameter as the polishing tool in this experiment. This pneumatic grinder has the advantages of small pallet size, high no-load speed, light weight and low energy consumption. The parameters of this device are set as follows: the radius of polishing tool is r = 54mm, the output speed of angle grinder is v = 300r/min, the distance between the rotation platform and local surface is t = 65mm, the constant of the spring legs and the spring-loaded prismatic joint are k1 = k2 = k3 = k = 6468N/m, the radius of the two platform a = b = 45mm, the height of the telescopic leg p = 48mm. A HP20D industrial robot by YASKAWA company is used as a manipulator arm in this experiment. The arm length of the manipulator is only to control the range that the grinder can reach. The spring stiffness reflects the stiffness of tensegrity-based parallel mechanism, so there is no relationship between grinder type with arm length, spring stiffness. The test site is shown as Figure 7.
Modeling and Predicting Mobile Phone Touchscreen Transcription Typing Using an Integrated Cognitive Architecture

The human data used in Experiment 1 were from a previous study (He et al., 2014). We added new analysis of interkey time (i.e., interkey interval), providing a more detailed account of typing performance. The task was a number typing (digit entry) task. In each trial, a random 10-digit telephone number (grouped into three, three, and four digits, for example, “520–025-1314”) was shown, and the participants were instructed to repeat the same number using the virtual keyboard and then tap the send button. Similar tasks have been used in other studies (Horrey & Wickens, 2004; Reed & Green, 1999). A 4.3-inch HTC ThunderBolt touchscreen smartphone running the Android 2.3.4 operating system was used. The keys on the virtual keyboard were arranged in a QWERTY layout. Each number key has a height of about 7.4 mm and a width of about 4.5 mm. Figure 1 shows the interface.
