Block diagram showing the functioning of the glove based typing device. Participants wore gloves (showed with dotted lines) such that the tactile switches on the glove faced towards the participants. The hand is represented with bold lines. Key patches (showed as square around the alphabets) were sewed on the dorsal side of each finger segment on the gloves. Conductive threads, sewed on the glove were used to connect the key patches to a button connector, which was used to interface with the microcontroller. When an symbol patch was touched with thumb, a custom-written code in the microcontroller converted the touch into text. This was shown on the computer monitor.

... dataset presented in the article was collected using a glove based typing device as shown in Fig. 1. The right handed participants were recruited to use the glove based typing device to type the words shown in a game like interface as seen in Fig. 2. The words shown to the participants are tabulated in Table 2. The data collected is organized into folders and subfolders for easy accessibility and reusability by fellow researchers in ...

... * 4 fingers ¼ 12 keys) and one at the distal thumb (tip). Among these 13 keys, the one on the thumb was used as a switch, while the 12 on the other fingers were assigned with nine specific symbols, space, backspace, and caps lock. These keys were connected to a microcontroller (Teensy 2.0þþ) using conductive thread, metallic buttons, and cables. Fig. 1 illustrates the experimental setup and the keymap used. In order to type a particular letter, participants had to touch the corresponding key patch on a finger with the thumb, which then closed a specific electrical circuit. A customized program in the microcontroller detected this event, and the program then sent the ASCII Table 1 ...

The third column indicates key press and release activities in terms of seconds. code of that specific key to the computer through a USB port. For example, when the participant touched middle phalanx of the index finger, symbol 'S' was typed on the computer screen as shown in Fig. 1. These gloves were custom-made to suit the hand dimensions for each participant. The text from the glove was processed by a customized LabVIEW based program at 1000 ...

... wore the glove and were instructed to make opposition movement with the thumb as seen in Fig. 1, to the finger phalanx to type-specific symbols. For example, when the participant touched middle phalanx of the index finger, symbol 'S' was typed on the computer screen as shown in Fig. 1. Hence, the task involved learning of set of training sequences by typing them using their finger thumb opposition movements. This task is known as ...

... used in the experiment were 5-letter words picked from a custom dictionary (Please see Table 2 for sequences used in the experiment). This dictionary comprised 281 sequences, each made using five of the nine most frequently used symbols (e, s, o, n, i, t, a, r, h). These symbols were mapped to keys on the glove to form a keymap, as shown in Fig. 1 (placed on the gloves). For all participants, the same keymap was used on all days and blocks. First eleven blocks comprised of 23 sequences, while the twelfth block had five more sequences than other blocks of the practice session. Hence, the total number of sequences were 23 Â 11 ¼ 253 þ 28 (12th block) ¼ 281 sequences. These 281 words ("sequences") were ...
