TL;DR: In this paper, the authors examined 77 ambulant elderly persons meeting NINCDS criteria for Alzheimer's disease their drawings of clock faces and overlapping pentagons and found that the clock drawing test had moderate correlation with their total scores on the CAMCOG and Mini Mental State Exam (MMSE).
Abstract: Clock drawing is described as a novel, easily administered bedside measure of cognitive function. We examined from 77 ambulant elderly persons meeting NINCDS criteria for Alzheimer's disease their drawings of clock faces and overlapping pentagons. Interrater reliability for two previously published scoring scales for clocks and a devised ordinal scale for overlapping pentagons was high. There was moderate correlation with their total scores on the CAMCOG and Mini Mental State Exam (MMSE). However, a considerable number of patients scored within the normal range on all three drawing scales. A third (23/77) on clock drawing demonstrated their only abnormality at setting the time to 10 to 11 instead of the requested 10 past 11. For the clock drawing test to be used as a rapid screening instrument for Alzheimer's disease in the community an accurately drawn clock face must include the correct position of the hands. The pentagon test either alone or in combination did not enhance the accuracy of the clock test.
TL;DR: In this article, a method for resetting a real-time clock of a pen-based computer system characterized by the steps of displaying an image of an analog clock face with an hour hand and a minute hand on the screen of the computer was presented.
Abstract: A method for resetting a real-time clock of a pen-based computer system characterized by the steps of: displaying an image of an analog clock face with an hour hand and a minute hand on the screen of a pen-based computer system; determining whether a clock-setting stroke has been made with a stylus upon the image of the analog clock face; resetting the real-time clock to correspond to the clock-setting stroke; and moving at least one of the hour hand and the minute hand in response to the clock-setting stroke. An apparatus for resetting a real-time clock of a pen-based computer system is characterized by: a digital processor; a real-time clock coupled to the digital processor; a screen assembly coupled to the digital processor; a display mechanism for displaying an image of an analog clock on the screen assembly; a detection mechanism for detecting a clock-resetting stroke on the image of the analog clock by a stylus; and a resetting mechanism for resetting the real-time clock in response to the clock-resetting stroke.
TL;DR: In this paper, a graphical representation of a circular analog clock face is used to select an hour and a minute value in a single point-and-click operation by moving a cursor into the appropriate subsector within the appropriate sector and then performing a cursor select operation.
Abstract: Time values (hour, minute, AM/PM parameter) can be simply and quickly set in a computer system using a graphical representation of a circular analog clock face. Time setting zones (hour-indicative sectors and minute-indicative subsectors) are defined on the displayed clock face. A user selects an hour and a minute value in a single point-and-click operation by moving a cursor into the appropriate subsector within the appropriate sector and then performing a cursor select operation. Two different approaches are described for choosing an AM or a PM parameter to be associated with the selected time value.
TL;DR: It was determined that left visuospatial neglect specific to the upper quadrant was relatively common in 6- and 7-year olds but not evidenced by age 8, and development of clock face drawing most closely paralleled that of frontal lobe maturation.
Abstract: The clock drawing test has been routinely administered by many neuropsychologists as part of their testing battery with the adult population. Our study investigated the development of clock face drawing in normal children ages 6 to 12 years. Conceptualization of time and construction of the clock face were assessed by an adapted scoring system developed as part of the investigation. As a group, the results indicated an upward progression with regard to the concept of time through age 8 and clock construction through age 12. Results further demonstrated that number reversals were more frequent among left-handers but were no longer evident by age 7 regardless of handedness. It also was determined that left visuospatial neglect specific to the upper quadrant was relatively common in 6- and 7-year olds but not evidenced by age 8. Given the pattern of the findings, it is likely that the neglect was secondary to poor planning and not a visuo-spatial deficit. In general, development of clock face drawing most cl...
TL;DR: In this article, a counting device is a clock hand which sweeps across a clock face, and the winner is the first player to make his clock hand reach the predetermined total. But in this case the counting devices of the respective machines are rendered inoperative and the winning player can be ganged so that the players play against each other.
Abstract: A gaming apparatus comprising a plurality of gaming machines is provided. Each machine can be operated individually, the player upon each start of the machine endeavouring to reach a predetermined objective by his skill in propelling a ball into apertures to reach a predetermined total before a counting device in the machine which is started upon starting of the machine, reaches that total. The player thus competes against the machine in individual operation thereof. In the embodiment described the counting device is a clock hand which sweeps across a clock face. The players performance is indicated by a clock hand sweeping across the same clock face. The clock face and both hands are visible to the player to provide excitement. All of the machines can be ganged so that the players play against each other, but in this case the counting devices of the respective machines are rendered inoperative and the winner is the first player to make his clock hand reach the predetermined total.
